CSV/TSV to Markdown Table — GFM Pipe Tables
Convert spreadsheet CSV or TSV exports to GitHub-flavored Markdown pipe tables. Reverse mode copies a GFM table back to CSV/TSV. Paste or upload only — not a visual spreadsheet editor.
Developer notes
• GFM pipe tables only — no grid tables or merged cells. • Newlines inside cells become literal `<br>` when exporting to Markdown; the reverse conversion does not turn `<br>` back into newlines. • Auto-numeric alignment uses a period-decimal regex only — comma decimals (e.g. 3,14) stay left-aligned. • Cosmetic column padding in Markdown output does not change rendered semantics.
Options
Use cases
• Paste a spreadsheet CSV export into a README table. • Copy a GitHub table back to CSV for Excel or Sheets. • Pair with the Markdown TOC generator on the same hub. • Not for building tables cell-by-cell — use a spreadsheet export instead.

CSV/TSV to Markdown table FAQ
Browser-local
Is my data uploaded?
No. Conversion runs entirely in your browser. Optional file pick/drop reads the file locally — nothing is sent to FastMinify.
What is the size limit?
64 KiB (UTF-8) per paste or uploaded file, matching the other Text & Markdown tools.
Does round-tripping preserve newlines inside cells?
Not fully. CSV→Markdown replaces embedded newlines with `<br>`. Markdown→CSV leaves `<br>` as literal text — it is not converted back to a newline.
How does auto-numeric alignment work?
In auto mode, a column is right-aligned when more than half of its non-empty data cells match a simple period-decimal number pattern (e.g. 42 or 3.14). Comma-decimal values such as 3,14 are not treated as numeric.
