JSON to XML

Convert JSON objects to XML with a configurable root tag, array element names, attributes, and indentation.

For this tool, processing runs locally in your browser and data is not sent to the server.

JSON to XML is a free online converter that transforms valid JSON into XML for legacy integrations, APIs, SOAP-like payloads, data exchange formats, tests, and dev tasks. You can set the root tag, array element names, add an XML declaration, configure indentation, and use _attributes or @key for XML attributes. The tool runs in your browser and does not send data to the server.

More about this tool

JSON to XML converts valid JSON into XML for legacy integrations, APIs, SOAP-like payloads, data exchange formats, tests, and dev tasks. You can specify a root tag, an array element name, add an XML declaration, configure indentation, use _attributes or @key syntax for XML attributes, and use _text for a node's text content.

The tool validates JSON before conversion and warns about structures that may produce ambiguous XML. Special XML characters in text values and attributes are properly escaped.

All processing is done locally in the browser. Your data is not sent to the server.

Frequently Asked Questions

How do I convert JSON to XML?

Paste valid JSON, specify the root tag, and click Convert. The tool transforms objects, arrays, and values into an XML structure.

Why is a root tag required?

An XML document must have a single root element. JSON needs to be wrapped in a container tag such as root, request, or response.

How are JSON arrays converted?

Arrays are converted to repeating XML elements. The element name can be configured, for example item, row, product, or entry.

How do I add XML attributes through JSON?

Use an _attributes object or keys with an @ prefix. For example, _attributes: { id: "1" } produces the attribute id="1".

What does the _text field do?

_text is used as the text content of an XML element, particularly when the element has both attributes and text.

Are XML special characters escaped?

Yes. The characters &, <, >, and quotes in text values and attributes are properly escaped so the XML remains well-formed.

Can I include an XML declaration?

Yes. You can enable the line <?xml version="1.0" encoding="UTF-8"?> at the beginning of the output.

How is this different from XML to JSON?

JSON to XML creates XML from JSON. XML to JSON does the reverse: it parses XML and outputs JSON.

Does the tool validate XSD or SOAP schemas?

No. The tool only converts the data format. XSD schemas, SOAP contracts, and business rules must be validated with dedicated validators.

Is my data sent to the server?

No. JSON is processed locally in the browser and is not sent to the server.

Do I need to register?

No. The tool works immediately without registration.
