docling

Why we included this project

Docling is a document parsing library that handles the files people actually have: PDFs, DOCX, PPTX, XLSX, HTML, EPUB, and even audio and video. It converts them into a single structured document model that exports to Markdown, HTML, or lossless JSON. Reading order, table structure, layout, and formulas survive the conversion, so you feed a vector store or an agent real structure instead of a flat text dump. It runs locally for sensitive or air-gapped data, includes OCR for scanned pages, and has ready-made integrations with LangChain, LlamaIndex, and Haystack, which keeps the glue code minimal. For teams building knowledge bases, document Q&A, or agent workflows over real-world files, that structured output is usually the difference between a working pipeline and one that needs constant cleanup.
