💣 Example of Broken and Messy JSON

Copy this ugly, invalid JSON into JSONLint or any formatter above and see it catch the issues:

{ name: "Alex", 
  "age": 25
  "skills": ["C++","Python", "HTML",
  "favoriteColor":"blue",
  "active": truuuu,
  hobbies: [ 'gaming', "coding" 'reading']
}

⚠️ Problems with this JSON:

Missing quotes around name
Missing comma after 25
Unclosed array brackets
Invalid boolean value truuuu
Mismatched quote types

🔧 Paste it into a tool to fix or format it cleanly.

💡 Pro Tip: When debugging APIs or web apps, drop your response into JSONLint first — it’ll instantly catch trailing commas, unescaped characters, or missing braces.
