Free Markdown table generator
Paste comma- or tab-separated values (for example from Excel or Google Sheets). Pick whether the first row is a header, adjust delimiter detection if needed, then copy the Markdown. Rendering stays in this tab — nothing is uploaded.

Quick facts

| Excel paste? | Spreadsheet apps usually paste tabs between columns; Auto mode prefers tabs when they dominate the first line. |

FAQ
Which Markdown flavor is this?▾
Output uses pipe tables compatible with GitHub-flavored Markdown (GFM) and most modern Markdown renderers.
Why does Auto pick the wrong delimiter?▾
Heuristics look at the first non-empty line. If a row has many commas inside quoted fields, force Tab or Comma explicitly.
Can I use semicolon-separated CSV?▾
Not in this version — convert to comma or tab first, or replace semicolons in a text editor.
Do you support TSV files?▾
Yes. Paste TSV text or choose Tab as the delimiter.
What about pipes inside cells?▾
Pipe characters are escaped for Markdown so the table structure stays valid.
Will formulas copy from Excel?▾
Spreadsheets paste evaluated values, not formulas. Copy the computed text you see in cells.
