Gnumeric
A lightweight open-source spreadsheet built for speed and accuracy.
Gnumeric is a free, open-source spreadsheet application with source code available under the GNU GPL. The project emphasizes quick startup, responsive handling of large workbooks, and reliable results from its built-in functions and analysis tools.
Why it stands out
- Calculation accuracy is a stated project focus and is supported by outside researcher findings cited by the project.
- Designed as a standalone spreadsheet rather than a full office-suite component, keeping the tool focused.
- Source code is freely available under GPL version 2 or 3 terms.
- Recent release news indicates the project is still maintained.
Good to know
- Focused on spreadsheets only, not a full office suite with word processing or presentations.
- Requires installing a desktop application rather than working as a browser-based collaborative spreadsheet.
- Support resources are community/project channels such as a manual, FAQ, mailing list, and bug tracker rather than commercial support.
