Is my JSON data uploaded to a server?

No. The conversion runs entirely in your browser with JavaScript. Nothing is sent over the network, which makes the tool safe for sensitive data.

How is the root element chosen?

If your JSON object has a single root key, that key becomes the root element. Otherwise the output is wrapped in a element.

Can I produce XML attributes?

Yes. Keys prefixed with @_ become XML attributes, which makes round-tripping with the XML to JSON tool on this site faithful.

Why convert JSON to XML?

Many legacy systems, feeds and enterprise APIs still speak XML. Paste your JSON above and get cleanly indented XML in milliseconds, without installing anything.

How it works

The converter parses your JSON locally and serializes it as indented XML. The output is wrapped in a <root> element unless your object has a single root key, and keys prefixed with @_ become attributes — the same convention used by the XML to JSON tool on this site, so round trips are faithful.
