Reference for writing expressions for attribute mappings in Microsoft Entra ID
Article
In this article
When you configure provisioning to a SaaS application, one of the types of attribute mappings that you can specify is an expression mapping. For these mappings, you must write a script-like expression that allows you to transform your users' data into formats that are more acceptable for the SaaS application.
Syntax overview
The syntax for Expressions for Attribute Mappings is reminiscent of Visual Basic for Applications (VBA) functions.
The entire expression must be defined in terms of functions, which consist of a name followed by arguments in parentheses:
FunctionName(
<<argument 1>>
,
<<argument N>>
)
You can nest functions within each other. For example:
FunctionOne(FunctionTwo(
<<argument1>>
))
You can pass three different types of arguments into functions:
Attributes, which must be enclosed in square brackets. For example: [attributeName]
String constants, which must be enclosed in double quotes. For example: "United States"
Other Functions. For example: FunctionOne(
<<argument1>>
, FunctionTwo(
<<argument2>>
))
For string constants, if you need a backslash ( \ ) or quotation mark ( " ) in the string, it must be escaped with the backslash ( \ ) symbol. For example: "Company name: \"Contoso\""
The syntax is case-sensitive, which must be considered while typing them as strings in a function vs copy pasting them directly from here.
Description:
This function converts both parameters to the binary representation and sets a bit to:
0 - if one or both of the corresponding bits in value1 and value2 are 0
1 - if both of the corresponding bits are 1.
In other words, it returns 0 in all cases except when the corresponding bits of both parameters are 1.
Parameters:
Required/ Repeating
Notes
Example:
BitAnd(&HF, &HF7)
11110111 AND 00000111 = 00000111 so
BitAnd
returns 7, the binary value of 00000111.
CBool
Function:
CBool(Expression)
Description:
CBool
returns a boolean based on the evaluated expression. If the expression evaluates to a non-zero value, then
CBool
returns
True
, else it returns
False
.
Parameters:
Required/ Repeating
Notes
Example:
CBool([attribute1] = [attribute2])
Returns True if both attributes have the same value.
CDate
Function:
CDate(expression)
Description:
The CDate function returns a UTC DateTime from a string. DateTime isn't a native attribute type but it can be used within date functions such as
FormatDateTime
and
DateAdd
.
Parameters:
Required/ Repeating
Notes
Remarks:
The returned string is always in UTC and follows the format
M/d/yyyy h:mm:ss tt
.
Example 1:
CDate([StatusHireDate])
Sample input/output:
INPUT
(StatusHireDate): "2020-03-16-07:00"
OUTPUT
: "3/16/2020 7:00:00 AM" <--
Note the UTC equivalent of the above DateTime is returned
Example 2:
CDate("2021-06-30+08:00")
Sample input/output:
INPUT
: "2021-06-30+08:00"
OUTPUT
: "6/29/2021 4:00:00 PM" <--
Note the UTC equivalent of the above DateTime is returned
Example 3:
CDate("2009-06-15T01:45:30-07:00")
Sample input/output:
INPUT
: "2009-06-15T01:45:30-07:00"
OUTPUT
: "6/15/2009 8:45:30 AM" <--
Note the UTC equivalent of the above DateTime is returned
Description:
Returns the first source value that isn't NULL. If all arguments are NULL and defaultValue is present, the defaultValue is returned. If all arguments are NULL and defaultValue isn't present, Coalesce returns NULL.
Parameters:
Required/ Repeating
Notes
Required
String
Required, variable-number of times. Usually name of the attribute from the source object.
defaultValue
Optional
String
Default value to be used when all source values are NULL. Can be empty string ("").
Flow mail value if not NULL, otherwise flow userPrincipalName
Example: You wish to flow the mail attribute if it's present. If it isn't, you wish to flow the value of userPrincipalName instead.
Expression:
Coalesce([mail],[userPrincipalName])
Sample input/output:
INPUT
(mail): NULL
INPUT
(userPrincipalName): "John.Doe@contoso.com"
OUTPUT
: "John.Doe@contoso.com"
ConvertToBase64
Function:
ConvertToBase64(source)
Description:
The ConvertToBase64 function converts a string to a Unicode base64 string.
Description:
Returns a date/time string representing a date to which a specified time interval is added. The returned date is in the format:
M/d/yyyy h:mm:ss tt
.
Parameters:
Required/ Repeating
Notes
Required
Number
The number of units you want to add. It can be positive (to get dates in the future) or negative (to get dates in the past).
dateTime
Required
DateTime
DateTime representing date to which the interval is added.
When passing a date string as input, use
CDate
function to wrap the datetime string. To get system time in UTC, use the
Now
function.
The
interval
string must have one of the following values:
yyyy Year
m Month
d Day
ww Week
h Hour
n Minute
s Second
Example 1: Generate a date value based on incoming StatusHireDate from Workday
DateAdd("d", 7, CDate([StatusHireDate]))
Example
interval
value
dateTime (value of variable StatusHireDate)
output
DateDiff(interval, date1, date2)
Description:
This function uses the
interval
parameter to return a number that indicates the difference between the two input dates. It returns
a positive number if date2 > date1,
a negative number if date2 < date1,
0 if date2 == date1
Parameters:
Required/Optional
Notes
When passing a date string as input, use
CDate
function to wrap the datetime string. To get system time in UTC, use the
Now
function.
The
interval
string must have one of the following values:
yyyy Year
m Month
d Day
ww Week
h Hour
n Minute
s Second
Example 1: Compare current date with hire date from Workday with different intervals
DateDiff("d", Now(), CDate([StatusHireDate]))
Example
interval
date1
date2
output
Example 2: Combine DateDiff with IIF function to set attribute value
If an account is Active in Workday, set the
accountEnabled
attribute of the user to True only if hire date is within the next five days.
Description:
Takes a date string from one format and converts it into a different format.
Parameters:
Required/ Repeating
Notes
Optional
String
Use this parameter to specify the formatting options that customize string parsing for some date and time parsing methods. For supported values, see DateTimeStyles doc. If left empty, the default value used is DateTimeStyles.RoundtripKind, DateTimeStyles.AllowLeadingWhite, DateTimeStyles.AllowTrailingWhite
inputFormat
Required
String
Expected format of the source value. For supported formats, see .NET custom date and time format strings.
outputFormat
Required
String
Format of the output date.
Output date as a string in a certain format
Example: You want to send dates to a SaaS application like ServiceNow in a certain format. You can consider using the following expression.
Description:
The IgnoreFlowIfNullOrEmpty function instructs the provisioning service to ignore the attribute and drop it from the flow if the enclosed function or attribute is NULL or empty.
Parameters:
Required/ Repeating
Notes
Example 1: Don't flow an attribute if it's null IgnoreFlowIfNullOrEmpty([department])
The above expression drops the department attribute from the provisioning flow if it's null or empty.
Example 2: Don't flow an attribute if the expression mapping evaluates to empty string or null
Let's say the SuccessFactors attribute prefix is mapped to the on-premises Active Directory attribute personalTitle using the following expression mapping: IgnoreFlowIfNullOrEmpty(Switch([prefix], "", "3443", "Dr.", "3444", "Prof.", "3445", "Prof. Dr."))
The above expression first evaluates the Switch function. If the prefix attribute doesn't have any of the values listed within the Switch function, then Switch returns an empty string and the attribute personalTitle is not included in the provisioning flow to on-premises Active Directory.
Function:
IIF(condition,valueIfTrue,valueIfFalse)
Description:
The IIF function returns one of a set of possible values based on a specified condition.
Parameters:
Required/ Repeating
Notes
Required
Variable or Expression
Any value or expression that can be evaluated to true or false.
valueIfTrue
Required
Variable or String
If the condition evaluates to true, the returned value.
valueIfFalse
Required
Variable or String
If the condition evaluates to false, the returned value.
The following comparison operators can be used in the condition:
Equal to (=) and not equal to (<>)
Greater than (>) and greater than equal to (>=)
Less than (<) and less than equal to (<=)
Example: Set the target attribute value to source country attribute if country="USA", else set target attribute value to source department attribute.
IIF([country]="USA",[country],[department])
Known limitations
This section includes limitations and workarounds for the IIF function. For information about troubleshooting user creation issues, see Creation fails due to null / empty values.
The IIF function currently doesn't support AND and OR logical operators.
To implement AND logic, use nested IIF statement chained along the trueValue path.
Example: If country="USA" and state="CA", return value "True", else return "False".
IIF([country]="USA",IIF([state]="CA","True","False"),"False")
To implement OR logic, use nested IIF statement chained along the falseValue path.
Example: If country="USA" or state="CA", return value "True", else return "False".
IIF([country]="USA","True",IIF([state]="CA","True","False"))
If the source attribute used within the IIF function is empty or null, the condition check fails.
Unsupported IIF expression examples:
IIF([country]="","Other",[country])
IIF(IsNullOrEmpty([country]),"Other",[country])
IIF(IsPresent([country]),[country],"Other")
Recommended workaround: Use the Switch function to check for empty/null values. Example: If country attribute is empty, set value "Other". If it's present, pass the country attribute value to target attribute.
Description:
The InStr function finds the first occurrence of a substring in a string.
Parameters:
Required/ Repeating
Notes
InStr("The quick brown fox","quick")
Evaluates to 5
InStr("repEated","e",3,vbBinaryCompare)
Evaluates to 7
IsNull
Function:
IsNull(Expression)
Description:
If the expression evaluates to Null, then the IsNull function returns true. For an attribute, a Null is expressed by the absence of the attribute.
Description:
If the expression is null or an empty string, then the IsNullOrEmpty function returns true. This evaluates to True if the attribute is absent or is present but is an empty string.
The inverse of this function is named IsPresent.
Parameters:
Required/ Repeating
Notes
Example:IsNullOrEmpty([displayName])
Returns True if the attribute isn't present or is an empty string.
IsPresent
Function:
IsPresent(Expression)
Description:
If the expression evaluates to a string that isn't Null and isn't empty, then the IsPresent function returns true. The inverse of this function is named IsNullOrEmpty.
Description:
If the expression can be evaluated to a string type, then the IsString function evaluates to True.
Parameters:
Required/ Repeating
Notes
Item(attribute, index)
Description:
The Item function returns one item from a multi-valued string/attribute.
Parameters:
Required/ Repeating
Notes
Example:Item([proxyAddresses], 1) returns the first item in the multi-valued attribute. Index 0 shouldn't be used.
Function:
Join(separator, source1, source2, …)
Description:
Join() is similar to Append(), except that it can combine multiple source string values into a single string, and each value is separated by a separator string.
If one of the source values is a multi-value attribute, then every value in that attribute is joined together, separated by the separator value.
Parameters:
Required/ Repeating
Notes
Required
String
String used to separate source values when they're concatenated into one string. Can be "" if no separator is required.
source1 … sourceN
Required, variable-number of times
String
String values to be joined together.
Left(String, NumChars)
Description:
The Left function returns a specified number of characters from the left of a string.
If numChars = 0, return empty string.
If numChars < 0, return input string.
If string is null, return empty string.
If string contains fewer characters than the number specified in numChars, a string identical to string (that is, containing all characters in parameter 1) is returned.
Description:
Returns a substring of the source value. A substring is a string that contains only some of the characters from the source string.
Parameters:
Required/ Repeating
Notes
Required
Integer
Index in the source string where substring should start. First character in the string has an index of 1, second character has an index 2, and so on.
length
Required
Integer
Length of the substring. If length ends outside the source string, function returns substring from start index until end of source string.
NormalizeDiacritics(source)
Description:
Requires one string argument. Returns the string, but with any diacritical characters replaced with equivalent nondiacritical characters. Typically used to convert first names and last names containing diacritical characters (accent marks) into legal values that can be used in various user identifiers such as user principal names, SAM account names, and email addresses.
Example: Replace characters containing accent marks with equivalent characters that don't contain accent marks.
Expression:
NormalizeDiacritics([givenName])
Sample input/output:
INPUT (givenName): "Zoë"
OUTPUT: "Zoe"
Function:
Not(source)
Description:
Flips the boolean value of the source. If source value is True, returns False. Otherwise, returns True.
Parameters:
Required/ Repeating
Notes
Now()
Description:
The Now function returns a string representing the current UTC DateTime in the format M/d/yyyy h:mm:ss tt.
Example:Now()
Example value returned 7/2/2021 3:33:38 PM
NumFromDate
Function:
NumFromDate(value)
Description:
The NumFromDate function converts a DateTime value to Active Directory format that is required to set attributes like accountExpires. Use this function to convert DateTime values received from cloud HR apps like Workday and SuccessFactors to their equivalent AD representation.
Parameters:
Required/ Repeating
Notes
Example:
Workday example: Assuming you want to map the attribute ContractEndDate from Workday, which is in the format 2020-12-31-08:00 to accountExpires field in AD, here's how you can use this function and change the timezone offset to match your locale.
NumFromDate(Join("", FormatDateTime([ContractEndDate], ,"yyyy-MM-ddzzz", "yyyy-MM-dd"), " 23:59:59-08:00"))
SuccessFactors example: Assuming you want to map the attribute endDate from SuccessFactors, which is in the format M/d/yyyy hh:mm:ss tt to accountExpires field in AD, here's how you can use this function and change the time zone offset to match your locale.
NumFromDate(Join("",FormatDateTime([endDate], ,"M/d/yyyy hh:mm:ss tt","yyyy-MM-dd")," 23:59:59-08:00"))
PCase
Function:
PCase(source, wordSeparators)
Description:
The PCase function converts the first character of each word in a string to upper case, and all other characters are converted to lower case.
Parameters:
Required/Optional
Notes
Remarks:
If the wordSeparators parameter isn't specified, then PCase internally invokes the .NET function ToTitleCase to convert the source string to proper case. The .NET function ToTitleCase supports a comprehensive set of the Unicode character categories as word separators.
Space character
New line character
Control characters like CRLF
Format control characters
ConnectorPunctuation characters like underscore
DashPunctuation characters like dash and hyphen (including characters such En Dash, Em Dash, double hyphen, and so on)
OpenPunctuation and ClosePunctuation characters that occur in pairs like parenthesis, curly bracket, angle bracket, and so on.
InitialQuotePunctuation and FinalQuotePunctuation characters like single quotes, double quotes, and angular quotes.
OtherPunctuation characters like exclamation mark, number sign, percent sign, ampersand, asterisk, comma, full stop, colon, semi-colon, and so on.
MathSymbol characters like plus sign, less-than and greater-than sign, vertical line, tilde, equals sign, and so on.
CurrencySymbol characters like dollar sign, cent sign, pound sign, euro sign, and so on.
ModifierSymbol characters like macron, accents, arrow heads, and so on.
OtherSymbol characters like copyright sign, degree sign, registered sign, and so on.
If the wordSeparators parameter is specified, then PCase only uses the characters specified as word separators.
Example:
Let's say you're sourcing the attributes firstName and lastName from SAP SuccessFactors and in HR both these attributes are in upper-case. Using the PCase function, you can convert the name to proper case as shown here.
Expression
Input
Output
Notes
firstName = "PABLO GONSALVES (SECOND)"
"Pablo Gonsalves (Second)"
As the wordSeparators parameter isn't specified, the PCase function uses the default word separators character set.
PCase([lastName]," '-")lastName = "PINTO-DE'SILVA"
"Pinto-De'Silva"
The PCase function uses characters in the wordSeparators parameter to identify words and transform them to proper case.
PCase(Join(" ",[firstName],[lastName]))firstName = GREGORY, lastName = "JAMES"
"Gregory James"
You can nest the Join function within PCase. As the wordSeparators parameter isn't specified, the PCase function uses the default word separators character set.
Description:
The RandomString function generates a random string based on the conditions specified. Characters allowed can be identified here.
Parameters:
Required/ Repeating
Notes
Required
Number
Total length of the random string. This should be greater than or equal to the sum of MinimumNumbers, MinimumSpecialCharacters, and MinimumCapital. 256 characters max.
MinimumNumbers
Required
Number
Minimum numbers in the random string.
MinimumSpecialCharacters
Required
Number
Minimum number of special characters.

Required
Number
Minimum number of lower case letters in the random string.
CharactersToAvoid
Optional
String
Characters to be excluded when generating the random string.
Example 1: - Generate a random string without special character restrictions:
RandomString(6,3,0,0,3)
Generates a random string with 6 characters. The string contains 3 numbers and 3 lower case characters (1a73qt).
Example 2: - Generate a random string with special character restrictions:
RandomString(10,2,2,2,1,"?,")
Generates a random string with 10 characters. The string contains at least 2 numbers, 2 special characters, 2 capital letters, 1 lower case letter and excludes the characters "?" and "," (1@!2BaRg53).
Redact
Function:
Redact()
Description:
The Redact function replaces the attribute value with the string literal "[Redact]" in the provisioning logs.
Parameters:
Required/ Repeating
Notes
Example 1: Redact an attribute:
Redact([userPrincipalName])
Removes the userPrincipalName from the provisioning logs.
Example 2: Redact a string:
Redact("StringToBeRedacted")
Removes a constant string from the provisioning logs.
Example 3: Redact a random string:
Redact(RandomString(6,3,0,0,3))
Removes the random string from the provisioning logs.
RemoveDuplicates
Function:
RemoveDuplicates(attribute)
Description:
The RemoveDuplicates function takes a multi-valued string and make sure each value is unique.
Parameters:
Required/ Repeating
Notes
Example:RemoveDuplicates([proxyAddresses])
Returns a sanitized proxyAddress attribute where all duplicate values are removed.
When regexPattern, regexGroupName, replacementValue are provided:
The function applies the regexPattern to the source string and replaces all values matching regexGroupName with replacementValue
When regexPattern, regexGroupName, replacementAttributeName are provided:
If source has a value, source is returned
If source has no value, the function applies the regexPattern to the replacementAttributeName and returns the value matching regexGroupName
Parameters:
Required/ Repeating
Notes
Optional
String
Regex pattern for the value to be replaced in source. When replacementAttributeName is used, the regexPattern is applied to extract a value from replacementAttributeName.
regexGroupName
Optional
String
Name of the group inside regexPattern. When named replacementAttributeName is used, we extract the value of the named regex group from the replacementAttributeName and return it as the replacement value.
replacementValue
Optional
String
New value to replace old one with.
replacementAttributeName
Optional
String
Name of the attribute to be used for replacement value
template
Optional
String
When template value is provided, we look for oldValue inside the template and replace it with source value.
Replace characters using a regular expression
Example 1: Using oldValue and replacementValue to replace the entire source string with another string.
Let's say your HR system has an attribute BusinessTitle. As part of recent job title changes, your company wants to update anyone with the business title "Product Developer" to "Software Engineer".
Then in this case, you can use the following expression in your attribute mapping.
Example 2: Using oldValue and template to insert the source string into another templatized string.
The parameter oldValue is a misnomer in this scenario. It's actually the value that gets replaced.
Let's say you want to always generate login ID in the format <username>@contoso.com. There's a source attribute called UserID and you want that value to be used for the <username> portion of the login ID.
Then in this case, you can use the following expression in your attribute mapping.
Example 3: Using regexPattern and replacementValue to extract a portion of the source string and replace it with an empty string or a custom value built using regex patterns or regex group names.
Let's say you have a source attribute telephoneNumber that has components country code and phone number separated by a space character. For example, +91 9998887777
Then in this case, you can use the following expression in your attribute mapping to extract the 10 digit phone number.
You can also use this pattern to remove characters and collapse a string.
For example, the following expression removes parenthesis, dashes and space characters in the mobile number string and returns only digits.
Replace([mobile], , "[()\\s-]+", , "", , )
source:[mobile] = "+1 (999) 888-7777"
regexPattern: "[()\\s-]+"
replacementValue: "" (empty string)
Expression output: 19998887777
Example 4: Using regexPattern, regexGroupName and replacementValue to extract a portion of the source string and replace it with another literal value or empty string.
Let's say your source system has an attribute AddressLineData with two components street number and street name. As part of a recent move, let's say the street number of the address changed, and you want to update only the street number portion of the address line.
Then in this case, you can use the following expression in your attribute mapping to extract the street number.
Example 5: Using regexPattern, regexGroupName and replacementAttributeName to handle scenarios when the source attribute is empty or doesn't have a value.
Let's say your source system has an attribute telephoneNumber. If telephoneNumber is empty, you want to extract the 10 digits of the mobile number attribute.
Then in this case, you can use the following expression in your attribute mapping.
Description:
Requires a minimum of two arguments, which are unique value generation rules defined using expressions. The function evaluates each rule and then checks the value generated for uniqueness in the target app/directory. The first unique value found is the one returned. If all of the values already exist in the target, the entry is escrowed, and the reason gets logged in the audit logs. There's no upper bound to the number of arguments that can be provided.
This function must be at the top-level and can't be nested.
This function can't be applied to attributes that have a matching precedence.
This function is only meant to be used for entry creations. When using it with an attribute, set the Apply Mapping property to Only during object creation.
This function is currently supported for use with these applications:
Workday to Active Directory User Provisioning
SuccessFactors to Active Directory User Provisioning
API-driven provisioning to on-premises Active Directory
SelectUniqueValue isn't supported for use with other provisioning applications.
The LDAP search that SelectUniqueValue function performs in on-premises Active Directory doesn't escape special characters like diacritics. If you pass a string like "Jéssica Smith" that contains a special character, you'll encounter processing errors. Nest the NormalizeDiacritics function as shown in this example to normalize special characters.
Parameters:
Required/ Repeating
Notes
Generate unique value for userPrincipalName (UPN) attribute
Example: Based on the user's first name, middle name and last name, you need to generate a value for the UPN attribute and check for its uniqueness in the target AD directory before assigning the value to the UPN attribute.
Description:
Returns a single appRoleAssignment from the list of all appRoleAssignments assigned to a user for a given application. This function is required to convert the appRoleAssignments object into a single role name string. The best practice is to ensure only one appRoleAssignment is assigned to one user at a time. This function isn't supported in scenarios where users have multiple app role assignments.
Description:
Splits a string into a multi-valued array, using the specified delimiter character.
Parameters:
Required/ Repeating
Notes
Split a string into a multi-valued array
Example: You need to take a comma-delimited list of strings, and split them into an array that can be plugged into a multi-value attribute like Salesforce's PermissionSets attribute. In this example, a list of permission sets are populated in extensionAttribute5 in Microsoft Entra ID.
Description:
When source value matches a key, returns value for that key. If source value doesn't match any keys, returns defaultValue. Key and value parameters must always come in pairs. The function always expects an even number of parameters. The function shouldn't be used for referential attributes such as manager.
Switch function performs a case-sensitive string comparison of the source and key values. If you'd like to perform a case-insensitive comparison, normalize the source string before comparison using a nested ToLower function and ensure that all key strings use lowercase.
Example: Switch(ToLower([statusFlag]), "0", "true", "1", "false", "0"). In this example, the source attribute statusFlag may have values ("True" / "true" / "TRUE"). However, the Switch function always converts it to lowercase string "true" before comparison with key parameters.
Caution
For the source parameter, do not use the nested functions IsPresent, IsNull or IsNullOrEmpty. Instead use a literal empty string as one of the key values.
Example: Switch([statusFlag], "Default Value", "true", "1", "", "0"). In this example, if the source attribute statusFlag is empty, the Switch function returns the value 0.
Parameters:
Required/ Repeating
Notes
Optional
String
Default value to be used when source doesn't match any keys. Can be empty string ("").
Required
String
Key to compare source value with.
value
Required
String
Replacement value for the source matching the key.
Replace a value based on predefined set of options
Example: Define the time zone of the user based on the state code stored in Microsoft Entra ID.
If the state code doesn't match any of the predefined options, use default value of "Australia/Sydney".
Description:
Takes a source string value and converts it to lower case using the culture rules that are specified. If there's no culture info specified, then it uses Invariant culture.
If you would like to set existing values in the target system to lower case, update the schema for your target application and set the property caseExact to 'true' for the attribute that you're interested in.
Parameters:
Required/ Repeating
Notes
Optional
String
The format for the culture name based on RFC 4646 is languagecode2-country/regioncode2, where languagecode2 is the two-letter language code and country/regioncode2 is the two-letter subculture code. Examples include ja-JP for Japanese (Japan) and en-US for English (United States). In cases where a two-letter language code isn't available, a three-letter code derived from ISO 639-2 is used.
Convert generated userPrincipalName (UPN) value to lower case
Example: You would like to generate the UPN value by concatenating the PreferredFirstName and PreferredLastName source fields and converting all characters to lower case.
Description:
Takes a source string value and converts it to upper case using the culture rules that are specified. If there's no culture info specified, then it uses Invariant culture.
If you want to set existing values in the target system to upper case, update the schema for your target application and set the property caseExact to 'true' for the attribute that you're interested in.
Parameters:
Required/ Repeating
Notes
Optional
String

Word(String,WordNumber,Delimiters)
Description:
The Word function returns a word contained within a string, based on parameters describing the delimiters to use and the word number to return. Each string of characters in string separated by the one of the characters in delimiters are identified as words:
If number < 1, returns empty string.
If string is null, returns empty string.
If string contains less than number words, or string doesn't contain any words identified by delimiters, an empty string is returned.
Parameters:
Required/ Repeating
Notes
Word("The quick brown fox",3," ")
Returns "brown".
Word("This,string!has&many separators",3,",!&#")
Returns "has".
