About JSON formatting
JSON (JavaScript Object Notation) is the most common data interchange format on the web. Raw JSON from APIs is often minified — all on one line with no spaces — which is hard to read. Beautifying adds consistent indentation so you can easily scan its structure.
Minifying removes all unnecessary whitespace, reducing file size for transmission. Validation checks that the text is syntactically correct JSON: proper bracket matching, quoted keys, comma placement and value types.
