Common Mistakes to Avoid

  • !Using tabs instead of spaces in YAML input, which causes parsing errors
  • !Forgetting that YAML treats unquoted yes/no as booleans, not strings
  • !Not quoting strings that start with special characters like @ or *

Limitations

  • –YAML anchors and aliases may not be preserved in the JSON output
  • –YAML-specific types like timestamps may convert to plain strings
  • –Multi-document YAML files may only convert the first document
