What the JSON includes

`content.json` includes slide titles, paragraphs, bullets, tables, chart series, image metadata, speaker notes, shape text blocks, SmartArt text, raw text, and conversion warnings.

When to use JSON

JSON is best for agents, RAG ingestion, validation scripts, and automation that needs stable fields instead of prose. Use Markdown for direct LLM reading and HTML for human review.
