Veelgestelde vragen

Does my header row need quotes?

Optional. We handle both quoted and unquoted headers, with comma or tab delimiters.

Are numbers auto-detected?

Yes. If a value parses as a number, it becomes a JSON number; otherwise it stays a string. Booleans (true/false) are also detected.

What delimiter is used?

Comma is default. Tab and semicolon are auto-detected from the first line.

Is my CSV uploaded?

No — conversion runs entirely in your browser.

Is the converter free?

Yes — fully free, no signup.
