NewBuild .env and .env.example files from common presets or custom key-value pairs.

Rows
Secret rows keep their real value in .env and use a placeholder in .env.example.
Frequently Asked Questions
What changes when I mark a row as Secret?
The real value stays in the generated .env file, but the .env.example file gets a placeholder like your_jwt_secret_here instead of the real secret.
Do the preset buttons know which keys are probably secrets?
Yes, in a simple way. Preset-added keys matching SECRET, PASSWORD, KEY, or TOKEN are auto-marked as secret when the rows are inserted.
Why are normal values blank in .env.example?
That is how this generator is written. Non-secret rows become KEY= with an empty example value, while only secret rows get explicit placeholders.
Will it quote values with spaces or # characters?
Yes. Values are left plain by default, but anything containing whitespace, #, or a double quote is JSON-quoted before being written.
Can this generate comments, export statements, or variable interpolation?
No. It only emits straightforward key=value lines for .env and .env.example.
