JSON to XML

JSON is the language of modern APIs and web apps, yet many enterprise systems, SOAP services, RSS/Atom feeds, Office and configuration formats still require XML. This tool serialises your JSON tree into equivalent, well-formed XML.

The conversion runs entirely locally in your browser (fast-xml-parser, pure JavaScript). Object keys become elements; keys prefixed "@_" become XML attributes - exactly mirroring XML-to-JSON, so a round-trip is preserved. Because XML needs exactly one root element, a top-level array or an object with several top-level keys is wrapped in a <root> element; array entries become repeated <item> elements.

You will meet this when exporting to a legacy system, an XML-only import, a SOAP endpoint or an Office template. The result is indented, well-formed XML with an XML declaration - ready to open or feed into an XML toolchain. Invalid JSON is rejected with a clear error, and nothing is uploaded.

One structural difference shapes the result: XML requires exactly one root element. A JSON array at the root therefore gains an enclosing node, and array items of the same name become repeated elements of that name - precisely the shape XML processors and XSD schemas expect.

Specifications

In 3 steps

1. Drop or pick your JSON file.
2. The tool serialises it to XML.
3. Download the XML file.

Limitations: The result is well-formed XML with exactly one root element: arrays or objects with several top-level keys are wrapped in <root>, array entries become <item>. Keys prefixed "@_" become attributes - JSON has no native attribute concept, so without that prefix everything becomes elements. JSON numbers and booleans are written into the XML as plain text, since XML itself has no data types. Invalid JSON is rejected with a clear error.
