Frequently Asked Questions
What is a .env file?
A .env file stores environment variables as KEY=value pairs, one per line. It's commonly used for configuration that varies between environments.
How are multi-line values handled?
Multi-line values should be quoted. In JSON output, newlines are preserved. In .env output, they're escaped or use the appropriate syntax.
Can I convert secrets safely?
Yes, all conversion happens in your browser. However, be careful not to commit secrets to version control regardless of format.
What's the difference between .env and shell export?
Shell export format includes 'export ' prefix for direct use in shell scripts. .env format is just KEY=value without the export keyword.
Does this validate Kubernetes ConfigMap syntax?
The tool generates valid ConfigMap YAML structure. For full validation, use kubectl or a Kubernetes linter.
