JSON to XML Converter

How to Use the JSON to XML Converter

1. Paste your JSON into the input area.
2. Click Convert to XML.
3. Copy the XML output with the Copy button.

What It Does

The JSON to XML Converter transforms any valid JSON object or array into well-formed XML, entirely in the browser. It pretty-prints with two-space indentation, wraps array elements in <item> tags, sanitizes key names to valid XML element names, escapes all five OWASP XML special characters (&, <, >, ", '), and handles null values as self-closing elements. Output larger than 100,000 characters is shown truncated in the preview but the full XML is available via the Copy button.

Typical Uses

• Feeding XML-only systems. SOAP services, RSS pipelines, JAXB-based Java backends, and many enterprise integration buses still require XML payloads even when your source data is JSON.
• Generating test fixtures. Turn a JSON API response into an XML document to test an XSLT stylesheet, XPath query, or schema validator against realistic data.
• Sitemaps and feeds. Prototype the XML shape of a feed from structured JSON before writing the real serializer.

Mapping Caveats

JSON and XML do not map one-to-one, so any converter has to make choices worth knowing about. JSON has no attributes - every value becomes element text, never an attribute. Type information disappears: 42, "42", and true all serialize to plain text, so a round trip through XML loses the distinction. Key order is preserved as element order, but duplicate keys (illegal in JSON anyway) cannot be represented. And because XML element names are stricter than JSON keys, sanitized names like _1st_place will not round-trip back to the original 1st place key. If you need a lossless round trip, keep the JSON as the source of truth and treat the XML as a derived view.
