WSDL Formatter: Format & Beautify WSDL Online
WSDL format is XML: a valid WSDL document follows the W3C WSDL 1.1 or 2.0 schema with definitions, types, messages, port types, bindings, and services. This formatter pretty-prints any WSDL with consistent indentation so the service contract is actually readable, and unlike generic XML formatters, it understands what the sections mean.
How it works
- 1
Paste your WSDL document into the editor.
- 2
Click Format: indentation is normalized (idempotent: formatting twice never double-indents).
- 3
Copy the result, or switch to Minify to strip whitespace for transmission.
Frequently asked questions
What is the WSDL format?
WSDL is an XML format standardized by the W3C for describing web services. A WSDL 1.1 document has five core sections: types (XML Schema data definitions), message (the data being exchanged), portType (operations), binding (protocol details, usually SOAP), and service (the endpoint address).
Is a WSDL file just XML?
Yes. Every WSDL file is a well-formed XML document, so any XML tool can read it. What makes it WSDL is conformance to the WSDL namespace and schema (http://schemas.xmlsoap.org/wsdl/), which defines the meaning of its elements.
Why does my formatted WSDL keep growing in size?
Naive formatters add new indentation on top of existing whitespace each time you run them. This formatter normalizes whitespace between tags before re-indenting, so formatting is idempotent: running it ten times produces the same output as running it once.
Can I validate the WSDL while formatting?
The formatter checks well-formedness automatically; malformed XML is reported with the parser error instead of being silently mangled. For deeper structural analysis, run the document through the WSDL Analyzer.
