FAQ
Q: Is my data secure?
Yes! All conversion happens entirely in your browser. Your data never leaves your device.
Q: What YAML features are supported?
The tool supports standard YAML 1.2 syntax including anchors, aliases, multi-line strings, nested objects, arrays, and all standard YAML data types.
Q: Can I convert multiple YAML files at once?
Yes! Upload several YAML files together and each will be converted to JSON with clearly labeled sections in the output preview.
Q: What if my YAML has comments?
YAML comments (lines starting with #) are supported in the input and will be ignored during conversion, as JSON doesn't support comments.
