What is JSON Beautification?
JSON beautification — also called formatting or pretty printing — is the process of transforming compact, machine-optimized JSON into an indented, structured format that humans can easily read and understand. A JSON beautifier adds line breaks after each key-value pair, indents nested objects and arrays, and aligns colons for maximum readability.
