JSON to XML Converter

Convert JSON to XML for free — paste JSON or open a file and get well-formed XML instantly. Arrays repeat the element, keys starting with @ become attributes, “#text” becomes element text, special characters are escaped and invalid element names are made safe. Choose the root and array item names, indentation, and whether to add the XML declaration.

Frequently asked questions

How do I make XML attributes from JSON?

Prefix the key with @ — {"book": {"@id": "bk101"}} becomes <book id="bk101"/>.

What happens to JSON arrays?

Each item becomes a repeated element with the array's key as its name. A top-level array is wrapped in the root element with “item” elements (you can rename both).

Does it escape special characters?

Yes — &, < and > are escaped in text, and quotes too in attributes, so the XML is always well-formed.

Is my data uploaded?

No. It's converted in your browser — nothing is sent to a server.
