Why is my JSON invalid?
Common causes are trailing commas, single quotes instead of double quotes, and unquoted keys. The formatter points you at the first parse error.
What's the point of minifying JSON?
Minified JSON strips whitespace to shrink payloads for transport. Pretty-printing does the reverse for readability when debugging.
