    When can we upload .xlsx files?

    Asked by amyhalpin on October 21, 2013 at 08:02 PM

    When users submit files, they get an error message that doesn't allow them to submit if their document is a .xlsx file (the newer Excel version). Can this be fixed? Quite a lot of people are using the new version.

    Thank you!

    Hello, do make sure you have the extension available,

    You can do this by clicking on the extension button (while you have the file upload field selected). Then add the neccesary extensions to the list.



    Do let us know if you need further support, thank you.
