I am trying to grade assignments offline. I am able to download and open the file in Excel and add the grades under the grade column and then save as a csv file.
However, when I upload the modified file, I get the message "No modified grades found in uploaded worksheet." I haven't made any other modifications to the grades, but clicking on the box that allows changes to be made doesn't make any difference either.
What am I doing wrong?
I am using 2.6.2+ and an older version of Excel, if that helps.
