ONLYOFFICE vs Microsoft Excel Comments
It doesen't support xlsm and xlsb files

- ONLYOFFICE is Free and Open Source
- ONLYOFFICE is Privacy focused










Very easy to use and has a familiar interface. It’s much better than LibreOffice for both compatibility with MS Excel and its overall design. All of the formulas that I use in MS Excel work in ONLYOFFICE.
