Preguntas frecuentes
›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.
