JSON to XML converts structured JSON data into readable XML, translating between two data formats built about a decade apart for very similar reasons — describing structured data in a way both humans and machines can read.
Why would you need to convert JSON into XML at all?
Some older systems, enterprise APIs and data-exchange formats were built specifically around XML and were never updated to accept JSON, so converting a JSON payload into XML is often the only way to connect a modern API to a legacy system, or to prepare a feed format that specifically requires XML's structure.
How does the structure actually translate between the two formats?
JSON's key-value pairs and arrays map onto XML's nested elements and attributes — a JSON object generally becomes a parent XML element containing child elements for each key, though the exact mapping conventions can vary slightly depending on the target system's expectations.
Is this private and free, and does it run in the browser?
Yes — paste your JSON, get XML back, entirely in your browser with nothing uploaded, no sign-up and no limit on how many times you use it.
Why do these two data formats even both exist?
XML came first and was built for a much broader mission: the W3C began developing it in 1996, led by Jon Bosak, Tim Bray and others aiming to trim SGML — the dense, decades-old markup language behind HTML — down to something more practical, and XML 1.0 became an official W3C standard on February 10, 1998. JSON arrived about six years later, born from a much narrower, practical need: while building an online trading-card game called Cartoon Orbit at a company called State Software in the early 2000s, Douglas Crockford noticed that JavaScript already had a genuinely convenient built-in way to represent structured data, and rather than invent something new, he simply documented that existing subset of JavaScript syntax, publishing the first formal JSON specification in July 2006. JSON's appeal was exactly that it wasn't trying to do everything XML could — no schemas, no namespaces, no attributes-versus-elements debates — just a lightweight, readable way to move data around, which is why it eventually overtook XML for most web APIs even though XML got nearly a decade's head start.
Is JSON to XML free to use?
Yes. JSON to XML is completely free, with no sign-up and no usage limits.
Do I need to install any software?
No. JSON to XML runs directly in your web browser — nothing to download or install.
Is my data kept private?
Everything happens on your device. We never receive or store the file or text you enter into JSON to XML.
