## What it is
LibreOffice is a free, open-source office suite comprising Writer (word processing), Calc (spreadsheets), Impress (presentations), Draw (vector graphics), Base (databases), and Math (formula editor), compatible with most document formats including Microsoft Office and ODF. This repository contains the core C++ codebase maintained by The Document Foundation, with contributions handled via Gerrit.

## Use cases
- write documents and letters without paying for Microsoft Office
- open and edit Word, Excel, and PowerPoint files on Linux
- convert documents to PDF from the command line
- build a headless document conversion service
- embed office document viewing in my own app via LibreOfficeKit
- automate spreadsheet and document processing with UNO scripting

## When to choose
- you need a full-featured, free office suite across Windows, macOS, and Linux
- you want open-standards ODF support and broad Microsoft format compatibility
- you need headless document conversion or automation via UNO APIs
- you want software with no forced AI features or license fees, even commercially

## When to avoid
- you need real-time collaborative editing on par with Google Docs out of the box
- you require pixel-perfect fidelity for complex Microsoft Office documents
- you want a lightweight editor rather than a full suite
- you plan to contribute via GitHub pull requests - the project uses Gerrit instead
