ENV Formatter brings environment variables to a consistent layout: sort keys, remove extra spaces around =, preserve comments and blank blocks, find duplicates, empty values, and invalid lines.
Useful for Node.js, Next.js, NestJS, Docker, backend services, CI/CD, and local development. Can also create .env.example with keys but no real values.
.env often contains secrets, so results with real tokens and passwords must not be committed to git.
