I have surveys in different languages and use to combine the results into the English version. This works perfectly but…is there a way to obtain not a report but individual responses for the combined report? (in English)
I am assuming that you are using the Combined Reporting feature described here:
The combined report feature can only be used with the Standard Report. It sounds like you want to view all Individual Responses combined? would this be via Results > Individual Responses?
Perhaps you could use the Data Import tool to export data from one survey and import it into another? Here is some information on the Data Import tool, in case you want to explore it:
Hope this helps!
