Extract text from Web test files (WEBTEST)
To convert WEBTEST Web tests to another format, you need Visual Studio or other Developer software.
To convert other file formats to the "Web Performance Test File" file type, you need software like Visual Studio or a similar tool.
A .WEBTEST file is an XML-based script created by Microsoft Visual Studio to define and execute web performance tests. These files contain recorded HTTP requests, form parameters, and validation rules used to simulate user traffic against web applications. You can learn more about this process on the Web testing Wikipedia page.
Opening these files natively requires a heavy and expensive installation of Visual Studio. A critical disadvantage of the .WEBTEST format is that it is essentially a legacy format. Microsoft officially deprecated its web performance and load testing features starting with Visual Studio 2019. This forces QA teams to migrate away from these proprietary files, as they are not supported by web browsers and cannot be executed natively outside the Microsoft ecosystem.
To preserve testing logic, you should convert these files to XML to extract raw test data, or migrate the contents to JSON or JMX formats to run them in modern, open-source testing tools.
This format is notoriously difficult to convert directly because the XML structure relies on a proprietary Microsoft testing schema. Standard online converters fail to translate these specific nodes into functional scripts for other platforms.
Convert.Guru analyzes your WEBTEST file, detects the exact format, and lets you read the text inside.
If you want to convert WEBTEST file to , you can use Visual Studio or similar software from the "Web Performance Testing" category. In the File menu, look for Save As… or Export….

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 WEBTEST converter.
