This fast, lightweight word processor offers most of the functions the average person uses regularly. It isn't as pretty as some of the newer word processors, but it gets the job done. Operating System: Windows, Linux, OS X

2. Gnumeric

Gnumeric isn't meant to be an Excel clone, but it can read Excel files. It also offers some features Excel doesn't, like 154 exclusive functions, basic support for financial derivatives, basic support for telecommunication engineering, and more. Operating System: Windows, Linux.

3. KOffice

This suite includes word processing (KWord), spreadsheet (KSpread), presentation (KPresenter) and database (Kexi), vector drawing (Karbon), project planning (KPlato), diagramming (Kivio) and painting (Krita) tools. The tools are fairly robust, but the interfaces may take a little getting used to if you've only used Microsoft Office in the past. Operating System: Windows, Linux

4. LibreOffice

LibreOffice is an old standby——with a new name. Some of the leaders behind broke free from Oracle and created their own version of the well-known open source office productivity suite. It's still officially in beta, but it includes the capabilities of its predecessor, including compatibility with Microsoft Office. Operating System: Windows, Linux, OS X.
