Frequently Asked Questions

What Markdown format is used?

Standard GitHub-style tables: header row, then a separator row (dashes, with optional colons for alignment), then data rows. Pipes and backslashes in cell content are escaped so the table renders correctly.

What delimiters are supported?

You can use Auto to detect from the first line, or choose comma, semicolon, tab, or pipe.

What does column alignment do?

Alignment sets the separator row: left (default), center (:---:), or right (---:). Many Markdown renderers (e.g. GitHub) use this to align column content.

Can I use the first row as data instead of header?

Yes. Uncheck First row as header to use all CSV rows as data; the tool will generate a header row (Col 1, Col 2, …).

Can I choose the download filename?

Yes. Use the Download as field to set the filename (e.g. table). The tool adds .md if you do not include it.

Is my data secure?

Yes. Conversion runs entirely in your browser. Your data never leaves your device.
