Convert Word (DOCX) to Markdown

Convert a Word document to Markdown via the mdkit REST API — headings, lists and tables come out as clean Markdown structure.

Word documents (.docx) convert synchronously on POST /v1/convert. Headings, lists and tables in the document come out as Markdown structure, which is exactly what an LLM or a RAG chunker wants.

curl

The DOCX MIME type is long — set it explicitly so the upload passes the content-type check:

curl -F "file=@spec.docx;type=application/vnd.openxmlformats-officedocument.wordprocessingml.document" \
  https://mdkit.online/v1/convert

Notes

Sync uploads are capped at 8 MB; bigger files go through async jobs (up to 50 MB).
Unsupported types are rejected with 415 — accepted types are PDF, DOCX, PPTX, XLSX, HTML and plain text.
Anonymous calls are rate-limited per IP; send an X-API-Key header to lift the limit.
