Convert JSON to XML and XML back to JSON — attributes preserved, both directions.
Convert between JSON and XML in both directions. XML attributes map to @_-prefixed JSON keys and back, so structure round-trips. Malformed XML shows a clear error. Great for SOAP, RSS, and legacy APIs. Runs entirely in your browser.

JSON has no concept of attributes, so they are conventionally prefixed — often with @ — to distinguish them from child elements, with text content stored under a key such as #text. This is why XML to JSON is never quite clean: two distinct XML concepts have to share one JSON structure.
XML carries information JSON cannot express: namespaces, processing instructions, comments, CDATA sections and the distinction between an empty element and an empty string. It also preserves element order, whereas JSON object keys are unordered. Converting away and back therefore normalises some of that away.
Plenty of established systems: SOAP web services, RSS and Atom feeds, SVG, Office document formats, and many enterprise, banking and government integrations. XML also has schema validation and XPath querying, which are more mature than the JSON equivalents where strict contracts matter.
Yes, JSON to XML Converter is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
JSON to XML Converter runs entirely in your browser. Your file is never uploaded — it is read, processed and saved locally, so it never reaches our servers or anyone else's. You can disconnect from the internet after the page loads and it still works.
What it does: Converts between JSON and XML in both directions. Useful for working with SOAP/legacy APIs, RSS, config files, and data pipelines that mix the two formats.
Attributes: XML attributes become JSON keys prefixed with @_ (e.g. id="5" → "@_id": "5"), and convert back the same way, so structure is preserved. Malformed XML shows a clear error with the line.
Privacy: Everything runs in your browser. Nothing is uploaded.
