Is my data uploaded to a server?

No. Every operation runs inside your browser using JavaScript. Nothing you paste or open is sent to our servers, stored or logged. You can disconnect from the network after the page loads and the tool keeps working.

What happens to property names that are not valid XML element names?

They are adjusted to the nearest legal name: characters XML does not allow become underscores, and a name starting with a digit is prefixed with one.

JSON to XML

This tool runs entirely inside your browser, so it needs JavaScript enabled. Nothing you paste is ever sent to a server.
