I have a sheet to track workers roles however, some people are listed multiple times as they have multiple roles because depending on the project their role is different. I was wondering if there was a way to use an Index(match( to either concat all of their roles in 1 formula without the use of a helper column. My current formula can only produce the first role in the list =IFERROR(INDEX(Role$3:Role$72, MATCH([Worker Name]@row, Name$3:Name$72, 0)), "-")
Ex
John PM
Tina Engineer
John Engineer
For John I would only be able to pull PM as it comes first on the list. I would like to have it show for John PM,Engineer
