LibreOffice

LibreOffice is a free and open-source office productivity software suite developed by The Document Foundation (TDF). It was created in 2010 as a fork of OpenOffice.org, itself a successor to the discontinued StarOffice suite. The suite includes applications for word processing (Writer), spreadsheets (Calc), presentations (Impress), vector graphics (Draw), database management (Base), and formula editing (Math). It supports the OpenDocument format and is compatible with other major formats, including those used by Microsoft Office.
