Convert ODS to Markdown.
Drop a LibreOffice Calc spreadsheet and get every sheet back as a plain Markdown table. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files

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.
An open sheet,
plain values.
An .ods file is the open spreadsheet standard, but its grids are awkward to paste into a doc or a prompt. Converting reads each sheet and lays the cell values out as a tidy Markdown table, formulas shown as their last saved result.
| Product | Units | Total |
| --- | --- | --- |
| Desk | 12 | 1440 |
| Chair | 30 | 1350 |
Everything you
actually need.
Calc spreadsheets in, clean Markdown tables out, with no server and no account anywhere.
It never leaves your browser
Your .ods file is unzipped and read on your own device. Nothing is uploaded to any server, ever.
# Heading

3 chunks
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
Every sheet in the .ods file is read in turn and written as its own table, titled 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 spreadsheet or a thousand; it all runs the same way, on your own device.
What survives
the trip.
Upfront about which parts of the sheet make it across. This matches the notes the Formats list keeps for OpenDocument Sheet, so the page stays honest about the converter.
Kept

- Every sheet
