Comment ça marche

JSON and XML are the two most common data interchange formats, and you frequently need to move between them. This converts in both directions, in your browser.

1
You paste JSON or XML
Pick a direction with the ⇄ toggle. The input is parsed locally — JSON with JSON.parse, XML with the browser's DOMParser.
2
It maps the structures
Going to XML, object keys become elements, "@name" keys become attributes, and arrays repeat a tag. Going to JSON, attributes become "@name" keys, repeated tags become arrays, and numbers/booleans are coerced.
3
You get clean, indented output
The result is pretty-printed and ready to use.
4
Round-trip if you like
The ⇄ button feeds the output back as input so you can convert back and check.
