What is docling?

Docling is an open-source Python library that converts PDFs, DOCX, PPTX, XLSX, HTML, and image files into machine‑readable formats like Markdown and JSON. It preserves layout details such as reading order, tables, and figures, making the output ready for downstream generative‑AI and retrieval‑augmented generation workflows. Available as both a Python package and a command‑line interface, Docling runs on Windows, macOS, and Linux and can be deployed in cloud or SaaS environments. It integrates smoothly with version‑control platforms like GitHub and GitLab, and support is provided via documentation and email.
