ENV File Parser Online
Parse .env files into a clean table, JSON, or export format
Paste your .env content above or drag-and-drop a file
Secrets are detected and masked automatically — your data never leaves your browser
About this tool
ENV File Parser Online is a free browser-based tool that parses .env files into a clean, readable table and lets you export the variables as JSON, shell export statements, or Docker --env flags. It handles quoted values, inline comments, multiline values, empty variables, and automatically detects secrets by key name — masking them by default so they are safe to share on screen.
Paste your .env content directly or drag-and-drop a file. All parsing happens in your browser — your environment variables are never sent to any server. This is especially important for .env files that contain API keys, database credentials, and JWT secrets.
Common use cases
- Quickly inspect all variables in a .env file as a clean table.
- Convert a .env file to JSON for use in configuration scripts.
- Generate shell export statements to source variables in a terminal session.
- Build Docker --env flags from a .env file for container runs.
- Audit a .env file for missing or empty required variables.
- Search across all keys and values to find a specific variable quickly.
- Share a .env file review with teammates without exposing secret values.
- Compare .env variables across environments (dev, staging, production).
Frequently Asked Questions
Is my .env file sent to a server?
No. All parsing happens locally in your browser using JavaScript. Your environment variables, API keys, and secrets never leave your device.
How does secret masking work?
Keys that contain words like "secret", "password", "token", "key", "api_key", "private", or "auth" are automatically identified as sensitive and their values are masked with dots in the table view. You can toggle masking on or off at any time.
Does it handle quoted values?
Yes. Both single and double quoted values are supported. Quotes are stripped from the parsed value. Multiline values wrapped in double quotes are also handled.
Does it support comments?
Yes. Lines starting with # are parsed as comments and shown as section headers in the table. Inline comments (e.g. KEY=value # comment) are also parsed and shown.
Can I upload a .env file directly?
Yes. Click Upload or drag and drop a .env file onto the input area. The file is read locally.
What export formats are available?
JSON object, shell export statements (export KEY="value"), and Docker --env flags for use with docker run commands.
