Häufige Fragen

Is the price difference from Office 2021 to 2024 worth it?

For 3+ years of use and if you want security updates: yes. Functionally, the differences are minor for standard users (Python in Excel is the biggest new feature). If you mainly use Word and standard Excel: 2021 is enough.

Are .docx and .xlsx files compatible between 2021 and 2024?

Yes, 100% in both directions. Also with 2019, 2016 and the Mac version.

Can I upgrade from Office 2021 to 2024?

Not directly with the same license. Office 2024 is a new perpetual license. You purchase Office 2024 anew and install it. Your files remain unchanged.
