About JSON Formatter

This tool allows you to format, validate, and beautify your JSON (JavaScript Object Notation) data to make it more readable and easier to work with.

Features:

  • Format/Beautify: Make JSON data human-readable with proper indentation
  • Validate: Check if your JSON is valid and error-free
  • Minify: Remove all whitespace to reduce file size
  • Line Numbers: Easy to reference specific lines in your JSON
  • Customizable Indentation: Choose your preferred indent size

JSON Syntax Rules:

  • Data is in name/value pairs
  • Data is separated by commas
  • Curly braces {} hold objects
  • Square brackets [] hold arrays
  • Names require double quotes

Common JSON Errors:

  • Missing or extra commas
  • Missing closing brackets or braces
  • Improperly quoted property names
  • Trailing commas (not allowed in JSON)
  • Single quotes instead of double quotes
  • JavaScript comments (not allowed in JSON)
