Why use JSON to XML?

This tool parses the JSON you paste and walks it recursively, turning each key into an XML element. Nested objects become nested elements, and when a value is an array, every item in that array is repeated as its own sibling element using the same tag name as the array's key. Primitive values, strings, numbers, booleans, become the text content of a leaf element, and any reserved character inside a string, like an ampersand, angle bracket, or quote, is escaped to its XML entity so the output stays well-formed. The result is wrapped in a standard XML declaration and a root element, then indented two spaces per level so it's easy to read or diff. Everything happens in JavaScript running in your browser: nothing you paste is sent to a server, which makes it a quick way to check how a JSON payload, API response, or config file would look as XML before wiring up a real conversion pipeline.

Key benefits

Free, unlimited conversions with no signup
Handles nested objects and arrays of any depth
Automatically escapes reserved XML characters so the output stays well-formed
Runs entirely in your browser, your JSON is never sent to a server
Produces indented output that is easy to read and diff

Features

Recursive conversion of nested JSON objects into nested XML elements
Array items repeated as sibling elements sharing the array's key as the tag name
Automatic escaping of XML-reserved characters in string values
Standard XML declaration included at the top of the output
Two-space indentation for readable, well-formed markup

Popular use cases

Converting a JSON API response for a system that requires XML
Generating XML test fixtures from JSON data
Migrating configuration data from JSON to XML
Learning how a given JSON structure maps to its XML equivalent

How to use JSON to XML

1
Paste your JSON
Enter valid JSON into the input panel, or start from the sample data already filled in.
2
Convert
Click Convert to XML to parse the JSON and build the XML output.
3
Review the output
Check the right-hand panel; nested objects become nested elements and arrays repeat as sibling elements.
4
Copy the result
Use Copy XML to grab the converted markup for your file or API.

Frequently asked questions

How are arrays represented in the XML output?

Each array item is repeated as a sibling element with the same tag name as the array's key.

Does this handle deeply nested JSON?

Yes, the converter recursively processes nested objects and arrays to any depth.

Is my data uploaded anywhere?

No. The JSON is parsed and the XML string is assembled by JavaScript running in your browser, so an API response or payload you paste here is never transmitted.

Does the output include an XML declaration?

Yes. Every conversion is wrapped in a standard XML declaration followed by a root element containing your data.

What happens to reserved characters like an ampersand or a less-than sign inside a string value?

They are automatically escaped to their XML entity equivalents, so a value containing those characters still produces well-formed XML.
