Proper Quoting: Quote strings with special characters
Clear Structure: Use meaningful keys and structure
Comments: Add comments for complex configurations

JSON Best Practices

Valid Syntax: Ensure proper JSON syntax
Consistent Formatting: Use consistent indentation
Meaningful Keys: Use descriptive property names
Data Types: Use appropriate data types

Conversion Best Practices

Validate Input: Always validate YAML before conversion
Test Output: Verify JSON output is correct
Handle Errors: Implement proper error handling
Preserve Data: Ensure no data loss during conversion
