Frequently asked questions

Does this tool upload my JSON?

No. The transformation runs in your browser. URL import contacts only the address you explicitly enter.

What happens when the JSON is invalid?

The editor marks the likely location and keeps stale output out of the result pane.

What does JSON to YAML produce?

It emits deterministic YAML with quoted ambiguous strings and preserved JSON values.

What limitation applies to JSON to YAML?

JSON has no anchors, comments, tags, or custom YAML types, so none can be created from the source.
