Similar to Postman's JSON.stringify function, this will convert the JSON response of an API call into a string of text which can then be used to build scripts that can parse out the response without having to create the API call over and over. It can then be saved anywhere and easily converted back into JSON script anytime.
(Note: Sometimes the Evaluate function will need to evaluate the string when converting it back to JSON)
