Mac Numbers fails to export to Google Sheets
I'm collaboratively working with a group of people who don't have Apple Macs. We're using Google Sheets to share spreadsheets.
However, Numbers 5.0 doesn't seem to produce an excel spreadsheet that is compatible with Google Sheets. I've tried both .xlsx and .xls but Google comes up with "unable to convert document".
I transferred the file to my Raspberry Pi and used LibreOffice Calc and saved it as a .xslx and Google Sheets was able to convert it but this seems a little OTT.
Anybody any ideas?
