Are my environment variables sent to a server?

No. All parsing and conversion happens locally in your browser using JavaScript. Nothing is transmitted to any server.

Are comments preserved in the output?

Yes. Lines starting with # pass through unchanged, since # is a valid comment marker in both dotenv and YAML. Blank lines are also kept to preserve the original grouping.

How are quoted values handled?

Values wrapped in single or double quotes have the quotes stripped, then the resulting string is re-typed for YAML: quoted only if it contains special characters, otherwise left plain.

How are numbers and booleans handled?

Purely numeric values are emitted as YAML numbers. Values of true, false, yes, no (case-insensitive) become YAML booleans, and empty or null-like values become YAML null.

What happens with duplicate keys?

If the same key appears more than once, the last occurrence wins, matching how most dotenv parsers behave.

Can I convert YAML back to .env format?

This tool converts one direction: .env to YAML. For the reverse, use a YAML to .env converter, or the YAML to INI converter for a similar flat key-value format.

Summary

Paste a .env file and convert it to clean YAML config, with comments and blank lines kept in place.

How it works

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