I have the write range activity (workbook) that would write a dtvalue in excel. That specific activity produces the write range error: bad file name or number and i couldn’t find any discussion related to it. I already checked the details and they are all correct so I’m not sure why there’s an error.
@bbhyuns Can you use Write Line and Check the Value of the argument that you get. Also try Hard coding the value and check if you are able to get it working.
I had faced this issue. Can you check the full path that you pass as a filename. Sometimes , when we pass the full path , there could have been a missing \ back slash.
