This command line tool allows you to convert a valid JSON object into "double underscore" notation environment variables for DotNet Core applications.

Use Cases

• Terraform injection of environment variables into dotnet core applications
• ...

Example

Passing in a JSON string such as {"test":1, "test2":[{"test3":3}]} will return

{
	"test":1,
	"test2__0__test3":3
}
