Splitting comma-separated string and returning a specific section

[ChadVKealey]

User Display Names in our environment are in the form of LastName,FirstName (don't ask). What I want to do is extract the FirstName (to include in an email). There are two ways I can think of to do this, but I'm not having any luck getting the syntax right on either of them:

• Use the "split" expression to put the two names into a list/array, then retrieve item [1] from the array (assuming they actually went with the industry standard and start the array at item [0]). Downside of this is that (I think) it would require two variables (one array and one string)
• Use some form the the "substring" expression. I used this a bunch back in the day with SPD 2010 for custom XSLT views and formulas, but I'm kind of rusty. Also, in that context, there was a more specific "substring-after" operator, so I could say "substring-after,','" (or something like that) to return the substring after the comma (which is exactly what I need).

There are probably several other ways to do this that I'm overlooking, but I'm running out of patience trying to figure this out on my own. Any guidance or help would be appreciated.

use the below function to split and get the first name. In this example i am using the output of the Get user profile action under Office 365 users.

           last(split(body('Get_user_profile_(V2)')?['displayName'],','))

Logic is to split the string delimited by ',' into an array and then fetch the last element of the array

Hi @ChadVKealey，

I you would like to get the FirstName from the User Display Name,

As @Anonymous said, you could use expression below to achieve your needs:

last(split(body('Get_user_profile_(V2)')?['displayName'],','))

Also you could take a try with expression below:

first(skip(split(body('Get_user_profile_(V2)')?['displayName'],','),1))

Please take a try on your side and let me know if your problem could be solved.

Best regards,

Alice
