WSDL Analyzer: Inspect Any WSDL in Seconds
A WSDL analyzer parses a Web Services Description Language document and shows you everything the service exposes: services, ports, operations, and the exact input and output each operation expects. Paste a WSDL URL or upload a file, and this tool extracts the full service contract, scores its quality, and generates ready-to-send SOAP requests and client code.
Every WSDL, SOAP & XML tool you need
Each tool runs free in your browser with no signup, and they hand work to each other, so an analysis becomes a test becomes working client code.
WSDL Tools
Format WSDL files online. WSDL-aware beautifier with proper indentation, minifier, and structure highlights. Free, no signup, runs in your browser.
Compare two WSDL files or URLs online. See added, removed, and changed operations with breaking-change detail. The only browser-based WSDL diff. Free.
Convert WSDL to readable XML online: format the document, extract endpoints, schemas and operations, or convert to JSON. Free, no install required.
SOAP Tools
Format SOAP XML online: requests, responses, and full envelopes. Envelope-aware beautifier with validation. Free, no signup, runs in seconds.
Send SOAP requests online: endpoint, SOAPAction, custom headers, timeout. Response status, timing, headers and body inline. History & environments. Free.
XML Tools
Free XML formatter: beautify, pretty-print, tidy and indent XML online, or minify it to one line. Idempotent formatting, no signup, no upload limit.
Validate XML online: well-formedness check with exact error messages and fixes, document statistics, and namespace report. Free, with nothing uploaded.
Analyze XML online: element counts, depth, namespaces, attributes, size stats and well-formedness with a structure health report. Free, in-browser.
Compare two XML files online. Format-aware diff that ignores whitespace differences and highlights added, removed, and changed lines. Free, no upload.
Parse XML online into an explorable tree: elements, attributes, text and namespaces, plus parse-error diagnosis. Free and browser-based, no signup.
Test XML online: well-formedness testing, structure stats, XPath-style element lookup, and live endpoint testing for XML APIs. Free, no signup.
Converters
Convert XML to JSON online. Attributes preserved as @attributes, repeated elements become arrays. Free and browser-based, with nothing uploaded.
Convert JSON to XML online. Objects become elements, arrays become repeated elements, values are escaped correctly. Free and browser-based.
Create XML online with a form-based generator: build elements, attributes and nesting visually, or generate SOAP envelopes from WSDL schemas. Free.
How it works
- 1
Paste a WSDL URL (ending in ?wsdl) or upload a .wsdl/.xml file.
- 2
Click Analyze WSDL: services, ports, and operations appear with a health score.
- 3
Copy the generated SOAP request for any operation, generate client code, or send it live with the built-in SOAP tester.
Frequently asked questions
What is a WSDL file?
A WSDL (Web Services Description Language) file is an XML document that describes a SOAP web service: the operations it offers, the messages each operation expects and returns, the data types used, and the endpoint address where the service listens. It is the machine-readable contract between a SOAP service and its clients.
How do I analyze a WSDL by URL?
Paste the full service URL ending in ?wsdl (for example https://example.com/service.asmx?wsdl) into the input above and click Analyze. The tool fetches the document server-side, parses it with a full XML-schema-aware parser, and lists every service, port, and operation it defines.
Is my WSDL file stored anywhere?
No. WSDL documents are parsed in memory and discarded. Nothing you analyze is stored, logged with content, or shared. Only an anonymous counter of total analyses is kept.
What does the WSDL health score mean?
The health score (0 to 100) flags common quality problems: generic auto-generated parameter names like arg0, string-only typing, and missing documentation. A high score means the contract is explicit and easy for clients to consume.
Can I test an operation directly from the analysis?
Yes. Every operation has a Test this Operation button that pre-fills the SOAP tester with the endpoint, SOAPAction, and a request template, and a Build Request form that generates the XML from the operation's actual schema types.
