Скачать или смотреть Data validation in MS Excel

Data validation is a useful feature in Microsoft Excel that helps ensure that data entered into a cell meets certain criteria. This can help prevent data entry errors and improve the accuracy and reliability of your data.


Here's how to use data validation in Microsoft Excel:


1. Select the cell or cells where you want to apply data validation.


2. Click on the "Data" tab in the ribbon at the top of the screen.


3. Click on the "Data Validation" button in the "Data Tools" group.


4. In the "Settings" tab of the "Data Validation" dialog box, choose the type of validation you want to apply. You can choose from a variety of options, such as whole numbers, decimals, dates, times, and text length.


5. Set the criteria for the validation. Depending on the type of validation you chose, you may need to set a minimum or maximum value, specify a range of values, or enter a specific value or formula.


6. Optionally, you can also customize the input message and error alert that users will see when they enter data that doesn't meet the validation criteria.


7. Click "OK" to apply the data validation.


Now, when users enter data into the cell or cells you've selected, Excel will automatically validate the data based on the criteria you've set, and display an error message if the data is not valid.
