LibreOffice Core. The source code for the free office suite.

In simple English

This is the source code for a complete office suite. It includes a word processor, spreadsheet, and presentation maker. You can use it as a free alternative to commercial office software. This repository is only for viewing the code or building the app. Most people should download the ready-to-use version from the official website instead.

What it is

This repository is the main code base for LibreOffice, written mostly in C++. It holds the logic for the word processor, spreadsheet, and other desktop tools.

What it is good for

C++ developers who want to fix bugs, add features, or compile their own custom version of the office suite.
