JSON to ENV Converter

Converting JSON Config Into Environment Variables

JSON is useful when configuration is structured, nested, and easy to read. But local development files, deployment dashboards, Docker setups, and CI/CD tools often expect simple dotenv variables instead of nested JSON objects.

This JSON to ENV Converter turns JSON object keys into clean .env variables while preserving the original values. You can flatten nested paths, quote values safely, format arrays, handle null values, and copy the generated environment variables into your project.

Creating .env Variables From JSON Without Rewriting Every Key

1. Paste valid JSON into the input box.
2. Select how values should be quoted.
3. Choose whether nested object keys should be flattened.
4. Select how arrays and null values should be handled.
5. Click Convert JSON to ENV and copy the formatted output.

Common JSON to ENV Converter Use Cases

• Turning JSON config files into local .env variables.
• Preparing API keys and service URLs for app setup.
• Flattening nested app settings before adding them to CI/CD tools.
• Generating dotenv values for Node.js, Next.js, Docker, and scripts.
• Creating .env.example files from structured JSON documentation.
• Cleaning exported dashboard settings before sharing setup steps.

Example JSON to ENV Conversion

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

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

Flattening Nested JSON Keys for Dotenv Files

Nested JSON is common in API responses and configuration exports. Dotenv files are usually flat. When nested key flattening is enabled, this tool turns paths like database.host, api.baseUrl, and auth.jwtSecret into DATABASE_HOST, API_BASE_URL, and AUTH_JWT_SECRET.

This keeps the generated variables readable without losing the meaning of the original JSON structure. It also makes the output easier to paste into hosting dashboards, shell scripts, and project documentation.

Quoting ENV Values Safely

Some environment values are safe without quotes, while others need quotes because they contain spaces, hash symbols, equal signs, line breaks, quotes, or special characters. Auto quote mode keeps simple values clean and quotes only values that are likely to need it.

You can also force every value to be quoted or leave every value unquoted. This is helpful when your project or deployment platform expects a specific dotenv style.
