What .env file formats are supported?

The parser supports standard .env syntax: KEY=VALUE pairs, comments starting with #, empty lines, single-quoted and double-quoted values, and inline comments after unquoted values. Double-quoted values support escape sequences like \n and \t.

What output formats are available?

You can convert to four formats: JSON (as a key-value object), YAML, Docker --env flags (for use with docker run), and shell export commands (for sourcing in bash/zsh).

Does this handle multiline values?

Yes. Values enclosed in double quotes or single quotes can span multiple lines. The parser will correctly capture everything between the opening and closing quotes.

Is my .env data sent to a server?

No. All parsing and conversion happens entirely in your browser. Your environment variables never leave your device. This is especially important since .env files often contain secrets and API keys.

How are special characters handled?

In double-quoted values, escape sequences like \n (newline), \t (tab), and \" (escaped quote) are processed. Single-quoted values are treated as literals with no escape processing. Unquoted values are trimmed and inline comments are stripped.

Working with .env Files

The .env file is a standard way to store environment variables for application configuration. It keeps sensitive data like API keys, database URLs, and feature flags separate from your codebase. Libraries like dotenv (Node.js), python-dotenv, and godotenv load these files automatically.

This tool helps you convert between formats when migrating configurations. For example, convert a .env file to Docker --env flags for container deployment, to YAML for Kubernetes ConfigMaps, to JSON for programmatic use, or to shell exports for CI/CD scripts.
