Document Converter

Overview

Use this skill when you need to convert common document and data formats while preserving as much structure as the source format allows. The bundled CLI covers lightweight, local conversions between Markdown, HTML, CSV, JSON, YAML, TOML, plain text, Excel, and PDF output.

The core conversions use the Python standard library: JSON, CSV, HTML parsing, Markdown heuristics, TOML reading via tomllib, and custom TOML/YAML writers. PDF output uses pandoc and Excel reading uses openpyxl — both are required dependencies for those conversion paths. If a dependency is missing, the tool exits with a clear installation hint instead of failing with a traceback.
