Question about updating records using excel files

Hi is it possible to update the data in zoho reports using excel files. Let's say that I have product A's quantity in zoho reports as 5, then I upload an excel file that updates product A's record into 6 based on what is in the excel file. What I want to happen is when I upload an excel file, zoho reports only updates records that are different from its data. Is this easily done?
