- Input Your .env Content — Paste your environment variables into the text area, or click 'Upload .env' to load a file from your computer. The parser handles quoted values, inline comments, and standard .env syntax.
- Parse — Click 'Parse' to convert the raw text into an editable table. Each variable appears as a row with Key, Value, and Comment columns.
- Edit Variables — Click any key, value, or comment field to edit it directly in the table. Duplicate keys are highlighted in red with a warning. Empty keys are also flagged.
- Manage Variables — Use '+ Add Variable' to create new entries. Click '✕' to delete individual variables. Use 'Sort A-Z' to alphabetize. Use the search bar to filter by key or value name.
- Security — Click the eye icon (👁️) to toggle masking of sensitive keys (any key containing SECRET, PASSWORD, TOKEN, KEY, API, or PRIVATE). Values are hidden with dots when masked.
- Export — Copy as .env format, copy as JSON object, or download as a .env file. All formats are generated cleanly from your current variable list.
Environment Variable Editor — Parse, Edit, and Export .env Files
The Environment Variable Editor is a free, secure tool for managing environment variables. Parse existing .env files into a visual table, edit keys and values inline, validate for duplicates and empty keys, mask sensitive values, search and sort, and export in .env or JSON format — all in your browser.
Environment variables are critical for application configuration, storing database credentials, API keys, and feature flags. This tool makes managing them safe and easy without risking exposure to external services.
Key Features
- .env Parser — Handles standard .env syntax including quoted values (double and single), inline comments (# notation), and multiline entries. Empty lines and comment-only lines are skipped.
- Visual Table Editor — Each variable is displayed in a clean table row with editable Key, Value, and Comment columns. Click any field to edit directly.
- Validation — Duplicate keys are highlighted in red with a warning badge. Empty keys are also flagged. This prevents common .env bugs that cause hard-to-debug issues.
- Sensitive Key Masking — Toggle the eye icon to mask values of sensitive keys (containing SECRET, PASSWORD, TOKEN, KEY, API, or PRIVATE). Values appear as dots, preventing shoulder surfing.
- File Upload — Upload .env files directly from your file system. Supports .env, .env.local, .env.production, and .txt files.
- Search & Filter — Type in the search bar to instantly filter variables by key or value. Useful for large .env files with dozens of variables.
- Sort A-Z — Alphabetically sort all variables by key name for organized, consistent .env files.
- Add / Delete — Add new variables with one click. Delete any variable with the ✕ button.
- Copy .env — Export the current variables in standard .env format (KEY=value) to clipboard.
- Copy JSON — Export as a JSON object for JavaScript/TypeScript configuration files.
- Download .env — Download the variables as a .env file directly.
Common Use Cases
- DevOps — Manage deployment environment variables for staging, production, and development environments.
- Local Development — Edit .env.local files for React, Next.js, Vue, Laravel, Django, Rails, and other framework projects.
- CI/CD — Prepare environment variables for GitHub Actions, GitLab CI, Vercel, Netlify, or Heroku deployments.
- Docker — Edit docker-compose .env files for containerized applications.
- Team Collaboration — Review and organize shared .env.example files before committing to version control.
- Security Audit — Quickly scan for sensitive keys and verify that no secrets are accidentally exposed.
Privacy & Security
The Environment Variable Editor processes all data entirely in your browser using JavaScript. No .env content is transmitted over the network. No data is stored on any server. The tool works completely offline once loaded. This makes it safe for handling production API keys, database passwords, and other sensitive configuration.
