Key capabilities:
- Robust YAML parsing supporting nested keys, sequences, multiline strings, and scalars
- Configurable JSON output indentation (2 spaces, 4 spaces, or compact minified)
- Syntax error diagnostics detecting indentation errors and invalid YAML syntax
- Direct client-side execution in your browser with zero network transmission
Tips:
- Ensure your YAML uses consistent 2-space indentation without tab characters before converting.
- Use 2-space JSON formatting for human readability or 0-space minification for production APIs.
- Click the Copy button to immediately paste the resulting JSON into your application codebase.
