This is likely an easy feat for those how to work Sheets but I have no idea how to do it myself. I am looking at a quarterly report of airline complaints, where the source publishes one csv per quarter. These quarterly reports have the airline names in column A with the type of complaints in the subsequent columns, with a count for each type of complaint received per airline.
| Airline | Complaint type 1 | Complaint type 2 |
|---|---|---|
| Airline 1 | 23------------ | 12---------------- |
| Airline 2 | 21------------ | 7----------------- |
There are specific types of complaints that interest me and I would like to add up those quarterly reports to have the count of complaints for the year. The only issue is that the amount of airlines doesn't match between quarterly reports, so Q1 might show airlines 1-50 but others might be missing airlines 34-41, or might even have airlines 50-55 that don't show up on the Q1 sheet. I am after a function where I can ask to find the count of, say, complaint type 1, for each airline, in order to add up to a yearly total (in this case I have a tab for each quarter). Can anyone help with this?
