Can I convert CSV or TSV to a Markdown table?

Yes. Paste comma-separated or tab-separated rows and the formatter converts them into a Markdown table with a header and separator row.

Does the formatter preserve Markdown column alignment?

Yes. Preserve mode reads left, center and right alignment markers from an existing separator row. You can also apply one alignment to every column.

Is my table uploaded?

No. Parsing, formatting and copying happen locally in your browser.

Markdown table FAQ

Can I convert CSV or TSV to Markdown?

Yes. The formatter detects commas or tabs when the input is not already a pipe-delimited Markdown table.

What happens to alignment markers?

Preserve mode keeps valid left, center and right markers from an existing Markdown separator row. The alignment menu can also override every column.

How are pipe characters inside cells handled?

Literal pipe characters are escaped in the output so they do not create accidental columns.

Is pasted data sent to a server?

No. Formatting and copying run locally in your browser.

Working with JSON instead? Try JSON Stringify or inspect line-delimited data with the JSONL Viewer.
