Create Loop for each Excel File export a separate CSV

Thank you i resolved this but I have another problem.
I’m downloading the excel files and I’m using the “Wait for Download” Activity. After that I’m using the Use Excel File Activity and the excel file is the Downloaded file .Tostring. The problem I have is that sometimes when UIPath opens the file this is what happens. Note that this is a loop so it downlaods multiple excel. Is there a way to fix this?
