Office suite

FreeOffice is a complete office suite that includes a word processor, spreadsheet application, and presentation program, all of which offer seamless compatibility with their Microsoft Office counterparts (Word, Excel, and PowerPoint).

LibreOffice is an open-source office suite that is free to use — including for business purposes — and is available on Windows, macOS, and Linux systems alike. It consists of six applications: Writer (word processor), Calc (spreadsheet), Impress (presentation editor), Draw (drawing tool), Math (formula editor), and Base (database manager). Support and documentation for LibreOffice are provided by a dedicated community of users and developers. Anyone is welcome to join this community.
