Setting Data Validation Rules - Data Validation in Excel

Data validation is the process of ensuring that data entered into a system complies with certain standards and rules. In Excel, data validation rules can be set to limit the data entered into a cell. In this tutorial, we will explore how to set data validation rules in Excel.

Getting Started with Setting Data Validation Rules

Syntax:

To set a data validation rule in Excel, follow these steps:

1. Select the cell or range of cells where you want to apply the validation rule.
2. Go to the "Data" tab in the Excel ribbon menu.
3. Click on "Data Validation" in the "Data Tools" group.
4. In the "Data Validation" dialog box, choose the validation criteria and enter the relevant values and/or formulas.
5. Click "OK" to apply the validation rule to the selected cell or range.

Example:

Let's assume that we want to set a validation rule that allows only whole numbers between 1 and 100 in the selected cell range. Here are the steps to set the validation rule:
