A spreadsheet is a computer program organizing cells, containing numbers, dates, or text, into columns and rows. Then the values of these cells are used in formulas in other cells to give results. When a number is changed in one place, the results of other cells change immediately. This is extremely useful for business forecasting, bookkeeping, and so forth.
