anydoc is a Rust library that converts 14 document formats (Word, PowerPoint, Excel, PDFs, etc.) into clean GitHub-flavored Markdown in milliseconds. It works across Node.js, Python, and the browser via WebAssembly, and benchmarks show it's 200x faster than LibreOffice while scoring higher quality than competing tools. The library parses any format into a shared document model, so tables, headings, and formatting behave consistently regardless of input type.

• anydoc converts 14 document formats to Markdown in ~4.4ms per file versus LibreOffice's 1129ms—about 200x faster
• In benchmarks against 6 competitors on 100 documents, anydoc scored 81 overall (vs. 40-70 for others) and was the only tool supporting all 14 formats
• It works by parsing every format into a shared document model before rendering to Markdown, keeping tables, headings, and formatting consistent regardless of input type
• Scoring was done by Claude Sonnet as a blind judge against ground-truth images across 482 verdicts
