Understanding JSON & Formatting

What is JSON?

JavaScript Object Notation (JSON) is a lightweight, text-based standard for structured data interchange. It represents data using key-value pairs, arrays, objects, strings, numbers, booleans, and null values.

Why Beautify JSON?

Raw API payloads are often compressed or stripped of whitespace to save bandwidth. Formatting (beautifying) adds proper line breaks and nesting indentation, making complex payloads easily human-readable and simple to debug.

Minification vs. Formatting

Formatting adds spacing to improve readability for developers during debugging. Minification removes unnecessary spaces and newlines to optimize payload size for network transmission.
