FormatJSONOnline

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy to read and write for humans while being equally easy for machines to parse and generate. Used primarily for transmitting data in web applications, it is structured in key-value pairs, such as:

{
  "name": "John Doe",
  "age": 30,
  "isStudent": false,
  "courses": ["Math", "Science"],
  "address": {
      "street": "123 Main St",
      "city": "Boston"
  }
}
