Questions and answers

What is Env File Manager?
A .env file stores environment variables as KEY=value lines that dotenv libraries load at startup. This manager parses one, flags invalid keys, duplicates, empty values and unquoted spaces, lets you edit the variables, and converts to or from JSON, YAML, shell export and docker run --env flags.
Does Env File Manager store or send my data?
No. All processing happens entirely in your browser. Your environment variables stay on your device — nothing is sent to any server.
What .env formats does Env File Manager support?
It supports standard .env files, Docker env format, JSON, YAML, and Shell export syntax. You can convert freely between all of these formats.
