Conversion Note

YAML comments and some advanced YAML features (like anchors and aliases) will be processed but not preserved in the JSON output, as JSON doesn't support these features. The data structure and values will be maintained.

All processing happens locally in your browser. Your data never leaves your computer, ensuring complete privacy and security.
