When we export the results for the surveys “André”, “João” and “Marcos” the .xls file is corrupted and we can only export them in .csv format.
Is there anything wrong with our reports on these surveys?
Typically when you have special characters such as the ones you have mentioned, the xls version is the one that you will need to use.
If there is an issue with your xls file, you may need to reach out to SurveyGizmo directly (if you have not already), and see if they can determine what the problem might be.
Hope this helps!
