Q: Is my YAML data secure?
Yes. All processing happens entirely in your browser using the js-yaml library. No data is ever sent to any server.
Q: What YAML versions are supported?
This tool uses js-yaml which supports YAML 1.2 specification. It handles all standard YAML features including anchors, aliases, multi-line strings, and complex data types.
Q: Can I see the parsed structure?
Yes. When your YAML is valid, the tool displays the parsed JSON representation so you can verify the data structure.
Q: Does it show error line numbers?
Yes. When validation fails, the tool shows the exact line and column number where the error occurred, along with a descriptive error message.
Q: Can I validate multi-document YAML?
This tool validates single YAML documents. For multi-document YAML files (separated by ---), validate each document separately.
