What this does
Converts YAML into JSON. For example service: devtools followed by port: 4321becomes {"service": "devtools", "port": 4321}.
How it works
If your YAML has more than one document separated by ---, each document is converted and the result is a JSON array with one entry per document. A single document converts to a plain JSON object or value. Parse errors include the line number from the YAML parser. Use "Swap direction" to convert the other way without leaving the page.
