Markdown Converter

Convert files to beautifully formatted Markdown in two steps: convert with uvx markitdown[all], then beautify with configurable style formatting.

Usage

/1coos-markdown-converter \x3Cfile-path> [--style github|commonmark|clean|obsidian] [--output-dir path] [--convert-only]

Parameters

Supported Formats

• Documents: PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx, .xls)
• Web/Data: HTML, CSV, JSON, XML
• Media: Images (EXIF + OCR), Audio (EXIF + transcription)
• Other: ZIP (iterates contents), YouTube URLs, EPub

Formatting Styles

github (default)

GitHub Flavored Markdown — table column alignment, fenced code blocks, task lists.

commonmark

Strict CommonMark — enforces sequential heading levels (no skipping h1 to h3).

clean

Minimal style — removes excessive formatting, simplifies redundant links.

obsidian

Obsidian Flavored Markdown — converts internal links to [[wikilinks]], normalizes callout syntax (> [!type]), formats properties/frontmatter, normalizes ==highlight== syntax, and aligns tables. Ideal for notes destined for Obsidian vaults.

Configuration

Core parameters are configurable via config.json in the skill directory:

{
  "style": "github",
  "outputDir": null,
  "convertOnly": false,
  "formatting": {
    "maxWidth": 80,
    "listMarker": "-",
    "emphasisMarker": "*",
    "strongMarker": "**",
    "codeBlockStyle": "fenced"
  },
  "converter": {
    "timeout": 60000,
    "charset": "UTF-8"
  }
}

CLI arguments always override config.json values.

Execution Instructions

When the user invokes this skill:

1. Check prerequisites: Verify uvx is available. If not, instruct the user to install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
2. Run conversion: Execute the script:

   bun run ${CLAUDE_SKILL_DIR}/scripts/main.ts $ARGUMENTS
   

3. Report results: Show the output file path and a brief summary of the conversion.
4. Handle errors:
   • Exit code 2: argument error — show the specific error message
   • Exit code 3: missing dependency — guide user to install uv
   • Exit code 4: conversion failure — suggest checking file format support

Examples

# Convert a PDF with default github style
/1coos-markdown-converter report.pdf

# Convert Word document with clean style
/1coos-markdown-converter document.docx --style clean

# Convert Excel to markdown without formatting
/1coos-markdown-converter data.xlsx --convert-only

# Specify output directory
/1coos-markdown-converter slides.pptx --output-dir ~/notes

Notes

• First run caches markitdown[all] dependencies; subsequent runs are faster
• Uses markitdown[all] to ensure full format support (PDF, OCR, audio transcription)
• Output preserves document structure: headings, tables, lists, links
• For complex PDFs with poor extraction, consider using Azure Document Intelligence
