Human Readable
YAML's clean syntax with indentation makes it easier to read and edit than JSON for configuration files.

Frequently Asked Questions
How are JSON arrays converted to YAML?
JSON arrays are converted to YAML list format using dash (-) notation, maintaining the original order and nesting.
Are quotes preserved in YAML output?
YAML only quotes strings when necessary (e.g., special characters). Simple strings are unquoted for better readability.
Can I add comments to the generated YAML?
While the converter doesn't add comments, you can easily add them manually using the # symbol after conversion.
How are special characters handled?
Special characters are properly escaped and quoted in YAML to ensure the output is valid and parseable.
