Attach Excel file to Sharepoint list not working

Hi there,


I have a Canvas app and in there a form linked to a sharepoint list. I would like to use it to attach files to the sharepoint list, so I created the SubmitForm button.


This works totally fine with all types of documents (PDF etc.), but doesn't work with Excel files (XLSX, XLSM etc.).


Is there any way I could fix this?

@JohnTeresa ,

I assume you are using a standard Attachment Control? There is no reason Excel files will not attach except maybe they are too big - what size are they?
