Frequently Asked Questions

Does this use external libraries?

No. JSON → YAML conversion is implemented with a recursive serializer, and basic YAML → JSON parsing handles common structures, all without dependencies.

What YAML features are supported for parsing?

The YAML parser handles key-value pairs, nested objects (indented), arrays (using -), strings, numbers, booleans, and null. Complex features like anchors or multi-line strings require a full library.

Can I swap between JSON and YAML?

Yes. Click Swap to move the output back to the input and switch the conversion direction automatically.
