What is .env File Viewer & Editor?

.env File Viewer & Editor parses, displays, and edits environment variable files with built-in secret masking. Environment files often contain sensitive data like API keys, database passwords, and tokens — this tool lets you inspect and modify them without ever sending that data to a server.

How to Use

  1. Paste your .env file content or load the sample data
  2. Click Parse to view variables in a structured table with masked values
  3. Click the eye icon to reveal individual values, or use Show All
  4. Edit values inline, add new variables, or export the modified .env file

Use Cases

  • Safely reviewing .env files without accidentally exposing secrets on screen
  • Comparing and editing environment configs across development, staging, and production
  • Validating .env files for duplicate keys or missing values before deployment
  • Onboarding new team members by providing a masked view of required environment variables

Privacy & Security

All processing happens entirely in your browser. Your environment variables, API keys, and passwords are never sent to any server. This is especially critical for .env files which contain the most sensitive configuration data in any project.
