Convert Excel to Markdown.
Drop a workbook and turn each sheet into a clean Markdown table. It runs entirely in your browser, so your file never leaves your device.

Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Built to calculate,
not to embed.
A workbook lives inside Excel, awkward to paste into a doc, an issue or a prompt. Converting lifts each sheet out as a plain Markdown table you can drop anywhere, with the first row as the header.
| Region | Q1 | Q2 |
| --- | --- | --- |
| North | 120 | 140 |
| South | 90 | 110 |
Everything you
actually need.
Workbooks in, clean Markdown tables out, with no server and no account anywhere.
It never leaves your browser
Your workbook is read and converted on your own device. Nothing is uploaded to any server, ever.

AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
Every sheet
Each worksheet in the workbook becomes its own table, under a heading with the sheet name.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one workbook or a thousand; it all runs the same way, on your own device.
What survives
the trip.
Clear about what lands in the table and what stays behind. It mirrors the notes the Formats list keeps for Excel, so nothing here drifts from the real converter.

- Every sheet
