Why convert YAML to JSON?
YAML is what Kubernetes manifests, GitHub Actions workflows and Docker Compose files are written in, while most APIs and test fixtures expect JSON. Converting locally means sensitive config never gets pasted into a random website.
Are my YAML files uploaded anywhere?
No. The conversion runs inside your browser using your own device's processing power, so the file never leaves your computer or phone and nothing is stored on a server.
