Convert SOAP XML to JSON: Free Online Converter
- SOAP XML can be pasted directly into the browser converter — SOAP envelope wrapper and all.
- The converter extracts the nested body content and maps it to JSON structure.
- Useful for developers working with legacy SOAP APIs who need the data in JSON format.

SOAP API responses arrive as XML with a specific envelope structure. Converting them to JSON — for logging, debugging, passing to a REST endpoint, or storing in a database — requires stripping the SOAP wrapper and mapping the payload to JSON format. The free Whale XML to JSON converter handles SOAP XML directly: paste the full response, including the SOAP envelope, and download clean JSON. No code, no server, no upload.
What Makes SOAP XML Different From Regular XML
SOAP (Simple Object Access Protocol) is an XML-based messaging protocol used extensively in enterprise web services — banking, insurance, healthcare, government systems, and older ERP and CRM integrations. SOAP APIs exchange data as XML, wrapped in a standard envelope structure.
A typical SOAP response looks like this: an outer <Envelope> element (often namespaced as soap:Envelope) containing a <Body> element, which contains the actual response data with its own element hierarchy.
The SOAP envelope and namespaces are protocol infrastructure — developers working with SOAP data often want just the payload inside the Body, converted to JSON for storage, processing, or passing to a modern REST-based system. The XML-to-JSON converter handles this: the envelope becomes a top-level JSON object, the body content maps to nested JSON, and namespace prefixes become part of the key names.
How to Convert a SOAP XML Response to JSON
Copy the full SOAP XML response — including the <soap:Envelope> wrapper. Paste it into the XML to JSON converter input area. Click Convert.
The converter processes the entire XML tree. The soap:Envelope element becomes a top-level key in the JSON output. Namespace prefixes like soap: or xsi: are preserved as part of the key names — "soap:Envelope" in the JSON.
XML attributes in the SOAP response (like xmlns namespace declarations) map to @attributeName keys in the JSON. The Body content — the actual payload — is nested under the Body key in the JSON output.
To extract just the payload, copy the JSON, paste it into a JSON editor or formatter, and navigate to the Body element. Most developers write a brief extraction script after this initial conversion step.

SOAP XML uses XML namespaces extensively. A response might have elements like <soap:Body>, <ns2:GetCustomerResponse>, or attributes like xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/".
In the JSON output: namespace prefixes become part of the key name. <soap:Body> becomes "soap:Body". Namespace declaration attributes become "@xmlns:soap" keys. This preserves the full structure without loss of information.
If you want cleaner key names without namespace prefixes, the standard approach is to strip the namespace prefixes from the XML before converting, or to write a brief post-processing step on the JSON output to rename keys. For debugging and quick data inspection, the namespace-qualified keys are usually fine — they map exactly to the original SOAP structure.
Common Use Cases for SOAP to JSON Conversion
Legacy system integration: Older banking, insurance, and government APIs often only speak SOAP. When connecting them to a modern REST microservice architecture, converting SOAP responses to JSON is a standard middleware task. The browser converter handles one-off debugging during development; production systems use automated libraries.
Data extraction: Pulling specific values from a SOAP response for logging, reporting, or loading into a database. Converting to JSON first makes the data easier to navigate and query with standard tools.
API testing and debugging: When a SOAP API returns unexpected data, converting the response to JSON lets you inspect it in a JSON viewer or formatter and spot the issue quickly.
Documentation: Showing a SOAP API's response structure as JSON in internal documentation is often clearer for developers who primarily work with REST APIs.

Open Free XML to JSON ConverterFrequently Asked Questions
Does the converter handle SOAP faults?
Yes. SOAP faults are XML like any other SOAP response. The soap:Fault element and its children map to JSON keys and values the same way as a normal response.
Can I use this to convert SOAP to a REST JSON format automatically?
The converter produces JSON that mirrors the XML structure. Transforming that to a specific REST API's JSON schema requires additional mapping — the converter gives you the data in JSON, not a fully reformatted API payload.
What about SOAP 1.1 vs SOAP 1.2?
Both use XML with the same basic envelope structure. The namespace URIs differ, but the converter handles both — it processes XML regardless of the SOAP version.
Is this useful for WSDLs?
WSDLs are also XML and can be converted to JSON for inspection. However, WSDL JSON output is complex and most developers prefer to read WSDLs directly as XML.
