Frequently asked questions

Is the output valid for Kubernetes?

Yes. The output is standard YAML 1.2 produced by js-yaml, the same library used across the Node ecosystem, so it is accepted by kubectl, Docker Compose and every mainstream CI system.

Can I control the indentation?

Yes — choose 2 or 4 spaces. Two spaces is the convention for Kubernetes and Docker Compose files.

Is my data uploaded to a server?

No. Every tool on this site runs entirely inside your browser using JavaScript. Your input never leaves your device and is never sent over the network, which means it is safe to paste production data, API responses and tokens.
