faq
Questions, answered.
01Is my YAML sent to a server?
No. Parsing runs locally in your browser, so manifests containing credentials or internal endpoints never leave your device.
02Why does my YAML fail to parse?
The usual suspects are tabs instead of spaces, inconsistent indentation, or a missing space after a colon. The error message points at the offending line.
03Is YAML to JSON free to use?
Yes, YAML to JSON is completely free, with no sign-up and no usage limits. It runs entirely in your browser, so your data never leaves your device.
