How are JSON arrays represented in the XML?

Each array item repeats its parent element name, which is the standard lossless convention — so a "tags" array of ["a","b"] becomes a b . A single element wraps the whole document so the output is always well-formed.

How accurate is the conversion?

Strings are XML-escaped for the ampersand, less-than and greater-than characters, and property names that aren't valid XML element names are sanitised. The structure maps deterministically, but XML has no native equivalent for JSON null, which is emitted as an empty element.

Is my JSON uploaded anywhere?

No. The conversion runs entirely in your browser with JavaScript — your data is never sent to a server or stored.

JSON to XML Converter

Convert JSON to XML in your browser

Legacy APIs, SOAP payloads and many config formats still expect XML, but modern data is usually JSON. This converter turns any valid JSON object or array into well-formed XML with consistent two-space indentation, so the result is always valid and ready to use.

How it works

The converter walks the JSON and maps each construct to XML:

Objects become nested elements, one per key.
Arrays repeat their parent element once per item — the standard lossless convention — so "tags": ["a","b"] becomes <tags>a</tags><tags>b</tags>.
A single <root> element wraps the whole document so it is always well-formed.
Escaping: the &, < and > characters in text are escaped, and property names that aren’t legal XML element names are sanitised.
Null has no XML equivalent, so it is emitted as an empty element.

Example

This JSON:

{ "name": "demo", "tags": ["a", "b"] }

becomes:

<root>
  <name>demo</name>
  <tags>a</tags>
  <tags>b</tags>
</root>

The tags array repeated the <tags> element once per item, and <root> wraps the document. The conversion happens entirely in your browser — your data is never uploaded or stored.
