Use the parser when you want a quick syntax check plus formatted output from the parsed value.

The parser is focused on determining whether the JSON is valid according to native browser parsing rules.

Valid input is pretty-printed so nested objects and arrays are much easier to scan.

Single quotes, comments, and trailing commas still fail here because standard JSON does not allow them.
