Meta: How can I attach an Excel file to a post?
I have a question which would be easier to ask if I could attach the Excel file. If I drag and drop it onto the window an error appears saying that .xlsx files are not supported. Can I attach the file in some other way?
aaltomani If you don't see this option at the bottom of your post yet
you need to share the file via Onedrive, Dropbox or some similar file sharing facility.
