Build a Markdown table

Writing pipe tables by hand is miserable. Edit the cells in a grid, set the column alignment, and copy Markdown that is padded so the source stays readable.

How it works

  1. Edit the cells, or paste CSV / TSV / an existing table and import it.
  2. Set the alignment per column.
  3. Copy the Markdown.

Why nothing is uploaded

Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.

Verify it yourself

  1. Open your browser’s developer tools (F12) and select the Network tab.
  2. Load your file and run the tool.
  3. The only requests you will see are the tool’s own code and, once cached, none at all.

Frequently asked questions

Does the padding handle Japanese?

Yes. Full-width characters occupy two columns in a monospaced editor, and the padding accounts for that, so a table with Japanese in it still lines up in the source.

Can I edit a table I already have?

Yes — paste it into the import box. The existing alignment row is read too, so you do not lose the column alignments.

Is anything uploaded?

No. The whole editor is client-side.
