To make things easy for you, we will explain how to create a JSON file on your Mac computer using different text editors.

What Is a JSON File?

JSON, JavaScript Object Notation, stores JavaScript objects in a text format for transporting them between computer servers, regardless of the programming language or device dependency.  

The data types used in JSON are the following.

  • Strings: Used in double-quotes.
  • Numbers: Positive or negative without using double quotes.
  • Booleans: True or False values.
  • Arrays: Data to be put in strings or numbers format in square brackets.
  • Objects: Creation of JavaScript objects with key value pairs using curly brackets.
