Apache OpenOffice

OpenOffice.org is the leading open-source office software suite for word processing, spreadsheets, presentations, graphics and databases. The application is available in many languages and works on all common computers.

Great software
OpenOffice.org is the result of over twenty years' software engineering. Designed from the start as a single piece of software, it has a consistency other products cannot match. A completely open development process means that anyone can report bugs, request new features, or enhance the software.
