The downloaded JSON will look similar to the code below:

{
  "type": "service_account",
  "project_id": "id",
  "private_key_id": "key_id",
  "private_key": "-----BEGIN PRIVATE KEY-----\key\n-----END PRIVATE KEY-----\n",
  "client_email": "service account email",
  "client_id": "client id",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/etl-framework%40service-account@email"
