Microsoft’s open-source Python utility: MarkItDown converts diverse file formats (Word, PDF, audio) into structured Markdown for seamless LLM ingestion.

MarkItDown operates as the universal translator for your data pipeline, converting complex formats like Word (.docx), Excel (.xlsx), and even audio files (via transcription) into clean, structured Markdown. Developed by Microsoft and available as a Python package, it prioritizes preserving document structure (headings, tables, links) over simple text extraction. This core capability is critical: it prepares diverse data for Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG) systems, significantly lowering the data preparation barrier for AI applications.

## Recent Public Talks and Demos

### [Simple Retrieval with Codex CLI and Bash](https://seattle.aitinkerers.org/talks/rsvp_9-gmI6Gpuh0)

Parallel document extraction demo using multiple Codex CLI instances running simultaneously. Each agent uses the experimental_instructions_file field to receive specialized prompts for extracting different information (payment amounts, deadlines, parties, etc.) from contracts; no embedding pass needed. Live bash script demo with timestamped results.
