I am not sure if spaces in file names are supported. => Maybe the CSV reading fails. That would explain why in line11 gives the “!COL1” not supported" error you mentioned.
to repeat ForEachRow of the CSV.
3 options:
(1) Use the Loop button
(2) Use WHILE (see DemoCsvReadWithWhile that comes with the RPA software)
(3) Instead of csvRead use csvReadArray
and read the complete CSV file at once, see also How to mark a row in a CSV line as processed?
