About Dotenv Example Generator
The Dotenv Example Generator converts a real .env file into the .env.example template you commit to version control.
It keeps every variable name so teammates know exactly which settings the project needs, while stripping out the actual values so no API keys, passwords or tokens ever leak into your repository or its history.
Paste the contents of your .env and the tool rebuilds each line as KEY= with the value removed, replacing it with an empty placeholder by default or with any hint you choose, such as "changeme" or "<your-key-here>".
Comments and blank lines are preserved by default so the structure and documentation of your config survive the transformation, but you can switch that off for a bare list of keys.
Variable names are validated against the standard shell-safe pattern, and malformed lines — one missing an equals sign, or a name that starts with a digit — surface a clear, specific error instead of producing a broken file.
Because every byte is processed locally in your browser, your secrets are never uploaded anywhere, and the tool keeps working offline.
It is a fast, safe way to keep your example file in sync without manually retyping a single key.
FAQ
Are my secret values uploaded anywhere?
No. The conversion happens entirely in your browser. Nothing is sent to a server, so your real values never leave your machine.
Does it keep comments and section headers?
Yes, by default. Comment lines and blank lines are preserved so your example file stays readable; you can turn this off for a plain list of keys.
