JSON to .env

Convert nested JSON objects into flat .env file format with proper key naming. Useful for converting config JSON to environment variables.

JSON Input (nested objects supported)

{
  "app": {
    "name": "myapp",
    "port": 3000,
    "debug": true
  },
  "database": {
    "host": "localhost",
    "port": 5432,
    "credentials": {
      "user": "admin",
      "password": "secret123"
    }
  },
  "features": ["auth", "api", "webhooks"]
}

Prefix

Separator

Nested objects flattened with separator. Arrays joined with commas. Values with spaces/special chars quoted. Booleans → "true"/"false". Null/undefined → empty.
