JSON to XML Converter

The mapping

This is the reverse of the XML to JSON converter: keys starting with @ become attributes, #text becomes the element text, and arrays repeat the element. An object with a single key uses it as the root element; anything else is wrapped in <root>.

Escaping and names

Ampersands, angle brackets and quotes are escaped, and keys that are not valid XML names have their invalid characters replaced with underscores.

Is my data safe?

Yes. Everything runs in your browser — nothing you paste is sent to a server, so payloads with customer data or credentials stay on your machine. Large inputs of several megabytes are processed once you stop typing, without freezing the page.
