How do I fix invalid JSON?
Start from the line number in the error message โ€” the actual mistake is usually on that line or the one just before it. Check for missing or extra commas, mismatched brackets or braces, single quotes that should be double quotes, and unquoted keys. Fix one error at a time and re-validate; a single missing bracket can cascade into many misleading errors further down the document.

JSON Checker - The JSON Validator | Check JSON Online
What causes โ€œUnexpected tokenโ€ errors in JSON?
An โ€œUnexpected tokenโ€ error means the parser hit a character it wasn't expecting. The most common causes are: a trailing comma after the last item in an object or array, single quotes instead of double quotes around strings or keys, unquoted property names, a missing comma between items, or unescaped special characters inside a string. Paste your JSON above and the error message will point to the line where the parser stopped.
