Each month I download a bill. Currently, I have seven months of billing information in excel spreadsheets that must be worked. It is getting a bit much to constantly go back to these individual speadsheets to review for changes which will result in credits back to us. I think I can manage them better if they were in one database. And, I will need to update this database monthly w/ the new info that I will download.
I have developed a sample database based on 1 month’s information. (see attached snap shot of database). My question is how best to go about appending additional information each month to this database? (attached is sample data for May, June and July).
