Hi @Sand_Kob , it looks to me that you want the other way around, that is move multiple columns into multiple rows…
Can you show us what the real column names look like? I mean, you can’t have 2 columns with the same name. You can’t have 2 columns called “User name” and you can’t have 2 columns called “Profile”.
You can look into the Transpose node or the Pivoting node for moving columns to rows and rows to columns.
