Wizdler is a Chrome extension developed by Peter Prikryl that simplifies the process of parsing WSDL files and generating SOAP messages. With Wizdler, you can easily view the available services and operations of a WSDL file, click on an operation to generate a SOAP request, and view the response. Additionally, you have the ability to download the WSDL and external XSD files in a single ZIP file.

To use Wizdler, simply navigate to a webpage that contains a WSDL file, and the extension will automatically recognize and display the available services and operations. By clicking on an operation, you can edit the pre-generated SOAP message and send it to see the response. You can also edit HTTP headers using the menu near the "Go" button. The extension provides a convenient tabbed interface for easy switching between the request and response editors.

Wizdler also offers additional features such as the ability to remember your last request, support for authentication methods like HTTP Basic, WSSE PasswordText, and WSSE PasswordDigest, and the option to buy the developer a beer using the provided PayPal link.

Overall, Wizdler is a useful tool for developers working with SOAP services. It provides a simple and intuitive interface for parsing WSDL files, generating SOAP requests, and viewing responses. The extension is available for free on the Chrome Web Store and can be found on GitHub for bug reporting and feature requests.
