  • csv” for use when csv-data is generated
  • json” which formats proper json content (but without a field header)
  • jsonf” which formats as a complete json field
  • jsonr” which avoids double escaping the value but makes it safe for a json field
  • jsonfr” which is the combination of “jsonf” and “jsonr”.
