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

Minify JSON for production to reduce file size and improve loading times.

Common JSON Errors

1. Single Quotes

JSON requires double quotes for strings. Single quotes will cause validation errors.

❌ Wrong: {"name": 'John'}
✅ Correct: {"name": "John"}

2. Trailing Commas

JSON doesn't allow trailing commas after the last element in arrays or objects.

❌ Wrong: {"name": "John", "age": 30,}
✅ 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.
