JSON to .env Converter

Convert any nested JSON object into a ready-to-use .env file. Keys are uppercased and separators are replaced with underscores. Double quotes, backslashes, and newlines inside values are properly escaped for valid dotenv format.

Use Cases

  • Node.js Applications — Generate process.env configuration from JSON settings
  • Docker Compose — Create env_file content from structured config
  • CI/CD Pipelines — Convert build configuration into environment variables
  • Development Workflow — Quickly switch between JSON config and dotenv format

Example

Input:

{
  "database": {
    "host": "localhost",
    "port": 5432
  }
}

Output:

DATABASE_HOST="localhost"
DATABASE_PORT="5432"
