JSON Formatter

Format and validate your JSON data with proper indentation.

What is JSON?

  • JSON (JavaScript Object Notation): A lightweight data interchange format.
  • Easy for humans to read and write, easy for machines to parse and generate.
  • Widely used for APIs, configuration files, and data storage.
  • More concise than XML, making it the web development standard.

JSON Syntax Basics

β€’ Objects: Curly braces with key-value pairs, e.g. object notation

β€’ Arrays: Square brackets, comma-separated values

β€’ Strings: Must use double quotes (single quotes not allowed)

β€’ Numbers: Written without quotes (integers and decimals)

β€’ Booleans: true or false (lowercase only)

β€’ null: Represents empty value (lowercase)

Common JSON Errors

  • β€’ Trailing comma: Comma after the last item causes errors
  • β€’ Single quotes: Strings must use double quotes only
  • β€’ Comments: JSON doesn't support comments
  • β€’ Unquoted keys: All keys must be strings (quoted)
  • β€’ undefined: null is valid, but undefined is not

JSON Use Cases

  • β€’ REST APIs: Server-client data communication
  • β€’ Config Files: package.json, tsconfig.json, etc.
  • β€’ NoSQL Databases: MongoDB, Firebase data storage
  • β€’ Local Storage: Browser data persistence
