faq
Questions, answered.
01Is my JSON sent to a server?
No. The conversion runs locally in your browser, so configs containing keys, tokens or internal URLs never leave your device.
02Why is a value quoted in the output?
YAML quotes values that would otherwise change meaning, like the string "y" (which unquoted can mean true in old YAML) or strings that look like numbers. That quoting keeps the data identical.
03Is JSON to YAML free to use?
Yes, JSON to YAML is completely free, with no sign-up and no usage limits. It runs entirely in your browser, so your data never leaves your device.
