The best European office suite overall is LibreOffice (Germany): free, open source and backed by a non-profit foundation in Berlin, with apps for documents, spreadsheets, presentations, drawings and databases. For files that stay in DOCX and XLSX, choose SoftMaker Office (Germany); for a cloud suite like Microsoft 365, Infomaniak kSuite (Switzerland).
This is the overview of every European office suite I would recommend, with one line on who each one is for. Some are desktop apps that keep your files on your own computer; others are online editors for co-writing in the browser. If you are leaving a specific product, the deeper comparison is in Best European alternatives to Microsoft Office. All prices and facts were checked on the vendors’ own pages on 25 October 2026.

How I chose the best European office suites
I compared ten office suites from the EU, Switzerland and the UK and kept eight. Each one was checked on the same five points: compatibility with Microsoft’s DOCX, XLSX and PPTX formats, features (desktop and mobile apps, presentations, co-editing), jurisdiction, ownership and hosting, price for a household and a small team, and user ratings on Trustpilot. Full desktop suites rank above browser-only editors. WPS Office (China) and Zoho (India) are not listed because they are not European, and Euro-Office is covered under Nextcloud Office, where it runs.
