FAQ

Does this run locally in my browser?

Yes. All parsing and conversion happens in your browser, and files are not uploaded.

Why can conversions fail for some YAML?

YAML supports types that JSON does not. Use Strict JSON to reject them or Coerce mode to convert.

What are the keyboard shortcuts?

Ctrl+Enter to convert, Ctrl+L to clear, and Ctrl+S to download (Cmd on macOS).

Why is output capped at 25MB?

Large outputs can cause memory spikes. Reduce input size for massive conversions.
