YAML to JSON Conversion

This tool converts common YAML patterns to JSON: indented mappings become objects, dash-prefixed sequences become arrays, and unquoted scalars are automatically typed (numbers, booleans, and null). Quoted strings are unquoted in the output.

Note: This is a lightweight browser-based parser that handles the most common YAML patterns. Complex YAML features like anchors (&), aliases (*), block scalars (|, >), and multi-document files are not supported.
