How to use the XML ↔ JSON Converter

Select the direction: XML → JSON or JSON → XML.
Paste your XML or JSON into the input box.
Click Convert. XML attributes are preserved with an @ prefix in the JSON output.
Copy the result to your clipboard.

How XML attributes are mapped to JSON

XML has two ways to store data: elements (<name>Alice</name>) and attributes (<user id="1">). JSON only has keys and values. This converter maps XML attributes to JSON keys prefixed with @:

<user id="1">Alice</user>
→ {"user": {"@id": "1", "#text": "Alice"}}

The #text key holds the text content of an element when it also has attributes or child elements. Pure text elements with no attributes are mapped directly to a string value.

XML to JSON, common use cases

Legacy API migration: older SOAP and REST APIs return XML; convert responses to JSON for modern JavaScript apps
RSS / Atom feeds: parse feed XML into JSON for processing or storage
Configuration files: some tools (Maven, Ant, Spring) use XML config; convert to JSON for other environments
SVG data: extract data from SVG documents for further processing

JSON to XML, when you need it

Integrating with systems that only accept XML input (ERP, EDI, SOAP services)
Generating XML sitemaps or configuration from JSON data sources
Round-tripping data: convert XML → JSON for editing, then JSON → XML to write back

Limitations

XML supports features with no direct JSON equivalent: processing instructions, DTDs, comments, and mixed content (text mixed with child elements). This tool focuses on data-oriented XML, elements and attributes, which covers the vast majority of real-world use cases.

Privacy

Conversion uses the browser's built-in XML parser. Nothing is uploaded or sent to any server.
