    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.

    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. Invalid JSON is rejected with a clear error.

    FAQ

    Is my file uploaded?

    No. The conversion runs entirely locally in the browser - nothing is sent.

    How are XML attributes produced?

    Keys prefixed "@_" become attributes - exactly mirroring XML to JSON.

    Why a <root> element?

    XML needs exactly one root. Arrays and objects with several top-level keys are therefore wrapped in <root>.

    What happens to JSON arrays?

    Array entries become repeated <item> elements.

    Is a round-trip possible?

    Yes, the "@_" attribute convention matches our XML to JSON tool.
