Excel allows you to create spreadsheets much like old paper ledgers that can perform automatic calculations. Each Excel file is a workbook that can hold many worksheets. The worksheet is a grid of columns (designated by letters) and rows (designated by numbers). The letters and numbers of the columns and rows (called labels) are displayed in gray buttons across the top and left side of the worksheet. The intersection of a column and a row is called a cell. Each cell on the spreadsheet has a cell address that is the column letter and the row number. Cells can contain text, numbers, or mathematical formulas.

To add a sheet, select Insert Worksheet tab just to the right of the existing tabs. To rename the worksheet tab, right-click on the tab with the mouse and select Rename from the shortcut menu. Type the new name and press <Enter> .
