What Is JSON Formatting?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. While JSON data is valid whether minified or formatted, properly formatted JSON is much easier to read, debug, and maintain.

Features

  • Format / Beautify: Adds proper indentation (2 spaces) and line breaks for readability
  • Minify: Removes all unnecessary whitespace to reduce file size
  • Validate: Checks if your JSON is syntactically correct and shows detailed error messages
