## Overview

The .env Parser extracts and validates KEY=VALUE configurations from .env files. It detects duplicate keys, suspicious spaces, and quotes, and can export to formats like JSON, YAML, or JavaScript objects for easy integration.

## Inputs

- **.env File Content** (textarea): Paste your .env file content here...
- **Export Format** (select)
- **Validate Key Names** (checkbox)
- **Detect Variable Expansion** (checkbox)
- **Check for Security Issues** (checkbox)

## When to use

- When parsing .env files to ensure correct formatting and avoid runtime errors in applications.
- To validate environment variables for duplicate keys or security issues before deployment.
- When converting .env content to other formats like JSON or YAML for use in different systems.

## How it works

- Paste your .env file content into the input field.
- Select the desired export format, such as JSON, YAML, dotenv, or JavaScript Object.
- Enable validation options like key name checking, variable expansion detection, and security scans.
- The tool parses the content and outputs structured data with any detected issues highlighted.

## Use cases

- Validating .env files for Node.js or Python applications to prevent configuration errors.
- Converting .env variables to JSON for use in frontend JavaScript or backend services.
- Auditing .env files for security risks like exposed secrets or improper formatting before production.

## Frequently asked questions

### What export formats are supported?

The tool supports JSON, YAML, dotenv, and JavaScript Object formats.

### How does it detect security issues?

It checks for suspicious spaces, quotes, and other common vulnerabilities in .env files.

### Can it handle variable expansion?

Yes, it detects and validates variable expansion patterns like ${VAR} in .env files.

### What happens if duplicate keys are found?

The tool flags duplicate keys in the validation output to help resolve conflicts.

### Is my .env content stored or shared?

No, the tool processes content locally in your browser and does not store or transmit data.
