About JSON Formatter

JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate. However, raw JSON generated by APIs is often minified into a single line, making it hard to inspect.

Features of this Formatter:

  • Format minified JSON to make it human-readable.
  • Minify formatted JSON to compress space for API requests.
  • Validate JSON strings to ensure correctness of keys, quotes, and commas.
  • One-click copy to clipboard.

Ensure your JSON conforms to standard specifications: string keys must be surrounded by double quotes, and trailing commas are not allowed.
