Tips & Best Practices

  • JSON must be valid - all strings must be in double quotes, not single quotes.
  • Trailing commas are not allowed in JSON.
  • Use Format for readability and debugging, Minify for production/API use.
  • The formatter automatically detects and highlights syntax errors.
  • Perfect for API development, configuration files, and data processing.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is widely used in web development for transmitting data between a server and a web application.

Why Format JSON?

Raw JSON data is often minified (compressed) to save space, making it difficult to read. A JSON Formatter takes this raw data and organizes it with proper indentation and line breaks, making the structure clear and readable. This is essential for debugging and understanding complex data structures.

Validate and Minify

In addition to formatting, our tool validates your JSON to ensure it follows the correct syntax, helping you catch errors quickly. You can also 'Minify' your JSON, removing unnecessary whitespace to reduce file size for production use.
