Replacing Microsoft Office for free: text, spreadsheets, slides
Replacing Office starts with knowing what you need: a complete suite, or just a word processor or a spreadsheet. Each need only lists tools whose feature is described by their authors, with the source and the date it was read.
Data as of 6 November 2026 · 30 resources selected, all published after their official site and free status were verified at a reliable source.
Choose by need
Only tools whose capability is established under the same rules as their listings are shown here: a page from their authors (website, repository, Steam page), an app catalogue listing (Flathub, F-Droid, Winget, Debian package, SourceForge) or a Wikipedia article, read automatically; the source and reading date are shown for each.
Complete office suite
Word processing, spreadsheets and presentations in one package, like Microsoft Office.

Good to know
“Format mentioned” means the tool’s documentation mentions that format, not that the layout of a complex document will be kept identical: check your important files.
An online suite stores your documents on its publisher’s servers: read its terms before uploading confidential documents.
How this list is built
Order: most complete free offer first (no strings, then with conditions, then limited free version), then a popularity index computed from public signals (installs in official catalogues, repository stars, presence in several sources). No position can be bought.
