Convert JSON, YAML, XML, CSV and 20+ formats in your browser

Paste text in any supported format and get it back in another. ParseBox detects the input format, peels Base64 and URL encoding, repairs broken JSON and tells you what the target format cannot keep. It also generates types for TypeScript, Zod, Go, Rust, Python and more from a sample.

ParseBox runs entirely in your browser. Your text is never uploaded, logged or stored on a server, so it is safe to paste API responses, tokens and config files.
