Expression to convert Multiple Managed Metadata Column to comma separated string

Hello,

 

i have a SharePoint managed metadata column called "Scope" (Allow multi select). Where the user can select multiple scopes for an document like IT, HR or Operations.

In a flow I want to save them in another column as string e.g. "IT, HR"

 

First Idea, expression:

 

 

 

 

join(triggerBody()?['Scope']?['Label'],', ')

 

 

 

 

But this results in an error: "Array elements can only be selected with an integer index."

 

Do you have any solution for this?

 

Best regards,

Jonas

Hi @jesser,

 

You can use a select action to collect the label values. After that you can use a join function.

 

 @tom_riha has a nice blogpost about that approach: https://tomriha.com/how-to-convert-array-to-a-string-in-power-automate/

 

In your case it could be a setup like this:
