The following error occurs when ‘write range’ is set as above.
@iron_helmet Are you able to Output the Datatable in a Message Box using Output Datatable Activity?
Write range to new file and check whether you get the error or not?
In file path just give “TMA_Tuning1.xlsx” and check? and make sure that Filter_H2 contains data.
There were too many sheets in the original Excel file so there was an error. I cleaned up the original Excel file sheet and the error disappeared.
