JSON Best Practices
Proper Formatting
Use double quotes for strings, avoid trailing commas, and maintain consistent indentation for readability.
Data Types
JSON supports strings, numbers, booleans, arrays, objects, and null. Ensure correct data type usage.
Validation
Always validate JSON before using in production. Our validator provides detailed error reporting.
Performance

Common JSON Errors
1. Single Quotes
JSON requires double quotes for strings. Single quotes will cause validation errors.
✅ Correct: {"name": "John"}
2. Trailing Commas
JSON doesn't allow trailing commas after the last element in arrays or objects.
✅ Correct: {"name": "John", "age": 30}
3. Comments
JSON doesn't support comments. Remove all comment syntax before validation.
4. Undefined Values
Use null instead of undefined for missing values in JSON.
