convert-documents-to-markdown

Convert Word, PowerPoint, Excel, OpenDocument, RTF, EPUB, CSV, and PDF to clean Markdown. Built in Rust, with Node.js and Python bindings.

Features

• ✓**One output for every format.** Each format parses into a shared document model and renders through a single Markdown serializer, so escaping, tables, heading anchors, and footnotes behave identically whether the input was a `.doc` from 2003 or a `.pptx` from yesterday.
• ✓**Full document structure.** Headings with anchors, bold/italic/strikethrough, inline code and code blocks, links and internal cross-references, bulleted/numbered/nested/task lists with the source's own numbering, tables with merged cells and header rows, block quotes, footnotes and endnotes, and speaker notes.
• ✓**Equations as LaTeX.** Word and PowerPoint (OMML), OpenDocument and EPUB (MathML), and RTF equations convert to GitHub-flavored math: `$...$` inline and `$$` blocks.
• ✓**Embedded assets.** Images and embedded objects render as their alt text in the Markdown, and the raw bytes stay available on the document model, tagged with their media type. Images with an external URL become ordinary Markdown images.
• ✓**Content-based format detection.** The format is read from the bytes themselves (PDF header, RTF open group, OLE stream names, ZIP package mimetype), so mislabeled files still convert correctly.
• ✓**Fast.** Pure Rust, no ML models, no external services. Median conversion time is under 5ms per document.
• ✓**Bindings that stay out of the way.** Node.js conversion runs on the libuv thread pool and never blocks the event loop; Python releases the GIL so other threads keep running. TypeScript types and Python stubs ship with the packages.
• ✓**PDF support built in.** Text-based PDFs convert locally through [pdf-inspector](https://github.com/firecrawl/pdf-inspector), no OCR service required. Scanned pages can opt into [hosted OCR](#scanned-pdfs-ocr).
• ✓**Agent ready.** Ships as an [Agent Skill](#agent-skill): one `npx skills add firecrawl/anydoc` and any agent can read office documents.
