AI Agent Markdown Converter

Problem It Solves

AI agents often need to read PDF, DOCX, XLSX, PPTX, images, audio, and HTML sources. Copying raw text can lead to Chinese PDF mojibake, lost structure, and inconsistent dependencies. markdown_everything converts these inputs into Markdown and handles Conda versus pip environment differences, reducing the complexity of external conversion pipelines.

How It Works

Key capabilities include:
- Environment management: commands such as check, list, exists, create, remove, install, setup, and run, preferring Conda and falling back to pip when unavailable.
- Document conversion: the convert command detects file types, calls MarkItDown, and writes Markdown to a file or standard output.
- Chinese PDF encoding repair: uses character-level Unicode extraction from pdfplumber to reduce mojibake and question marks; after conversion it checks Chinese character ratio, replacement characters, and anomalies, then falls back to standard conversion if needed.
- Cross-platform support: PowerShell and Bash scripts handle path differences on Windows, Linux, and macOS, and search common Conda install locations automatically.

Boundaries

It is useful for preparing office documents, web pages, structured data, and media for LLM processing. Conversion quality still depends on source clarity, OCR, speech recognition, and embedded fonts. It requires markitdown[all] and needs a prepared Conda or pip cache in offline environments.
