Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.
