How to use
- Paste your CSV (or TSV, or a semicolon-separated export from Excel) into the left box, or drop a file. The delimiter is detected automatically.
- Adjust options. Untick "First row is header" if your data has none, choose per-column alignment, and turn off pretty-align if you want a compact table.
- Copy or download the Markdown. The rendered preview shows exactly how GitHub, Obsidian or Notion will display it.
FAQ
Does it handle commas and quotes inside cells?
Yes. The parser follows RFC 4180: fields wrapped in double quotes may contain commas, newlines and doubled quotes (""). Newlines inside a cell are converted to <br> so the Markdown table stays on one line per row.
How is the delimiter detected?
The tool counts commas, semicolons, tabs and pipes on the first few lines outside quoted fields and picks the one that appears most consistently. You can override it in the Delimiter menu.
Why are numeric columns right-aligned?
Markdown tables support alignment with colons in the separator row (---:). Numbers are easier to compare when right-aligned, so columns where every non-empty cell is a number get that alignment automatically. Change any column's alignment with the small selectors under the options.
Can I convert a Markdown table back to CSV?
Yes — switch to the Markdown → CSV tab, paste the table (with or without leading and trailing pipes) and copy the CSV. Escaped pipes and simple inline formatting are cleaned up.
