How JSON maps to XML

JSON has no notion of tags or attributes, so converting it to XML requires a set of mapping rules. This tool produces clean, well-formed XML with an XML declaration, proper escaping of &, <, >, and quoted attribute values.

Supported JSON features:

  • Objects — become XML elements with child elements
  • Arrays — become repeated elements with the same tag name
  • Strings — escaped text content
  • Numbers and booleans — serialized as text content
  • Null — empty elements (self-closing when the option is enabled)
  • Nested objects — nested elements to any depth
  • @key properties — converted back to XML attributes

If your JSON object has exactly one top-level key, that key becomes the root element; otherwise the document is wrapped in your chosen root element (default root). Top-level arrays place each item in an <item> element inside the root.

Examples

Simple object

{"name": "John", "age": 30} wrapped in a root element becomes <root><name>John</name><age>30</age></root>.

Single top-level key

{"person": {"name": "John"}} uses the key itself as the root: <person><name>John</name></person> — no extra wrapper.

Arrays as repeated elements

{"tags": ["a", "b"]} becomes <tags>a</tags><tags>b</tags> — the standard XML way of representing lists.

Round-trip with attributes

Keys starting with @ become attributes: {"user": {"@id": "42"}} produces <user id="42"></user>, which round-trips cleanly with the XML to JSON converter.

Frequently Asked Questions

What is JSON to XML conversion?+
It is the process of translating JSON values into an equivalent XML document: object keys become element tags, values become text content or child elements, and arrays become repeated elements.
How do I convert JSON to XML?+
Paste your JSON into the input panel, click Convert JSON to XML, then copy or download the result. You can set a custom root element and toggle self-closing empty tags.
Is this JSON to XML converter free?+
Yes — completely free, with no registration, no usage limits, and no watermarks.
Is my JSON uploaded to a server?+
No. Conversion runs entirely in your browser using built-in JavaScript APIs. Nothing is logged or stored.
How are JSON arrays represented in XML?+
XML has no native array type, so array items become repeated sibling elements sharing the parent key as their tag name. Top-level arrays use <item> elements inside the root.
What happens to null values?+
Null becomes an empty element. Enable "Self-closing empty tags" to output <tag /> instead of <tag></tag>.
Is the output guaranteed to be well-formed XML?+
Yes — the XML is produced by serializing structured values with proper escaping, never by string concatenation of raw input. You can double-check it with the XML Validator or pretty-print it with the XML Formatter.
