VLOOKUP is a powerful Excel function that allows you to look for a specified value in one column of data inside a table, and then fetch a value from another column in the same row.
Many users have heard of the Excel Vlookup function but are not clear about what it does. Vlookup (short for 'vertical' lookup) is a built-in Excel function that is designed to work with data that is organised into columns. For a specified value, the function finds (or 'looks up') the value in one column of data, and returns the corresponding value from another column.
