FAQ

How do I make a Markdown table without counting pipes, for free?

Type your data into the grid and this page writes the pipes, the separator row and the column padding for you, producing neatly aligned Markdown — on your device with no upload.

Can I convert a CSV into a Markdown table?

Yes. Paste the CSV and it loads into the grid; the output pane shows the equivalent aligned Markdown table, which you can copy straight into a README or issue.

Is my content uploaded anywhere?

No. Editing and formatting happen entirely in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.

Does it produce GitHub-flavoured Markdown?

Yes — the output uses the standard header row, a | --- | separator and padded cells, which render correctly on GitHub, GitLab and most Markdown viewers.

Limits

Outputs a standard left-aligned table; per-column alignment markers (:---:) are not generated.
