.env File Parser
Parse and inspect .env files. Convert environment variables to JSON, validate syntax, and identify secrets.
About .env Files
.env files store environment variables for applications. They keep sensitive config (API keys, database passwords) out of source code. Used with Node.js (dotenv), Python (python-dotenv), Docker, and virtually every modern framework. Never commit .env files to version control.
Frequently Asked Questions
What is a .env file?
A .env file is a plain text file containing key=value pairs for environment variables. It's used to configure applications without hardcoding settings, and to keep secrets like API keys out of your codebase. Always add .env to .gitignore.
Are my values sent to a server?
No. All parsing happens entirely in your browser using JavaScript. Your environment variables, API keys, and passwords never leave your device.
What syntax is supported?
This parser supports: KEY=value, KEY="quoted value", KEY='single quoted', inline comments (#), full-line comments, and empty lines. It follows the dotenv specification used by Node.js, Python, and Docker.
