What is it?

anydoc is a Rust library that converts Word (.doc, .docx), PowerPoint, Excel, OpenDocument, RTF, EPUB, CSV and PDF files into GitHub-flavored Markdown. Every format is parsed into a shared document model and rendered by one Markdown serializer, so escaping, tables, headings and footnotes come out the same regardless of the input format.

Output preserves headings, inline formatting, nested lists, tables with merged cells, footnotes, speaker notes and equations, which are rendered as LaTeX. Formats are detected from the file contents rather than the extension. Text-based PDFs are converted locally, while scanned pages can be sent to hosted OCR through Firecrawl Parse.

Bindings are available for Node.js, Python, the browser via WebAssembly, and a command-line tool that can be run with npx. The project is MIT licensed.
