Many legacy systems, SOAP APIs, and enterprise integrations still expect XML rather than JSON, making conversion a routine task for integration developers. This JSON to XML converter takes any JSON object or array and generates a properly nested XML document, turning keys into tags and array items into repeated elements. It's useful for developers bridging modern JSON APIs with older XML-based services, or anyone preparing test data for an XML-consuming system. The converter preserves data types and structure faithfully so the resulting XML mirrors your original JSON hierarchy. Since everything runs client-side in your browser, your data is never uploaded, and there's no signup needed. Paste your JSON below to generate valid XML output instantly.

Frequently asked questions
How does JSON to XML conversion work?
Each JSON key becomes an XML tag name, string and number values become element text content, and array items are repeated as sibling elements under the same parent tag.
Can I set a custom root element for the XML output?
Yes, you can specify the root element name since JSON doesn't have a top-level tag equivalent.
Does this tool support JSON with attributes-style data?
Yes, keys prefixed for attributes are mapped to XML attributes on the corresponding element where supported.
Is my JSON data sent to a server during conversion?
No, the entire conversion runs locally in your browser using JavaScript, so your data stays private.
What happens to null values in the JSON?
Null values are typically rendered as empty or self-closing XML elements to preserve the original structure.
Can I convert the resulting XML back to JSON?
Yes, use the companion XML to JSON converter to reverse the transformation.
Is there a size limit for JSON to XML conversion?
There's no fixed limit - typical API responses and config files convert instantly since processing is local.
