Fix "Unexpected token } in JSON" Error

The "Unexpected token } in JSON" error typically occurs when there's a trailing comma before a closing brace, or when JSON structure is malformed. This is one of the most common JSON syntax errors.

Common Causes

• Trailing comma before closing brace }
• Trailing comma before closing bracket ]
• Extra commas in JSON structure
• Missing quotes around keys or values

Broken JSON Example

{
  "name": "John",
  "age": 30,  ← Trailing comma error
}

{
  "name": "John",
  "age": 30
}
