Background Knowledge

JSON (JavaScript Object Notation) is a text-based open standard format used to represent structured data. It was first proposed by Douglas Crockford in 2001 and quickly became one of the standard formats for data exchange on the internet. JSON's design is inspired by JavaScript's object literal syntax, but it is independent of any programming language, and almost all modern programming languages support JSON parsing and generation.

The main features of JSON include:

  • Lightweight: JSON uses a simple text format that is easy to read and write.
  • Self-descriptive: JSON data structures consist of key-value pairs, which are highly self-descriptive.
  • Language-independent: Although JSON's syntax is derived from JavaScript, it is language-agnostic and widely supported across various languages and platforms.
  • Easy to parse: JSON's format is simple, making it fast to parse and suitable for network transmission.

In web development, JSON is commonly used to transmit data between clients and servers. Due to its structured and readable nature, JSON is also often used for configuration files and data storage.

Usage

  1. Input JSON Data: Enter or paste your JSON data into the editor on the left.
  2. Set Indent Size: You can set the indent level of the JSON data by adjusting the "Indent size" input box, with a range of 0 to 10.
  3. Sort Keys: If you want the keys of the JSON object to be sorted alphabetically, you can enable the "Sort keys" switch.
  4. View Formatted Result: The formatted JSON data will be displayed in the editor on the right, where you can copy or further edit it.

This tool is designed to help developers and data analysts quickly format and beautify JSON data for better readability and debugging.
