Download Quiz data when quiz items are Latex/Images

[dmis]

We use canvas quizzes for exams with question and choice order randomization. We want to export the student data for analysis, but most of the answer choices are embedded latex or images. Thus when we view the student report, the entry in the csv is blank and it does not appear that the student selected anything. Is there any way around this, to export student data in some format for offline analysis?

I tried editing the quiz after it was taken to add letters to each answer choice, but the student report did not change.

Thanks
