Frequently asked questions
Is my data uploaded?
Nothing is uploaded. This tool runs entirely in your browser, so your data is processed on your own device and never sent to a server.
Is it free?
Yes — it is free with no sign-up, no watermark and no account-based quota. Your browser, device memory and the bench's stated file limits still determine how much it can process at once.
Can it convert in both directions?
Yes. Paste JSON to produce YAML, or paste YAML to produce JSON, then copy the converted configuration.
