Web.config Transformation Tester

What can it do?

Web.config Transformations can be both a powerful and challenging language to work with. With XDT, creating Web.config files for different configurations of your web applications requires nothing more than a bit of XML. Throw away homemade scripts to replace the content inside your configuration files and start writing transformations instead. Using the elmah.io Transformation Tester, previewing your changes is easier than ever. By inputting your original Web.config file and your transformation file, elmah.io will generate a nice diff to show you exactly which changes your transformation file is causing.
