This article describes the formula syntax and usage of the VLOOKUP function
(function: A prewritten formula that takes a value or values, performs an
operation, and returns a value or values. Use functions to simplify and shorten
formulas on a worksheet, especially those that perform lengthy or complex
calculations.) in Microsoft Excel.

Description
You can use the VLOOKUP function to search the first column of a range (range: Two or more cells on a sheet. The cells in a range can be adjacent or nonadjacent.) of cells, and then return a value from any cell on the same row of the range. For example, suppose that you have a list of employees contained in the range A2:C10. The employees' ID numbers are stored in the first column of the range, as shown in the following illustration.
