test-json: Test if a string from stdin is in JSON format.
$ '${string}' | Test-Json
try on your machine
This command is written in PowerShell scripting language.
The first part of the command '${string}' is a placeholder for a string value. The string can be any value that you want to process as JSON.
The vertical bar '|' is known as the "pipe" operator in PowerShell. It is used to send the output of one command as input to another command.
The second part of the command 'Test-Json' is a PowerShell commandlet (a built-in command) that validates whether a given string is in JSON format or not. It checks if the string can be successfully parsed as JSON without any errors.
In summary, the command takes the value of '${string}' and passes it as input to the 'Test-Json' commandlet, which then checks if the input string is valid JSON or not.
