One of the tools provided with Excel allows you to ensure that the data in your workbook is within specific bounds, and therefore of a higher quality than unchecked data. This tool is referred to as data validation, and it allows you to set the bounds applicable to your data.
For example, lets assume you are creating a simple worksheet to calculate the future value of a sum, and that in order to do so, you need input from the user (regular deposit, interest rate, and months). You may want to place limits on the information which can be used in the worksheet. For example, you may want to make sure the user always enters an interest rate between 2.5% and 25%. Follow these steps:
Figure 1. The Data Validation dialog box.
Effectively, you have set a validation rule that says "accept any decimal value that is between 2.5% and 25%." If the user tries to add information to the cell that is outside the range you specified, they are notified that they have made an error and a different value must be entered.
