What is SOAP Formatter?

SOAP Formatter pretty-prints SOAP XML messages — the standard protocol format used by web services. A raw SOAP message is often a single-line blob of XML with no whitespace. This formatter normalises the whitespace and indents each element so the soap:Envelope, soap:Header, soap:Body, and nested payload elements are clearly visible. It uses the same XML formatting engine as the XML Beautifier and handles both SOAP 1.1 (schemas.xmlsoap.org) and SOAP 1.2 (www.w3.org/2003/05/soap-envelope) namespace prefixes.

Example Input and Output

A single-line SOAP request is expanded with proper XML indentation.

Compact SOAP
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><GetUser><UserId>1</UserId></GetUser></soap:Body></soap:Envelope>
Formatted SOAP
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetUser>
      <UserId>1</UserId>
    </GetUser>
  </soap:Body>
</soap:Envelope>

Privacy

SOAP messages are formatted locally in the browser and are not uploaded.

Frequently Asked Questions

Does this validate SOAP structure?

No. It formats XML for readability only. Use a SOAP testing tool like SoapUI or Postman to validate message structure against a WSDL.

Does it handle SOAP attachments (MTOM)?

MTOM attachments are binary data outside the XML envelope. The formatter handles the XML part only and ignores MIME boundaries.

Can it format SOAP 1.2 messages?

Yes. Both SOAP 1.1 (http://schemas.xmlsoap.org/soap/envelope/) and SOAP 1.2 (http://www.w3.org/2003/05/soap-envelope) namespaces are treated as regular XML namespaces.

Is my SOAP message uploaded anywhere?

No. Formatting runs entirely in your browser.
