.env file parser: what it is for
Paste the contents of a .env file and see the variables organized, with keys, tokens and passwords hidden until you choose to show them. The tool flags repeated variables, invalid names, empty values, unclosed quotes and spaces around the equals sign, and converts everything to JSON, YAML, docker run -e parameters or shell export lines.
Everything runs in your browser: nothing you paste or open is sent to a server.
How to use
- Paste the .env content.
- See the table and warnings.
- Choose the format and copy.

- Review settings before deploying.
- Pass variables to Docker.

Frequently asked questions
What problems does it point out?

How does it know what is a secret?
By the name: variables containing KEY, SECRET, TOKEN, PASSWORD, PASS, PRIVATE or CREDENTIAL stay hidden in the table until you click show.
