How To Set Up Data Validation in Excel?
Good old Excel has several benefits. One of the researches from the 12th International Conference on Information and Education Technology 2024 stated that Excel is a highly trusted and user-friendly tool for data visualization, offering an intuitive interface, visually appealing graphics, and strong functionality that make it a preferred choice for students and professionals alike.
No wonder why it’s still so popular. One of Excel’s must-use tools nobody should forget though is the data validation option.
How to Set Up Data Validation in Excel
Time needed: 2 minutes
To set up validation for a cell or range of cells, follow these steps:
- Select the data
Select the cell or range of cells to which you want to apply this rule.
- Activate the Data Validation window
In the “Data” tab of the ribbon, click the “Data Validation” button.
- Set up data validation settings
In the “Data Validation” window, choose the type of validation that you want to set up. You can choose from a variety of options, such as “Whole Number,” “Decimal,” “Date,” or “List.”
- Additional settings
Set any additional options for this rule. For example, if you choose the “Whole Number” option, you can specify a minimum and maximum value for the cell.
- Save
Click “OK” to apply the rule to the selected cells.
Once you have set up validation for a cell or range of cells, Excel will enforce your defined constraints. If a user tries to enter data that does not meet the constraints, they will see an error message and will be unable to enter the invalid data.

Excel Data Validation Tools: Drop-down Lists
Excel’s data validation tools offer a powerful feature: the ability to create a drop-down list within a cell. This is especially useful when you need to restrict input to a predefined set of options, ensuring consistency and reducing errors.

Follow these steps:
- Select the cell or range of cells to which you want to apply the drop-down list.
- In the “Data” tab of the ribbon, click the “Data Validation” button.
- In the “Data Validation” window, choose the “List” option.
- In the “Source” field, enter the list of options that you want to include in the drop-down list. You can either type the list manually or you can select a range of cells that contain the list.
- Click “OK” to apply the rule to the selected cells.

Excel Data Validation Tools: Formula-based Rules
In addition to the built-in validation options in Excel, you can also use formulas to set up more complex rules. For example, you might want to set up a rule that allows a cell to contain a value only if it meets certain criteria.
How to Set Up a Formula-based Excel Validation Rule?
Follow these steps:
- Select the cell or range of cells to which you want to apply the validation rule.
- In the “Data” tab of the ribbon, click the “Data Validation” button.
- In the “Data Validation” window, choose the “Custom” option.
- In the “Formula” field, enter the formula that you want to use for the validation rule. The formula should return either “TRUE” if the data is valid or “FALSE” if the data is invalid.
- Click “OK” to apply the rule to the selected cells.
Using formulas for validation allows you to create very specific and customized rules for your data. For example, you might use a formula to ensure that a cell contains a number that is divisible by 10, or that a cell contains a date that falls within a certain range.
