I have a csv file with 3 fields- state code, county code, and city code. I want to create an interface that will prompt me to select one of those 3 so as to drive the excel spreadsheets. Ex- if county is selected, I want each county code to have its own sheet. If city is selected, i want each city code to have its own sheet. For the purpose of this project, there will never be more than one state. If state is selected, all data should be put into a single sheet.
