anydoc

Overview

anydoc is an open-source Rust library by Firecrawl that converts Word, PowerPoint, Excel, OpenDocument, RTF, EPUB, CSV, and PDF documents into GitHub-Flavored Markdown. It provides Node.js, Python, browser WebAssembly, and CLI bindings, and its browser demo converts files locally.

Key Features

• Converts Word, PowerPoint, Excel, OpenDocument, RTF, EPUB, CSV, and PDF files into GitHub-Flavored Markdown.
• Uses one shared document model and Markdown serializer so output structure stays consistent across formats.
• Detects formats from file bytes rather than extensions, so mislabeled files still convert.
• Runs as pure Rust with no ML models or external services and reports median conversion under 5 ms.
• Ships bindings for Rust, Node.js, Python, browser WebAssembly, and CLI usage.
• Preserves headings, lists, tables with merged cells, footnotes, speaker notes, and equations as LaTeX.

Use Cases

• Converting mixed office document collections into one consistent, structured Markdown output for LLM pipelines.
• Converting documents locally in the browser so files never leave the user's machine.
• Letting agents read office documents through the shipped Agent Skill.
• Extracting text-based PDFs locally without requiring an OCR service.

Getting Started

• Install anydoc for Rust with cargo add anydoc, for Node.js with npm install @firecrawl/anydoc, for Python with pip install firecrawl-anydoc, or for the browser with npm install @firecrawl/anydoc-wasm.
• Run the CLI with npx @firecrawl/anydoc report.docx, or use the same conversion API from a path or bytes.
• Stop at the document model when embedded assets need to be kept.

Deployment & Requirements

• Pure Rust, no ML models, and no external services for local conversion.
• Browser WebAssembly demo downloads a few MB of WebAssembly once.
• Text-based PDFs convert locally through pdf-inspector; scanned or image-only PDFs require opt-in hosted OCR through Firecrawl Parse.
• Hosted OCR can be used without signup; setting FIRECRAWL_API_KEY provides higher limits.
• The Rust crate has no OCR option and never makes network calls.

Before You Adopt

• License: MIT. Review its terms before using, modifying, or distributing the project.
• Scanned or image-only PDFs are not handled by local conversion and rely on Firecrawl Parse for OCR.
• When hosted OCR is used, the entire document is sent off the machine because Parse has no page selection.
