Apache OpenOffice, commonly known as OpenOffice.org, OOo or OpenOffice, is an open-source office productivity software suite whose main components are for word processing, spreadsheets, presentations, graphics, and databases. OpenOffice is available for a number of different computer operating systems, is distributed as free software and is written using its own GUI toolkit. It supports the ISO/IEC standard OpenDocument Format (ODF) for data interchange as its default file format, as well as Microsoft Office formats among others. As of June 2011, OpenOffice.org supports over 120 languages.[2] As free software, users are free to download, modify, use and distribute OpenOffice.org.

OpenOffice.org originated as StarOffice, an office suite developed by StarDivision and acquired by Sun Microsystems in August 1999. The source code of the suite was released in July 2000 with the aim of providing a free and open alternative to Microsoft Office. OpenOffice.org was an open-source version of the StarOffice suite, with development sponsored primarily by Sun Microsystems. After acquiring Sun in 2010, Oracle Corporation briefly continued developing OpenOffice.org and StarOffice, which it renamed Oracle Open Office, but in 2011 the firm stopped supporting commercial development[8] and contributed the suite to the Apache Incubator to become a project of the Apache Software Foundation. As of December 2011, the project is officially known as Apache OpenOffice. can collaborate with you to find solutions to complex issues.
