Frequently asked questions
Does it catch indentation errors?
Yes: if the YAML isn't valid, we tell you instead of producing wrong JSON.
Does it support YAML anchors and references?
Yes, anchors (&) and aliases (*) are resolved and expanded in the resulting JSON.
What about comments?
JSON doesn't support comments, so they're dropped in the conversion.
Does it convert multiple documents (---) at once?
The first document is converted; split manually if your file contains several.
