Although you can use a spreadsheet to set up tables of just textual information, its real usefulness lies in its ability to calculate formulas - and recalculate them automatically when values change.
Spreadsheets are great for budgets, financial statements and other tasks that require calculations.
Then, if the value in cell B2 or C3 changes, the value in the cell with the formula also changes. Many spreadsheet programs include predefined formulas for myriad financial calculations. Use spreadsheets to list and maintain groups of numerically based data. You can enter and edit data on several worksheets within a single document and perform calculations based on data from multiple worksheets. For example, you could have separate worksheets for each department's budget in a company, plus a worksheet for the whole company budget.
