Privacy details

Markdown table formatter processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using Markdown table formatter

Markdown table formatter uses the first row as the header, checks the column count and escapes vertical bars that would otherwise split a cell.

A worked example

Two tab-separated columns headed Item and Quantity become a Markdown header row, separator row and the original data rows.

Before you use the result

This accepts pasted spreadsheet-style TSV, not quoted CSV. Embedded line breaks in cells are not supported. Markdown table rendering depends on the destination app.
