Frequently Asked Questions

FAQs about YAML to JSON

What YAML features are supported?

This tool supports nested objects, arrays (dash notation), comments, and standard data types (strings, numbers, booleans, null). Flow sequences and complex YAML features may require a dedicated YAML library.

Are YAML comments preserved?

No. Comments are a YAML-only feature and are stripped during conversion since JSON does not support comments.

Can I convert Kubernetes manifests?

Yes, for standard YAML structures. Complex features like anchors and aliases may not be fully supported by this lightweight parser.

Why not use a full YAML library?

This tool uses a lightweight built-in parser to keep the page fast and avoid loading large dependencies. For complex YAML, consider a local tool with js-yaml.

Is my data safe?

Yes. All conversion happens locally in your browser.
