How data validation works in Microsoft Excel
Certainly! Data validation in Excel is a powerful feature that allows you to control the type of data entered into a cell. By setting rules, you can maintain accuracy and consistency in your spreadsheets. Here’s how it works:

1. Select the cell(s) where you want to apply data validation.
2. Go to the Data tab and click on Data Validation.
3. On the Settings tab, choose an option under Allow:
– Whole Number: Restricts the cell to accept only whole numbers.
– Decimal: Restricts the cell to accept only decimal numbers.
– List: Allows you to pick data from a dropdown list.
– Date: Restricts the cell to accept only dates.
– Time: Restricts the cell to accept only time values.
– Text Length: Limits the length of text entered.
– Custom: Use your own formula for validation.

4. Under Data, select a condition (e.g., greater than, less than, between).
5. Customise an Input Message that users will see when entering data (optional).
6. Set up an Error Alert:
– Stop: Stops users from entering invalid data (requires them to retry).
– Warning: Warns users but allows them to proceed after dismissing the warning message.
– Information: Displays a custom message but doesn’t prevent input.

Remember that while data validation helps guide users, it’s not fool proof. Users can still bypass it by copying data from cells without validation. However, it’s a valuable tool for maintaining data quality and consistency in your Excel workbooks .Microsoft Excel tutorial
