Quadratic, Team
Technical teams want tools that are open and transparent. As the world's most popular interface for data, the spreadsheet has surprisingly few options for open source and open access software. Here is a list of some of the top open source spreadsheets.
Top open source spreadsheets
LibreOffice Calc
- Introduced in 2010
- License: Mozilla Public License Version 2.0
LibreOffice is one of the most used open source office suites. Calc is Libre Office's spreadsheet product. Well-known throughout the open source community, LibreOffice was forked from OpenOffice, which was a fork of StarOffice. When Sun Microsystems acquired StarOffice, OpenOffice was the open source fork that continued as StarOffice became closed source and internally maintained by Sun. LibreOffice's fork from OpenOffice was initiated in 2010.
Apache OpenOffice
- Introduced in 2002
- License: Apache 2.0
As mentioned above, OpenOffice was a successor project to StarOffice. Eventually, however, OpenOffice was donated to the Apache Software Foundation and has been Apache OpenOffice ever since. Like most of the products in this list, you can freely download OpenOffice to your machine without limitation.
Apache OpenOffice is licensed under the Apache 2.0 License.
Gnumeric
- Introduced in 2001
- License: GNU General Public License v2.0 or v3.0
Gnumeric was first released all the way back in 2001! Boasting free, fast, and accurate software, Gnumeric is a favorite of many old-school Linux users.
OnlyOffice
- Introduced in 2012
- License: GNU Affero General Public License v3.0
OnlyOffice Spreadsheet is an open-source spreadsheet that originated as an open-source office suite alternative. One of its more interesting claims to fame is being the first HTML-5-based document editor on the market, proudly announced back in 2012, two years before HTML-5 was marked as recommended software by W3C.
Quadratic
