## Create a list of users who have a user role {#array-string-data__example_dj4_3yt_rbc}

This example uses a custom action to generate a list of users who have a specific user role. To create the custom action to generate an array of strings, see [Create a custom action to generate an array of strings from a list of records](https://servicenow-prod.fluidtopics.net/OiaxgM0M6vljWFTWGNngjg "Generate an array of strings from a list of User Role records. Learn how to use a Script step to iterate through a list of records.").  
In this example, the users array contains three users who have the admin role.

    {
        "users": [
            "System Administrator",
            "Rob Phillips",
            "Fred Luddy"
        ]
    }
