OpenOffice.org 3 is the leading open-source office software suite for word processing, spreadsheets, presentations, graphics, databases and more. It is available in many languages and works on all common computers.

Great software

OpenOffice.org 3 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.

Easy to use

OpenOffice.org 3 is easy to learn, and if you’re already using another office software package, you’ll take to OpenOffice.org 3 straight away. Our world-wide native-language community means that OpenOffice.org 3 is probably available and supported in your own language.

… And it’s free

Best of all, OpenOffice.org 3 can be downloaded and used entirely free of any licence fees. OpenOffice.org 3 is released under the LGPL licence. This means you may use it for any purpose – domestic, commercial, educational, public administration.
