Please Note: This article is written for users of the following Microsoft Excel versions: 2007, 2010, 2013, 2016, 2019, and Excel in Office 365. If you are using an earlier version (Excel 2003 or earlier), this tip may not work for you.

When you are developing worksheets that will be used by others, you may want to limit what your users can enter into a particular cell. For instance, you might have a cell where the user should enter their department. You would obviously want them to only enter one of the valid departments for your company.
To ensure that only certain departments can be entered in the cell, follow these steps:
Figure 1. The Settings tab of the Data Validation dialog box.
Figure 2. The Error Alert tab of the Data Validation dialog box.
That's it. Now, the user can only enter one of your valid department names. Better yet, when they select the cell, they will see a drop-down arrow at the right of the cell where they can select from the department names you specified in step 5. If they enter one that is incorrect, they will see the error message and will need to change what they entered.

Be aware that the Source box has a limit of 256 characters, otherwise you've got to use a range reference for the values.
More importantly, Data Validation only affects values that you type into a cell. If you Copy/Paste the values in, or use Find/Replace, the Validation has no effect.
