Access Import

I need to find a way to import from a spreadsheet records without getting duplicates. I have a program that has every truck visit closed within 3 months and I need to add just the new ones everyday. There is no way to only the most recent dates. So when I import it into my access database I get duplicates. I need the entire record that matches another entire record to be excluded from the import.
