JSON.parse errors are famous for pointing at the wrong character, usually a line or two after the real mistake. A validator that names the actual problem saves the longest five minutes of the day.
Paste your JSON and it flags broken brackets and stray commas with a readable error message, then offers pretty or minified output. When an API response will not parse, run it through here before you blame the API.
