.env to JSON Converter

Convert .env files to JSON and JSON back to .env — handles quotes, comments, export and nested keys.

How do I convert a .env file to JSON?

Paste a .env file and get a JSON object of all KEY=value pairs — quotes, escaped characters, export prefixes and # comments are handled, and you can turn true/false and numbers into JSON types. Paste JSON instead and nested keys are flattened into UPPER_SNAKE_CASE .env lines.

When you need it

Moving settings between Docker, Node.js (dotenv), Laravel, Vercel, Netlify or AWS.
Creating JSON config for CI pipelines or secret managers.
Turning a JSON config into environment variables.

Keep secrets safe

The conversion runs entirely in your browser, but never commit .env files with real passwords or API keys to Git — add .env to .gitignore.
