Open Source Software Office Applications
This page will briefly describe some of the more important office software available as open source. Emphasis will be on the applications available through LibreOffice which is the most popular set of open source software which provides much of the functionality of the Microsoft Office products. A preliminary list of other applications is also provided. This list will be added to over time. A comparison of features in MS Office and LibreOffice is available at

The most recent version of LibreOffice is 6 but earlier versions  may be the standard download on some versions of Linux. LibreOffice Write, Calc and Impress are automatically loaded on the installation of most Linux versions. The other LibreOffice applications, Draw, Base Math, etc. software can be loaded application by application or as a complete package. All are available in a number of different language interfaces. LibreOffice applications can save data to a number of different formats including pdf. The software provides a full range of tools, however,power users of the equivalent MS Office tools will find gaps in tools provided. The latest version of LibreOffice for Linux, Windows or Apple is available at for the complete software or any components. Documentation and users' manuals can be downloaded from

LibreOffice Write: Resembles a slightly older version of MS Word. The user interface is straightforward. The data can be saved either in the LibreOffice format or one of the MS Office word processing formats.

LibreOffice Calc: This software also operates like a slightly older version of Excel. Data can be saved either in the LibreOffice format or one of the many Excel formats as well as generic format (like CSV--Comma Separated Values.)  This application also reads and writes dbf files (not supported in Windows) which is useful in dealing with "attribute" tables in GIS shapefiles. The creation of graphs is straightforward, but somewhat different from Excel and may require some getting used to.

LibreOffice Impress: This programme is the "PowerPoint" equivalent of the suite. It allows files to be saved in the LibreOffice format as well in various versions of PowerPoint.

LibreOffice Draw: A drawing programme for diagrams, flow charts, etc. The data can be saved in the LibreOffice format or "exported" into a number of graphics and other formats.

LibreOffice Formula: Software to prepare mathematical formulas.

LibreOffice Base:Is the database application in the suite. It is not included with the original installation. It is lacks many of the functions of Microsoft's Access software. Inexperienced database users will be able to use it to get some data base experience.

LibreOffice Charts: For building charts and graphs

LibreOffice Maths: This is an equations and formula editor.
