Tables for GitHub and plain text
Use Markdown in a GitHub README. Use ASCII or Unicode inside a monospace code block or terminal. CSV supports quoted commas, doubled quotes and multiline cells. Spreadsheet input uses tabs, not spaces. Emoji and wide characters can depend on the display font.
Limits
Up to 20,000 input characters, 100 rows, 12 columns and 120 characters per cell. Bordered tables can be at most 240 character positions wide. Output is limited to 100,000 characters. Invalid or oversized input is rejected, never silently truncated.
Your data stays in this page
Table data is not uploaded or saved in browser storage. Optional analytics count tool actions without the cell contents. Copy or download your result before leaving.
