Why do you need a JSON Formatter? JSON (JavaScript Object Notation) is the de facto standard stringifier technique used by modern REST and GraphQL APIs. Unformatted, minified JSON is extremely dense and impossible for humans to parse reliably.
A "JSON Formatter" unminifies this code. It applies standard spacing (typically 2 or 4 space indentation) and aligns curly braces contextually. Furthermore, this tool helps spot syntax errors visually by immediately crashing on invalid JSON rules (such as trailing commas, unquoted keys, or single quotes).
