Collabora Office

Collabora Office brings a full office suite to Android, combining text editing, spreadsheets and presentations into a single mobile productivity app that preserves desktop compatibility. The app uses the same core engine as the LibreOffice desktop suite to open, edit and save documents in Open Document formats and common Microsoft Office formats, helping you work on reports, spreadsheets and slides while maintaining layout and formatting. Collabora Office is actively developed and welcomes user feedback to improve stability and support for mobile workflows.

Key Features

Collabora Office combines a word processor, spreadsheet and presentation program in one package for on-device editing. The app provides full support for Open Document Format and popular Microsoft Office file types, including .odt, .odp, .ods, .docx, .pptx and .xlsx. By sharing the LibreOffice core engine, Collabora Office delivers desktop-like fidelity for reading, editing and saving documents and aims to preserve complex layouts on mobile screens.

Advantages

Collabora Office offers wide format compatibility to reduce conversion issues between desktop and mobile, and it provides familiar desktop-grade rendering and editing thanks to the shared engine. The app enables meaningful editing of text documents, spreadsheets and presentations while away from a PC, and its open-source licensing supports transparency and community-driven improvements.

Disadvantages

The project is under active development, so users may encounter occasional bugs or features that differ from the desktop experience. Bug reports and diagnostics submitted to the public issue tracker are visible to others, which is intended to help development but may expose reported details.

Development Team

Collabora Office Android support has been developed since 2012 by engineers Tor Lillqvist, Tomaž Vajngerl, Michael Meeks, Miklos Vajna, Jan Holešovský, Mert Tümer and Rashesh Padia, with additional contributions from students during summer development projects.
