Hi. With 2nd approach, i could able to solve it. I chose the data type for variable as System.String and after assigning the code to this variable, i used For Each activity and then in Use Excel File activity i chose Excel file as currentText. and it worked.
Thank you.
Btw, I’ve found another solution before this. I changed the outline for For Each File in Folder activity, so I didn’t use open Daily Report file again and didn’t get any error. You can check ex and new outlines in attachment.
