JSON Tool FAQs
Why does JSON formatting fail?
Common causes:
1. Syntax errors: Check missing quotes/commas/braces (e.g. {"key":value} should be {"key":"value"})
2. Escape characters: Use "Remove Escapes" for \" or \n
3. Comments present: JSON standard doesn't support // or /**/
4. Trailing commas: Remove commas after last property (e.g. {"a":1,})

Precautions for JSON-to-Code conversion?
Key notes:
1. Naming: Special chars auto-converted to camelCase (e.g. "user-name"→userName)
2. Type inference: Large numbers should use String type
3. Nested objects: Suggest splitting classes beyond 3 levels
4. Arrays: Toggle between List<T> and T[]
5. Dates: Manually add @JsonFormat annotations

How to fix remote JSON fetch failures?
Troubleshooting:
1. CORS: Ensure Access-Control-Allow-Origin header
2. HTTPS required: Only secure URLs supported
3. Timeouts: Download large JSON locally first
4. Authentication: Token-based APIs not supported
5. Validation: Check JSON validity before parsing
