What is a .ODF file?
Everything worth knowing about OpenDocument Formula files.
An .ODF file is an OpenDocument Formula document developed by Oracle. It contains mathematical data and equations used within office productivity suites.

Is my .ODF file uploaded anywhere?
No. Your .ODF file is read and converted for you. The first time, a small open-source conversion component is downloaded and then cached.
Why does my older .ODF file look plain?
Some older word-processor files keep their formatting in a complex binary layout. The viewer shows all the text and tables reliably; richer formatting for those files is coming with server-side conversion.
Are macros in a .ODF file safe here?
Yes. The viewer never runs macros. It only reads the document text, styles and images, and tells you when a file contains macros.
Can I edit my .ODF file?
This is a viewer. You can copy the text or save it as HTML/TXT and edit it elsewhere. An online editor is on our roadmap.
It says my .ODF file is something else. Why?
We check the file's signature, not just its name. If a file was renamed, the viewer tells you what it really is and which tool opens it.
