Tests transformations of appsettings.json files to validate configurations.

Appsettings.json Transform Tester

The Appsettings.json Transform Tester is a must-have tool for verifying transformations of appsettings.json files. It ensures your environment-specific configurations are correct before deployment.

What can it do?

Here’s how the Appsettings.json Transform Tester helps:

  • Tests transformations of appsettings.json files against a base configuration.
  • Highlights differences between the original and transformed files.
  • Validates the syntax of both the base and transformed JSON files.
  • Provides instant results directly in the browser without additional software.

What do I use it for?

I use the Appsettings.json Transform Tester in these cases:

  • Checking if my appsettings.json transformations for different environments (e.g., Development, Staging, Production) are correct.
  • Debugging issues with overridden settings in specific environments.
  • Ensuring consistency in configurations across multiple environments.
  • Testing how changes to the base configuration affect the transformed output.

Example of how it works

Base appsettings.json:

Transform file:

Resulting output:

I just load my base file and the transformation into the tool, and it instantly shows the resulting configuration. This saves me from deploying broken settings and ensures my environment-specific configurations work as expected.
