About the ENV File Editor
The .env file is a foundational part of modern application development. Used by frameworks like Node.js (dotenv), Python (python-dotenv), Ruby (dotenv gem), and many others, it stores environment-specific configuration as simple key-value pairs. This tool helps you work with .env files more effectively.
Paste your .env content, and the parser handles comments, quoted values (single and double quotes), inline comments, and blank lines. The validator catches common mistakes before they cause runtime errors in production.
Features
Parse .env files with full support for comments, quotes, and multiline values
Visual table editor — edit keys and values inline, add or remove rows
What is a .env file and why do developers use it?▼
A .env file stores environment variables as key-value pairs (e.g., DATABASE_URL=postgres://...). Developers use .env files to keep configuration separate from code, manage secrets like API keys, and switch between development, staging, and production settings without changing source code. Libraries like dotenv load these files automatically.
Is it safe to paste my .env file into this tool?▼
Yes. This tool runs 100% in your browser using JavaScript. Your environment variables never leave your computer and nothing is sent to any server. However, you should always be cautious with production secrets — consider using dummy values when testing tools online.
What formats can this tool convert .env files to?▼
This tool converts .env files to six formats: standard .env (dotenv), JSON object, YAML, Docker Compose environment section, Shell export statements (bash/zsh), and Windows SET commands. Each format preserves your variable names and values with proper escaping.
How does the validation feature detect issues in .env files?▼
The validator checks for duplicate key names, empty or missing values, keys with invalid characters (env keys should be uppercase letters, numbers, and underscores), values that contain spaces but are missing quotes, and lines that don't follow the KEY=VALUE format. Each issue is flagged with a warning so you can fix it before deploying.
