Is this Markdown Table Merger free?

Yes. Free forever, no account required. Runs 100% in your browser.

How does the join work?

It's a SQL-style join on a shared key column. Inner returns only matched rows, left keeps every row from A, outer keeps every row from both sides.

Can the key columns be in different positions?

Yes. Use Key column A and Key column B to specify the 0-based index in each table.

What fills missing cells in left/outer joins?

By default, empty string. Use the Fill missing field to customize (e.g. N/A, 0, or -).

Is my Markdown uploaded?

No. Runs 100% in your browser. Your text never leaves your device.
