Hi,
it looks like your data also makes sense if you use the values of Col0 as columns and transpose the table. Could you use the RowID node to make column Col0 into a RowID, then Transpose the table so they become columns and then use a String Manipulation node to generate your desired result?
Kind regards
Alexander
thanks for your help. Your post reminded me to give RowID and Transpose a second try and it worked out. I think Iām on a good way to get my Workflow going to produce the desired outcome.
