Apache OpenOffice – Free Open Source Office Suite

What is OpenOffice.org?

Apache OpenOffice (formerly OpenOffice.org) is a free, open-source office productivity suite that provides a complete alternative to Microsoft Office. Originally released in 2000 and later donated to the Apache Software Foundation in 2011, OpenOffice has been downloaded over 300 million times, making it one of the most popular open-source applications in history.
