I am trying to read an excel file with several rows and columns but it has an error “Value cannot be null” “Parameter Name: String”
When I try to read another excel file the error does not happen.
Do I have to do any treatment before reading excel for this error not to happen and being able to read the data in the spreadsheet? I don’t have excel installed on the machine.
The robot is reading all the xlsx files that are in the folder and when saving to another xlsx file it is saving empty. The Read Range output Data Table variable is coming empty.
Attached is the xaml file with the part of the robot that does this.

I will be very grateful if anyone can help me.
