Background Knowledge

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.

Formatting JSON makes it more readable by adding proper indentation and line breaks, which is especially helpful when working with complex or nested data structures.

This tool helps you format and validate JSON data, making it easier to read, debug, and share. It also allows you to sort object keys alphabetically for better organization.
