What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It's based on a subset of the JavaScript programming language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is language-independent but uses conventions familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, and Python. These properties make JSON an ideal data-interchange language.

JSON Data Types

JSON supports these basic data types:

  • Number: Represents numeric values (e.g., 42, 3.14, -10).
  • String: Represents a sequence of Unicode characters enclosed in double quotes (e.g., "hello", "JSON").
  • Boolean: Represents either true or false.
  • Array: An ordered list of values enclosed in square brackets (e.g., [1, 2, 3], ["apple", "banana", "cherry"]).
  • Object: A collection of key-value pairs enclosed in curly braces (e.g., {"name": "John", "age": 30}).
  • Null: Represents an empty value.

Why Use JSON Prettier?

JSON data is often minified or compressed, which removes unnecessary whitespace to reduce file size. While useful for storage and transmission, this makes the data difficult to read. A JSON Prettier tool formats the data by adding indentation and line breaks, making it easier to understand and work with.

You can also convert XML to JSON or YAML to JSON.
