What formats can I convert between?

.env to JSON, YAML, Docker --env-file format, and Kubernetes ConfigMap YAML. Reverse conversion from JSON/YAML back to .env is also supported.

What does Generate Example do?

It strips all values from your .env and keeps only the keys with empty values or placeholder comments, creating a safe .env.example file to commit to version control.
