Convert Excel (XLSX) to Markdown tables

Convert Excel spreadsheets to Markdown tables with the mdkit API — a table an LLM can actually read, without cell-by-cell parsing code.

Spreadsheets convert to Markdown tables — a representation LLMs handle far better than raw XML or CSV blobs with lost headers. Upload the .xlsx to POST /v1/convert like any other document.

curl

curl -F "file=@figures.xlsx;type=application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" \
  https://mdkit.online/v1/convert

Notes

Each sheet's cells come out as Markdown table rows.
Very large workbooks can exceed the 8 MB sync cap — use the async lane (50 MB) for those.
