.env Parser
Parse .env files into JSON, YAML, shell exports, or back to .env. Edit values in a table. 100% client-side — your secrets stay local.
🔒 Privacy: Your .env file is parsed locally in your browser. Nothing is uploaded. Still, best practice: use
.env.example for sharing, never real secrets.10

About .env Parser
.env files are the standard way to store environment variables for applications — API keys, database URLs, feature flags, and other configuration. They are used by Node.js (dotenv), Python (python-dotenv), Ruby, Docker Compose, and many CI/CD systems. Yet .env files are simple text without a formal spec, which makes debugging tricky: quotes, escapes, comments, and shell expansion all behave in subtle ways. This tool parses any .env file into a clean table, shows each variable with its value and comment, detects quoting style, and converts to JSON, YAML, or shell exports. Because secrets are often stored in .env files, this tool runs entirely in your browser — nothing is uploaded.
How It Works
- Paste or upload a .env file.
- See each variable parsed into a table (key, value, quote style, comment).
- Edit values, add new variables, or remove existing ones.
- Export as JSON, YAML, shell exports, or back to .env format.
✨ Key Features
- ✓Parse .env files with full syntax support
- ✓Handle single quotes, double quotes, and unquoted values
- ✓Handle escape sequences (\n, \t, \", \\)
- ✓Skip and preserve comments (# ...)
- ✓Handle multi-line values with quotes
- ✓Detect shell-style expansion ($VAR, ${VAR})
- ✓Editable table view
- ✓Add / remove variables
- ✓Hide secret values (mask view)
- ✓Export to JSON
- ✓Export to YAML
- ✓Export to shell export statements
- ✓Export back to .env format
- ✓100% client-side — your secrets never leave your browser
🎯 Common Use Cases
- →Debugging a .env file that is not loading correctly
- →Converting .env to JSON for a Node.js config
- →Preparing .env for Docker Compose or CI/CD
- →Documenting environment variables for a project
- →Migrating config between platforms
- →Reviewing .env files safely without exposing secrets
- →Generating shell export statements for scripting
- →Converting to YAML for Kubernetes ConfigMaps
💡 Advanced Tips & Pro Insights
- ▸Double quotes ("...") interpret escapes (\n, \t) and expand variables ($VAR). Single quotes ('...') preserve everything literally. Unquoted values are trimmed of whitespace but do not support escapes.
- ▸Values with spaces MUST be quoted in .env. Otherwise, the parser stops at the first space.
- ▸Comments start with #. They can be on their own line or after a value (only if separated by whitespace).
- ▸Variable expansion ($VAR, ${VAR}) is a shell feature — some .env parsers support it, others do not. This tool detects and preserves the syntax.
- ▸Never commit real .env files with secrets to git. Use .env.example with placeholder values, and add .env to .gitignore.
Frequently Asked Questions
Is this .env parser free?▾
Yes, this .env parser is completely free with no signup, email, or usage limits.
Is it safe to paste real .env files with secrets?▾
Yes — this tool is 100% client-side. Your .env content never leaves your browser. There is no upload, no server, no logging. However, as a general best practice, avoid pasting production secrets into any online tool unless you control the environment.
What is a .env file?▾
A .env file is a plain-text file that stores environment variables as KEY=value pairs. It is used by dotenv libraries (Node.js, Python, Ruby) and by Docker Compose to configure applications without hard-coding secrets.
What is the difference between single and double quotes?▾
Single quotes ('...') preserve everything literally. Double quotes ("...") interpret escape sequences (\n, \t, \") and expand shell variables ($VAR). Unquoted values are trimmed but do not support escapes.
Does it support multi-line values?▾
Yes. Multi-line values must be enclosed in quotes. Both single-quoted and double-quoted multi-line values are supported.
How are comments handled?▾
Lines starting with # are treated as comments and preserved. Inline comments (after values) are also detected and shown separately. Comments are included when exporting back to .env format.
Does it support variable expansion?▾
The parser preserves shell-style references ($VAR, ${VAR}) without expanding them. Actual expansion depends on the runtime that loads the .env file — some libraries support it, others do not.
Can I convert .env to YAML for Kubernetes?▾
Yes. Use the "Export YAML" option. The output is a valid YAML mapping suitable for Kubernetes ConfigMaps and Secrets (though for real secrets, use Kubernetes Secret resources).
