About WSDL files
A .WSDL file is an XML-based document used to describe the functionality of a network service, specifically within the SOAP (Simple Object Access Protocol) framework. It defines the available methods, data types, and endpoints required for applications to communicate with the service. While standard for legacy enterprise systems and Apache Axis implementations, .WSDL files are notorious for being verbose and difficult for humans to read. Developers often struggle with the raw XML syntax when trying to quickly understand an API's capabilities without a dedicated IDE like SoapUI or Oracle JDeveloper. Furthermore, modern web development has largely shifted toward RESTful architectures, making .WSDL files incompatible with many current tools designed for JSON or YAML. To make the data accessible or to migrate legacy services, users frequently convert .WSDL files to HTML or PDF for readable documentation, or to OpenAPI formats (JSON/YAML) for integration with modern API gateways.
Convert.Guru analyzes your WSDL file, detects the exact format, and lets you read the text inside.
If you want to convert WSDL file to XSD, XML, JSON, HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP or JSPX, you can use SoapUI or similar software from the "Web Service API Definition" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to WSDL, try SoapUI or another comparable tool in the "Web Service API Definition" category.
The WSDL Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WSDL converter.
