LibreOffice is the best free office suite around, and as such has been adopted by all major Linux distributions. Although LibreOffice is already packed with features, it can be extended by using specific add-ons, called extensions.

The main LibreOffice extensions website is extensions.libreoffice.org. Extensions are tools that can be added or removed independently from the main installation, and may add new functionality or make existing functionality easier to use.

1. MultiFormatSave

MultiFormatSave lets users save a document in the OpenDocument, Microsoft Office (old and new), and/or PDF formats simultaneously, according to user settings. This extension is extremely useful during the migration from Microsoft Office document formats to the Open Document Format standard, because it offers the option to save in both flavors: ODF for interoperability, and Microsoft Office for compatibility with all users sticking to legacy formats. This makes the migration process softer, and easier to administer.
