## Questions

### What happens to a non-string key?

JSON requires string keys, so numeric and boolean keys are converted to their string form. That is a real difference between the two formats, not a bug.

### Are duplicate keys allowed?

No. YAML permits them but almost every parser takes the last one silently, which hides mistakes. This tool reports them instead.
