Convert JSON to XML
JSON and XML both represent structured, nested data, but XML requires a single root element wrapping everything else — a concept JSON has no equivalent for. This tool maps every JSON object key to a same-named XML element, turns array items into repeated sibling elements under their field's tag, and lets you choose the root element name yourself.
Special characters (&, <, >, ", ') are escaped automatically, and any JSON key that wouldn't be a valid XML tag name — starting with a digit, containing a space, etc. — is sanitized so the output is always well-formed XML, not just XML-shaped text.
Runs entirely in your browser; paste JSON or drag and drop a .json file.
Why Convert JSON to XML?
Legacy System Integration
Older enterprise systems, SOAP-based services, and some banking or government APIs still only accept XML, even when everything upstream is JSON-native.
Config and Feed Formats
Some CI tools, RSS/Atom feeds, and configuration formats (like Maven POMs or Android manifests) are XML by convention, so converting a JSON payload into that shape saves hand-writing it.
Interop Testing
When integrating with an XML-based partner API, converting a sample JSON payload to XML is a quick way to sanity-check the shape you’ll need to send.
Example
The array under items becomes two repeated <items> elements rather than a single element with indexed children.
{
"status": 200,
"data": {
"id": "ord_9F3K2",
"items": [
{ "sku": "A1", "qty": 2 },
{ "sku": "B7", "qty": 1 }
]
}
}<root>
<status>200</status>
<data>
<id>ord_9F3K2</id>
<items>
<sku>A1</sku>
<qty>2</qty>
</items>
<items>
<sku>B7</sku>
<qty>1</qty>
</items>
</data>
</root>Features
Nested Objects → Nested Elements
Every object key becomes a child XML element, at any depth of nesting.
Arrays → Repeated Elements
Each array item becomes its own sibling element under the field’s tag name.
Configurable Root Element
Name the single root tag XML requires — JSON has no equivalent concept, so you choose it.
Well-Formed by Construction
Special characters are escaped and invalid tag names are sanitized automatically, then verified.
Upload a File
Drag and drop or upload a .json file to convert it directly, no copy-pasting required.

FAQ
Is this JSON to XML converter free?
Yes, it is completely free to use with no limits, signup, or account required.
Is my JSON uploaded to a server?
No. All conversion happens entirely in your browser using JavaScript. Your JSON is never uploaded or sent to a server.
How are JSON arrays converted?
Each array item becomes its own sibling XML element under the field’s tag name, e.g. a JSON "items" array with two entries becomes two separate <items> elements, not one element with indexed children.
How are nested objects handled?
Every object key becomes a child XML element, at any depth of nesting, mirroring the JSON structure.
Why do I need to choose a root element name?
XML documents require exactly one root element wrapping everything else, a concept JSON has no equivalent for. Since JSON has no built-in name for this, you choose it — it defaults to "root".
Are special characters escaped?
Yes. &, <, >, ", and ' are escaped as XML entities wherever they appear in text content, so the output stays well-formed even when your data contains them.
What happens if a JSON key isn’t a valid XML tag name?
Keys that start with a digit, contain spaces, or use other characters XML tag names don’t allow are automatically sanitized (invalid characters become underscores) so the output is always well-formed XML.
Can I upload a file instead of pasting?
Yes. Drag and drop or use the upload button to load a .json file.
Can I download the converted XML?
Yes, use the Download button to save the result as a standalone .xml file.
