Conversion Tips

  • â€ĸYAML comments will be lost when converting to other formats
  • â€ĸNested structures are flattened when converting to CSV using dot notation
  • â€ĸTOML doesn't support null values - remove them before converting
  • â€ĸXML attributes use @ prefix (e.g., @id) when converting to JSON/YAML
