How markdown table generator works

Markdown tables are a compact way to show tabular data in README files, issues, and docs. Writing them by hand is fiddly because every row needs pipes and a separator row with dashes, so this generator builds them from plain data.

Paste your rows, choose the delimiter (comma, tab, pipe, or whitespace), and say whether the first row is a header. The tool splits each row, pads short rows so columns line up, and escapes any literal pipe characters in your data so they do not break the table.

The output is a standard GitHub-flavored markdown table: a header row, a separator row of dashes, then one row per data line. Click Copy to paste it straight into a README, issue, or markdown document.

Frequently asked questions

How do I make a markdown table?
Use pipes to separate columns, with a header row and a separator row of dashes. This generator builds that for you from CSV or other delimited data โ€” paste your rows and click Generate.
What delimiters are supported?
Comma (CSV), tab, pipe (|), and whitespace. Choose the one matching your data; the tool splits each row accordingly.
What happens to pipes inside my data?
They are escaped with a backslash (| becomes \|) so they do not break the table structure. This keeps GitHub-flavored markdown valid.
Does the first row have to be a header?
No. Set "First row is a header" to No and the tool inserts generic "Column 1, Column 2..." headers so the markdown table stays valid, treating all your rows as data.
