This is definitely a strange structure to parse - I also tried this endpoint / resource: https://api.worldoftanks.ru/wot/encyclopedia/vehicles/?application_id=demo - because the one you provided had a note about being deprecated and was hoping they would combine the structure. I am not sure why a single member is created to return a row of data for the same field names. If there isn't a way to adjust the response in the API with provided parameters AND all the field names that come back are the same, then Qlik should automatically concatenate this into one table. Let me know if you would like me to solicit additional help.
When applicable please mark the appropriate replies as CORRECT. This will help community members and Qlik Employees know which discussions have already been addressed and have a possible known solution. Please mark threads as HELPFUL if the provided solution is helpful to the problem, but does not necessarily solve the indicated problem. You can mark multiple threads as HELPFUL if you feel additional info is useful to others.
