The Environment Variable Template Generator turns a plain list of key names — with or without example values — into a properly formatted .env.example file, the convention most teams use to document required environment variables without committing real secrets. Typing this out by hand across a growing project is easy to get inconsistent; this tool normalizes key casing and formatting so every teammate gets a clean, ready-to-copy template. It's handy when onboarding a new project, adding a new required config value, or documenting an API's environment setup for others.
How to use it
Enter one variable per line, either as just a key name (e.g. API_KEY) or as key=example-value (e.g. NODE_ENV=development). Click Copy or Download to get your .env.example file, then commit it alongside your project so collaborators know exactly which variables to set locally.
Frequently asked questions
Will this expose my real secret values?
No — you control exactly what's typed in. Use placeholder or example values rather than real secrets when generating a shareable .env.example.
Does it enforce a naming convention?
Keys are uppercased and spaces are converted to underscores, matching common .env conventions.
Can I download the file directly?
Yes, a Download button saves the output as .env.example.
