What causes "Unexpected token" errors in JSON?
Common causes: trailing commas after the last item, single quotes instead of double quotes, unquoted keys, comments (JSON doesn't support comments), and missing commas between items. Our validator pinpoints the exact error location.
What is the difference between prettify and minify?
Prettifying adds indentation and line breaks to make JSON human-readable. Minifying removes all whitespace to reduce file size for production.
