ENV to JSON Converter

Converting ENV Variables Into Structured JSON

Environment files are useful for local configuration, deployment settings, service credentials, API keys, feature flags, and runtime values. But when you need to review, document, transform, or move those settings into a structured config file, JSON is often easier to read and work with.

This ENV to JSON Converter parses dotenv-style key-value pairs and turns them into clean JSON. You can keep keys flat or nest underscore separated names, making it useful for debugging app configuration, preparing documentation, converting deployment settings, and reviewing environment files in a more structured format.

Creating JSON From .env Files Without Manual Editing

1. Paste valid .env content into the input box.
2. Select whether values should be parsed automatically or kept as strings.
3. Choose whether underscore-separated ENV keys should become nested JSON.
4. Select the spacing style for the generated JSON output.
5. Click Convert ENV to JSON and copy the formatted output.

Common ENV to JSON Converter Use Cases

• Turning .env files into structured JSON configuration.
• Reviewing deployment environment variables in a readable format.
• Converting dotenv values before sharing app setup documentation.
• Preparing JSON config from Node.js, Next.js, Docker, or CI/CD variables.
• Checking API keys, service URLs, feature flags, and runtime settings together.
• Cleaning shell-style export lines before moving values into JSON.

Example Before and After

Before:
DATABASE_HOST=localhost
DATABASE_PORT=5432
API_KEY=secret-key

After:
{
  "database": {
    "host": "localhost",
    "port": 5432
  },
  "api": {
    "key": "secret-key"
  }
}

Nesting ENV Keys Into JSON Objects

Many environment variables use prefixes to show grouping, such as DATABASE_HOST, DATABASE_PORT, API_BASE_URL, or USER_ACTIVE. Nested mode converts those underscore-separated names into JSON objects so related values sit together.

Flat mode keeps the original ENV keys exactly as top-level JSON properties. This is useful when you want a direct key-value export without changing names or grouping values.
