How are arrays represented in the XML output?

Each array item becomes a repeated element with the same tag name. For example, the JSON {"items": [1, 2]} becomes 1 2 inside the root element.

What happens to invalid XML element names?

JSON keys that start with a digit or contain spaces are not valid XML element names. The converter sanitizes them by prefixing with an underscore and replacing invalid characters.

Is anything sent to a server?

No. Conversion happens entirely in your browser.

Free Online JSON to XML Converter

Convert JSON objects into clean, well-formed XML with our online JSON to XML converter. Useful when integrating modern JSON APIs with legacy XML systems, generating SOAP request bodies, building RSS or sitemap feeds, or producing structured data for tools that only accept XML.

How the conversion works

Object keys become XML element names
Array items become repeated elements with the same tag
Primitive values (strings, numbers, booleans) become element text content
Null becomes a self-closing element
Invalid XML names are sanitized (e.g. a key starting with a digit is prefixed with an underscore)

Customisable output

Root element name: Default is root — change it to response, data, or anything you need
XML declaration: Toggle the <?xml version="1.0" encoding="UTF-8"?> prolog on or off
Indentation: 2 or 4 spaces for pretty output, or minify for compact transmission

Common use cases

Generate XML payloads for SOAP-based services
Translate REST responses into XML for legacy reporting tools
Build sitemap, RSS, or Atom feeds from JSON sources
Produce sample XML files from JSON test fixtures

Pair with related tools

After converting, run the result through the XML Formatter for additional polish or the XML Validator to confirm well-formedness. To convert back, use the XML to JSON converter.
