JSON Standard Overview (RFC 8259)

JSON (JavaScript Object Notation) is a lightweight data-interchange format defined by RFC 8259. Property names must strictly be enclosed in double quotes ("), supporting strings, numbers, booleans, objects, arrays, and null.

Pretty Print vs. Minification

Pretty-printing inserts indentation and line breaks for human readability during debugging, whereas Minification eliminates all unnecessary whitespace to minimize payload size across API transfers.
