I have a large excel file with a lot of data. I know how to delete the duplicate values but keep one value. I need to learn another technique. For example, a particular column repeats some data twice, some data thrice, and some data for four or five times. I want to delete the first entry only. I don't want to delete the second, third or fourth entry. That means only the first entry or first data will be deleted, but all the second, third, fourth or the next entry will exist. Will anybody please tell me how I can do this?
