Taming JSON Data

JSON (JavaScript Object Notation) has become the de facto standard for data interchange on the web. However, raw JSON is often minified or poorly formatted, making it hard for humans to read.

Why Use a Formatter?

Pretty Print

Adds proper indentation and newlines to make the data structure visually clear and easy to scan.

Minification

Removes all unnecessary whitespace to reduce file size for production use.

Validation

Instantly checks for syntax errors like missing quotes or trailing commas that can break your application.

Common Syntax Rules

JSON is strict about its syntax. Here are a few rules to remember:

  • Keys must always be enclosed in double quotes.
  • Strings must use double quotes, not single quotes.
  • Trailing commas after the last item in an object or array are not allowed.
