VLOOKUP is a powerful reference function within Excel. If you need to lookup values in a table or range of cells to use somewhere else in your spreadsheet VLOOKUP may be just the ticket. In many cases this function can replace spreadsheet logic that utilizes nested IF functions. VLOOKUP can be in two ways, either as an exact match or approximate match. Typically when you are looking up numeric values approximate match is used, while for text lookups exact matches are most common.
