JSON Formatter & Validator

JSON (JavaScript Object Notation) is the standard data format for the web. However, raw JSON from APIs is often minified (squashed into one line), making it impossible to read.

What this tool does

  • Beautify: Adds proper indentation (2 spaces) and newlines to make the code readable for humans.
  • Minify: Removes all unnecessary whitespace to reduce file size for production use.
  • Validate: Checks for syntax errors like missing commas or quotes and points out exactly where the error is.
