Frequently Asked Questions

Can this convert YAML back to JSON too?

Yes. The swap button flips the tool into YAML→JSON mode, swaps the current input/output text, and updates the labels and button text.

Will it handle full YAML features like anchors or block scalars?

No. The parser is intentionally minimal: simple key/value pairs, lists, nested indentation, quoted strings, booleans, nulls, and basic numbers.

Why are some strings quoted in the YAML output?

Strings with special YAML-significant characters, newlines, leading or trailing spaces, or empty content are JSON-quoted so they round-trip safely.

Do comments or yes/no values survive when converting YAML to JSON?

Comment lines are ignored. yes/no map to true/false, and ~ maps to null.

Does it convert live, or only after clicking the button?

It auto-converts about 400ms after input changes. The button just runs the current mode immediately.
