Best Practices

1. Indentation

• Use 2 or 4 spaces for indentation
• Maintain consistency

2. Key Naming

• Use snake_case or camelCase
• Maintain consistency throughout the file

{
    "user_name": "snake_case style",
    "userName": "camelCase style"
}

3. Data Organization

• Group related fields
• Place important fields first

{
    "id": "001",
    "name": "Important fields first",
    "metadata": {
        "created_at": "2024-01-01",
        "updated_at": "2024-01-02"
    }
}

4. File Size

• Single file < 1MB optimal
• Consider pagination or splitting files for large data

Use Cases

• API response data preview
• Configuration file viewing
• Data structure review
• Debug data inspection
