Microsoft Excel is a widely used spreadsheet software distributed as a part of the Microsoft Office package. Excel organizes data in the form of worksheets (spreadsheets), allowing a user to make various calculations on data as well as plot graphs. Each spreadsheet consists of cells identified with a letter/number combination; for instance, “A5” or “E12.” Excel built-in mathematical and other functions permit easy work with a cell range without typing each cell in this range explicitly.
