ASCII Table Generator
Convert CSV/TSV data into beautifully formatted ASCII or Markdown tables.
About this tool
Paste CSV or TSV data (or use the built-in visual row/column editor) and instantly generate a formatted table in one of five styles: Classic ASCII with + and - borders, Rounded box-drawing characters, Double-line Unicode borders, Minimal (header separator only), or GitHub-flavoured Markdown. Per-column alignment (left, centre, right) is configurable, and you can toggle whether the first row is treated as a header. One-click copy puts the result straight into your clipboard.
How to use
- 1 Paste your CSV or TSV data into the input area, or use the visual editor.
- 2 Choose a table style from the style selector.
- 3 Set per-column alignment as needed.
- 4 Toggle 'First row is header' if applicable.
- 5 Click Copy to copy the formatted table to your clipboard.
