About this skill

Problem Solved

Office documents, web pages, and media files are often stored as binary or proprietary formats. Feeding them directly to an LLM can lose structure, create encoding issues, and make batch processing harder. markitdown normalizes these inputs into Markdown while preserving headings, lists, tables, and links, making context easier to parse.

How It Works

It accepts files or stdin via CLI and chooses a conversion path based on extension, MIME type, and encoding hints. Use -o for output, -x pdf for stdin, and --keep-data-uris to retain base64 images. Common formats such as PDF, DOCX, PPTX, XLSX, HTML, EPUB, and CSV are handled directly; ZIP archives are traversed and converted file by file; audio and YouTube need transcription support.

Boundaries

Text extraction is the priority. It does not guarantee faithful reconstruction of PDF images, complex layouts, or scanned content. Audio conversion depends on ffmpeg and transcription components. For richer visual content, combine OCR with a second LLM pass. For batch jobs, verify the required extras are installed to avoid silent format failures.

Use Cases

  • Convert a PDF manual to Markdown, extracting headings, lists, and tables for LLM QA.
  • Batch convert Excel and HTML files inside a ZIP archive for unified field retrieval.
  • Extract structured content from DOCX/PPTX files to build model-readable prompt material.
  • Read image EXIF metadata and keep base64 data for downstream visual analysis.

Best For

  • RAG system engineers: convert PDF, DOCX, and PPTX into Markdown for model context.
  • Data engineers: batch parse Excel and CSV files in ZIP archives to extract table fields.
  • Content engineers: convert EPUB and HTML documents into structured text for summaries.
  • Evaluation engineers: extract PPTX and Word body text into Markdown for output comparison.
