How do I convert JSON to XML?

Paste your JSON data into the input box or click "Upload JSON" to pick a .json file. The tool automatically formats it into clean, valid XML markup with proper tag nesting.

How do I specify XML attributes in JSON?

Prefix any key with "@_" to render it as an attribute on the enclosing element. For example, {"@_id": "101", "name": "Alice"} becomes Alice .

Can I customize the root element name?

Yes. Enter any custom tag name in the "Root Tag" field (default is "root"). If your JSON already contains a single top-level object, that tag will be used automatically.

Can I include or exclude the XML declaration header?

Yes. Use the checkbox to toggle the declaration header.

Is my data secure and private?

Yes. All parsing, transformation, and formatting run 100% inside your browser window. No data is ever sent to a remote server.
