Questions and answers
Does it handle anchors, aliases, and merge keys?
Yes, it supports full YAML 1.2 parsing including anchors, aliases, and merge keys, which are resolved into plain values in the JSON output since JSON has no reference syntax.
Is it safe to paste configs with secrets?
Yes, the conversion runs entirely in your browser with nothing transmitted, logged, or stored. You can even disconnect from the internet and the converter continues working.
What about multi-document YAML with --- separators?
Multi-document YAML streams convert to a JSON array with one element per document, which is common in Kubernetes manifests.
Can I convert JSON to YAML?
Yes, you can switch direction with one click, which is handy for turning API responses into readable config files.
