Frequently Asked Questions

Quick answers for when your brain just wants the gist.

What is a .env file?

A .env file stores environment variables as simple KEY=VALUE pairs. It's commonly used to manage secrets and configuration in apps without hardcoding them into your codebase.

How do I convert .env to JSON?

Just paste your .env content into the input field and the tool will instantly generate structured JSON. No setup, no config, no drama.

Can I convert JSON back to .env?

Yup. It works both ways. Drop in your JSON and get a clean .env file ready to use in your project.

Is my data stored or sent anywhere?

Nope. Everything runs in your browser. Your data stays on your machine, exactly where it should be.

How are duplicate keys handled?

If the same key appears more than once, the last value takes priority. This mirrors how most systems handle environment variables in practice.

Can I create nested JSON from flat .env variables?

Yes. Use naming patterns like dots or underscores to group values. For example, APP_DB_HOST can become a nested JSON structure automatically.
