SOAP to JSON

SOAP to JSON Converter Online

The SOAP to JSON converter unwraps a SOAP envelope and turns the payload into clean JSON. Paste a request or response captured from SoapUI, a proxy log, or your application, and get the Body as a JSON object you can read, diff, or reuse in a REST client or JavaScript code.

What the converter does

1. It checks that the root element is a SOAP Envelope and finds its Body — so you get a clear error when you paste plain XML or an HTML error page by mistake.
2. The Body is converted element by element. Namespace prefixes are stripped, attributes become @name keys, and repeated elements become arrays.
3. With Detect numbers & booleans on, values like 34.50 and true become JSON numbers and booleans; turn it off to keep every value as a string exactly as sent on the wire.

Header and version

By default only the Body content is returned — usually what you want when you are mapping a legacy service to a modern API. Switch on Include SOAP header & version to get an object with soapVersion, header (WS-Security tokens, correlation IDs, session data) and body. That view is handy when debugging authentication problems or tracing requests across systems.

Use cases

• Inspecting responses of banking, logistics, or government SOAP services in a readable form.
• Writing a REST façade: convert real responses to JSON to design the new API's schema.
• Creating test fixtures and mock data from recorded SOAP traffic.
• Comparing two responses with the JSON Diff tool after conversion.

Limitations

The tool converts the message you paste; it does not call the service. Binary attachments (MTOM/SwA) are not part of the XML envelope and therefore are not included.
