Writing expressions for attribute mappings in Microsoft Entra ID
When you configure cloud sync, one of the types of attribute mappings that you can specify is an expression mapping.
The expression mapping allows you to customize attributes using a script-like expression. This allows you to transform the on-premises data into a new or different value. For example, you may want to combine two attributes into a single attribute because this single attribute is used by one of your cloud applications.
The following document will cover the script-like expressions that are used to transform the data. This is only part of the process. Next you will need to use this expression and place it in a web request to your tenant. For more information on that see Transformations
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 may 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\""

Description:
Join() is similar to Append(), except that it can combine multiple source string values into a single string, and each value will be separated by a separator string.
If one of the source values is a multi-value attribute, then every value in that attribute will be joined together, separated by the separator value.
Parameters:
| Name | Required/ Repeating | Type | Notes |
|---|---|---|---|
| separator | Required | String | String used to separate source values when they are 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. |

- 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.
Example:
Left("John Doe", 3)
Returns Joh.
Mid
Function:
Mid(source, start, length)
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:
| Name | Required/ Repeating | Type | Notes |

When oldValue and replacementValue are provided:
- Replaces all occurrences of oldValue in the source with replacementValue
When oldValue and template are provided:
- Replaces all occurrences of the oldValue in the template with the source value
When regexPattern and replacementValue are provided:
- The function applies the regexPattern to the source string and you can use the regex group names to construct the string for replacementValue
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 no value, source is returned
- If source has a value, the function applies the regexPattern to the source string and replaces all values matching regexGroupName with the value associated with replacementAttributeName

SelectUniqueValue
Function:
SelectUniqueValue(uniqueValueRule1, uniqueValueRule2, uniqueValueRule3, …)
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 will be the one returned. If all of the values already exist in the target, the entry will get escrowed and the reason gets logged in the audit logs. There is no upper bound to the number of arguments that can be provided.
Note
- This is a top-level function, it cannot be nested.
- This function cannot be applied to attributes that have a matching precedence.

Examples
Strip known domain name
You need to strip a known domain name from a user’s email to obtain a user name.
For example, if the domain is "contoso.com", then you could use the following expression:
Expression:
Replace([mail], "@contoso.com", , ,"", ,)
Sample input / output:
- INPUT (mail): "john.doe@contoso.com"
- OUTPUT: "john.doe"

Convert generated userPrincipalName (UPN) value to lower case
In the example below, the UPN value is generated by concatenating the PreferredFirstName and PreferredLastName source fields and the ToLower function operates on the generated string to convert all characters to lower case.
ToLower(Join("@", NormalizeDiacritics(StripSpaces(Join(".", [PreferredFirstName], [PreferredLastName]))), "contoso.com"))
Sample input/output:
- INPUT (PreferredFirstName): "John"
- INPUT (PreferredLastName): "Smith"
- OUTPUT: "john.smith@contoso.com"
Generate unique value for userPrincipalName (UPN) attribute
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.
Expression:
SelectUniqueValue(
Join("@", NormalizeDiacritics(StripSpaces(Join(".", [PreferredFirstName], [PreferredLastName]))), "contoso.com"),
Join("@", NormalizeDiacritics(StripSpaces(Join(".", Mid([PreferredFirstName], 1, 1), [PreferredLastName]))), "contoso.com"),
Join("@", NormalizeDiacritics(StripSpaces(Join(".", Mid([PreferredFirstName], 1, 2), [PreferredLastName]))), "contoso.com")
)
Sample input/output:
- INPUT (PreferredFirstName): "John"
- INPUT (PreferredLastName): "Smith"
- OUTPUT: "John.Smith@contoso.com" if UPN value of John.Smith@contoso.com doesn't already exist in the directory
- OUTPUT: "J.Smith@contoso.com" if UPN value of John.Smith@contoso.com already exists in the directory
- OUTPUT: "Jo.Smith@contoso.com" if the above two UPN values already exist in the directory
