What It Does

Markdown tables are tedious to write by hand and easy to break - a missing pipe, a misaligned separator row, and the whole thing renders as plain text. This tool lets you edit the table as a grid, the way you would in a spreadsheet, and produces correct GitHub-Flavored Markdown automatically.

Add and remove rows and columns with one click
Set each column’s alignment (left / center / right) - the markdown separator row gets the right :---: colons
Watch the output update live as you type
Copy the result as Markdown, CSV, or HTML

Import What You Already Have

Paste an existing CSV or a markdown/pipe table into the import box and it loads straight into the grid, so you can keep editing a table you already started instead of rebuilding it.

Correct and Safe Output

Cell content that contains a pipe (|) is escaped as \| so it can’t break the markdown table structure, and the HTML output HTML-escapes every value. Nothing you type is rendered as live HTML - it is only ever emitted as text - so pasted content can’t corrupt the output or the page.

Handy alongside the Rich Text to Markdown converter and the Markdown Visualizer for previewing the result.

Limitations

Markdown tables themselves don’t support multi-line cells, merged cells, or nested blocks - that’s a limitation of the format, not the tool. Newlines in a cell are collapsed to spaces.
The grid is capped at 100 rows and 26 columns, which is far beyond what a readable markdown table should ever be.
