Convert JSON to XML for legacy system integrations

Bridge JSON apps to XML-only systems
Plenty of enterprise integrations still require XML — SOAP services, government APIs, and legacy B2B feeds, to name a few. Converting JSON to well-formed XML gives you a document that includes the standard XML declaration, escaped values, and a sensible mapping between objects, arrays, and elements.
Use the converter when you need to
Send data to a SOAP or legacy API
Many backend systems still accept only XML — convert your JSON payload before wrapping it in a SOAP envelope.
Generate XML feeds for partners
B2B partners often expect XML feeds for product, order, or pricing data — produce them from your JSON source of truth.
Integrate with government or banking endpoints
Regulatory and financial APIs often require XML — bridge the gap without maintaining a second data model.
How to convert JSON to XML quickly
- 1
Paste the JSON document into the editor.
- 2
Click Convert to produce well-formed XML with a root element and standard declaration.
- 3
Copy the XML or download it for use in your integration.
Keep going
Convert XML back to JSON
Process XML responses from the same legacy systems by converting them to JSON.
Convert to YAML instead
Pick YAML when the destination is a DevOps tool rather than a SOAP service.
Format JSON before converting
Clean up the source so the resulting XML structure is easier to scan.
Render as an HTML table
Display the same data as a browser-friendly table rather than XML.
Common JSON-to-XML workflows
Convert your JSON request to XML and slot it into the SOAP body without writing a custom serializer.
Generate the partner-required XML feed nightly from your JSON-based internal API.
Keep your modern code in JSON and convert at the boundary while you replace the old system over time.

Frequently Asked Questions
XML is still required by many enterprise systems, SOAP APIs, and legacy integrations. If you're working with a system that only accepts XML, this tool converts your JSON data into well-formed XML instantly.
Each array item becomes a repeated XML element. For example, {"items":[1,2,3]} becomes <items>1</items><items>2</items><items>3</items> wrapped in a root element.
Yes, the output includes the standard XML declaration <?xml version="1.0" encoding="UTF-8"?> at the top, making it ready for direct use in XML-consuming applications.
