CSV 转 JSON 转换器

常见问题

›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.
