How are arrays represented in XML?

Each array item becomes a repeated element with the same tag name, the standard convention XML consumers expect.

What happens to keys that aren't valid XML names?

Invalid characters are replaced with underscores and names that start with a digit are prefixed, so the output is always well-formed.

Bridging JSON APIs and XML systems

Plenty of enterprise systems — SOAP services, RSS pipelines, legacy imports — still require XML. This converter maps objects to elements, repeats elements for arrays, escapes special characters, and sanitizes keys into valid tag names.

Everything runs in your browser — your JSON never leaves your device, so it is safe for API keys, customer records, and production payloads.
