Instructions on Use

JSON (JavaScript Object Notation) is a lightweight data format that is easy for humans to read and for machines to parse. This tool helps you beautify and check your JSON for syntax errors.

  1. Paste your raw or minified JSON into the "Enter your JSON" box.
  2. Select your preferred indentation style from the options.
  3. Click the "Format & Validate" button. The tool will first check if the JSON is valid.
    • If the JSON is valid, a success message will appear, and the code will be formatted in the output box below.
    • If the JSON is invalid, a detailed error message will appear, helping you find the mistake in your code.

For example, a messy input like {"name":"John Doe","age":30,"isStudent":false,"courses":[{"title":"History","credits":3},{"title":"Math","credits":4}]} will be formatted into a clean, readable structure.
