Hi Team, Power automate
I just wanted to add a column to my excel file.
Note: my excel file doesn't have any tables and excel file has headers first later rows and columns.
I have tried with add a key column but it didn't worked due to excel doesn't have table.

Would you share your flow definition and failling exception?
