How do I convert a PowerPoint deck to Markdown?

POST the .pptx file to /v1/convert. Each slide becomes a Markdown section, which is what makes decks usable as RAG source material.

Are speaker notes included?

The conversion extracts the deck's text content. If you need to know precisely what came from where, use the async lane's JSON output rather than the flattened Markdown.

Why convert slides to Markdown at all?

Because a deck is unusable as LLM context in its native form. Flattening it to headed Markdown sections gives you the same chunk-by-heading pipeline you use for every other document type.

Slide decks are a common blind spot in document pipelines: the content is real, but nothing downstream can read it. POST /v1/convert accepts .pptx and returns the deck's text as Markdown, slide by slide.

curl

curl -F "file=@deck.pptx;type=application/vnd.openxmlformats-officedocument.presentationml.presentation" \
  https://api.mdkit.online/v1/convert

The markdown field of the JSON response holds the extracted text; meta carries the source filename.
