Copying new records from a large list

[cptawesome]

I have a spreadsheet that contains yearly data for entries into a contest. The entries are based on employees number, and maintains an updated count of entries.

I receive a new spreadsheet monthly, that updates totals for each employee. However, this new spreadsheet also contains new employees that aren't in the current list. Both lists are very large, so I would like to figure out a way to automatically update the totals for each employee, as well as automatically add new employees. Is there any way to do this?

To best describe or illustrate your problem you would be better off attaching a dummy workbook. The workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook.
