Convert CSV to Markdown.
Drop a .csv and get a clean Markdown table, every row and cell intact. 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.
Raw rows,
readable table.
A .csv is easy for machines but a wall of commas to read. Converting turns those rows into a proper Markdown table that renders anywhere, with the first line as the column header.
name,city,age
Ada,London,36
Bo,Paris,29
| name | city | age |
| --- | --- | --- |
| Ada | London | 36 |
| Bo | Paris | 29 |
Everything you
actually need.
Comma-separated rows in, a clean Markdown table out, with no server and no account anywhere.
It never leaves your browser
Your .csv is parsed right on your own device. Nothing is uploaded to any server, ever, however sensitive the data.
# Heading
- point one
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.
Any delimiter
The separator is detected automatically, whether the file uses commas, semicolons, tabs or pipes.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no row limits. Convert a tiny lookup table or a million-row export; it all runs the same way, on your own device.
Nothing gets
lost.
CSV is the one lossless case here: a file is already nothing but rows and cells, so it maps to a table one for one. The things other spreadsheets carry are simply not in a CSV to begin with.
Kept
4- Every row
- Every cell
- Header row
- Unicode / UTF-8
Not in a CSV
4- Cell formatting
- Formulas
- Multiple sheets
- Charts & images
Header, rows and empty cells all carry over. There is nothing to drop.
CSV questions,
answered.
Everything worth knowing before you convert a data file.

Have tables in other formats too? These convert the same way: privately, in your browser.
