❓Frequently Asked Questions

Is YAML always better than JSON for configs?

Not always. JSON is stricter and better for APIs, while YAML shines in human-edited configuration files.

Can YAML handle comments?

Yes. YAML supports inline and block comments, making it easier to document configurations.

What’s the biggest pitfall in YAML?

Indentation errors. Always use spaces consistently and avoid mixing tabs.

Does the converter support large JSON files?

Yes. It can handle large JSON inputs and generate YAML without performance issues.

Can YAML represent multiple documents in one file?

Yes. YAML supports multi-document files separated by '---', which is useful for Kubernetes manifests.

How do I avoid type confusion in YAML (e.g., 'yes' being treated as boolean)?

Quote strings explicitly to prevent unintended type casting. For example, use "yes" instead of yes.

Is YAML slower than JSON for parsing?

Generally yes, JSON parsing is faster, but YAML is chosen for readability and flexibility in configuration files.

Can I convert YAML back to JSON easily?

Absolutely. Most libraries and CLI tools support bidirectional conversion, making it simple to switch formats.
