.env to YAML Converter

Summary

This tool converts .env (dotenv) files to YAML entirely in your browser, no server upload required. Each KEY=value line becomes a YAML key, quoted values are unwrapped, and numbers, booleans, and null values are typed automatically. Comment lines and blank lines pass through unchanged so the output stays readable and easy to diff against the original file.

How it works

1. Paste the contents of your .env file into the input panel on the left.
2. Lines starting with # pass through as YAML comments; blank lines are kept as-is.
3. Each KEY=value pair becomes a YAML key, with surrounding quotes stripped from the value.
4. Numeric, boolean, and null-like values are converted to typed YAML; everything else stays a string.
5. The YAML output appears instantly in the panel on the right.
6. Click "Copy YAML" to copy the result to your clipboard.

Use cases

• Migrate a .env config into a YAML-based app config or Docker Compose environment block.
• Convert dotenv settings for Kubernetes ConfigMaps or Ansible variable files.
• Review environment variables in a more structured, typed format.
• Prepare a .env file for tools that only accept YAML input.
• Keep comments and grouping intact while switching config formats.
