Convert TSV to Markdown.
Turn tab-separated rows into a tidy Markdown table, with the first line read as the header. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files
or
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.
Tabs are great,
pipes are better.
A TSV holds its columns with invisible tab characters that only line up in a code editor. Converting redraws those same rows as a Markdown table anything can render.
sku qty stock
A100 4 120
A220 12 60
Columns split on tabs, not spaces.
| sku | qty | stock |
| --- | --- | --- |
| A100 | 4 | 120 |
| A220 | 12 | 60 |
Everything you
actually need.
Tab-separated rows in, a clean Markdown table out, with no server and no account anywhere.
It never leaves your browser
Your .tsv is parsed and converted on your own device. Nothing is uploaded to any server, ever.
# 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.
Tabs, not commas
Fields split on tabs, so a value that contains commas stays whole, with no escaping to untangle.
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 file or a thousand; it all runs the same way, on your own device.
Tabs in,
a real table.
TSV is a lossless, one-to-one mapping: every tab boundary becomes a column divider, so the data lands in Markdown exactly as it was, with nothing meaningful left behind.
Kept
4- Every row
- Every cell
- Header row
- Unicode / UTF-8
Not in a TSV
4- Styling
- Formulas
- Multiple sheets
- Charts & images
Header and every data row land in the table, so nothing on the page is left behind.

Everything worth knowing before you drop in a tab-separated file.
