Yes, OnlyOffice keeps files in standard Microsoft Office formats like docx, xlsx, and pptx, so documents open correctly when shared with people still using Microsoft Office. This compatibility means collaborators do not run into formatting issues when exchanging files, removing one of the biggest concerns people have before switching away from Microsoft 365. _Comparing office suite compatibility before switching tools is easier when you follow ongoing coverage on daily.dev._ ### What features does OnlyOffice offer compared to Microsoft Office? OnlyOffice provides word processing, spreadsheet, and presentation tools similar to Word, Excel, and PowerPoint, combined into a single free application. It has a tabbed interface with multiple window options, remains lightweight despite being feature-rich, and covers everyday tasks like writing, spreadsheet tracking, and presentations without requiring separate paid apps. _Developers evaluating free versus paid productivity tools can keep tabs on comparisons like this via daily.dev._ ## Similar posts on daily.dev - [I found a free Microsoft Word alternative that doesn't compromise on features](https://daily.dev/posts/i-found-a-free-microsoft-word-alternative-that-doesn-t-compromise-on-features-lwi3rfsww) · XDA Developers · 0 upvotes · 0 comments - [Your 2026 quick guide to free Office alternatives](https://daily.dev/posts/your-2026-quick-guide-to-free-office-alternatives-s6laz6ap3) · All Things Open · 0 upvotes · 0 comments - [I found a free, browser-based Microsoft Office alternative and it made me forget about the original](https://daily.dev/posts/i-found-a-free-browser-based-microsoft-office-alternative-and-it-made-me-forget-about-the-original-cijupbkcl) · XDA Developers · 0 upvotes · 0 comments - [I built my own Microsoft 365 with free open-source apps and my productivity didn’t drop a bit](https://daily.dev/posts/i-built-my-own-microsoft-365-with-free-open-source-apps-and-my-productivity-didn-t-drop-a-bit-lwnecjgkv) · XDA Developers · 2 upvotes · 0 comments - [LibreOffice vs ONLYOFFICE - Which One Is Right For You?](https://daily.dev/posts/libreoffice-vs-onlyoffice---which-one-is-right-for-you--8dvajy04a) · It's Foss · 4 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#microsoft](https://daily.dev/tags/microsoft), [#productivity](https://daily.dev/tags/productivity) [View this post on daily.dev](https://daily.dev/posts/this-one-free-open-source-tool-replaced-three-paid-apps-i-d-used-for-years-r0boaqngt) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"This one free open-source tool replaced three paid apps I'd used for years","url":"https://daily.dev/posts/this-one-free-open-source-tool-replaced-three-paid-apps-i-d-used-for-years-r0boaqngt","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/this-one-free-open-source-tool-replaced-three-paid-apps-i-d-used-for-years-r0boaqngt"},"datePublished":"2026-08-02T17:00:42.313Z","dateModified":"2026-09-14T09:30:31.992Z","description":"A writer shares their experience replacing Microsoft 365 with OnlyOffice, a free open-source office suite.
