Now, you can also call this the copy-paste method. You can copy the cell that has data validation and paste it to another cell. The resulting cell will also have the data validation drop down in it.

Or you can use the fill handle to copy the data validation in multiple cells.

You can drag down the Fill handle icon to copy the data validation list in a particular column.

After that, you will see all the cells are having the data validation list in them. Now, click on the icon and select your data.

6. Error Handling in Data Validation

Let’s enter an item that is not on our list:

Now, press Enter . You will see the following message:

As our item was not on the list, it won’t take this as a valid item. This is an Error Alert in data validation. You can customize it in various ways.

In Microsoft Excel, you can show three types of error messages. These are Stop, Warning, and Information .

Select the Title and Error Message you want to show when a user gives an invalid input.

6.1 Stop Style

It will appear when the user gives an invalid entry. This option allows the user to retype or cancel the attempt.

The warning style shows a message that gives a user a choice to allow the item that is not in the list you selected.

7. Allow Entries That Are Not in Excel Drop Down List

When you add the data validation, an error alert is automatically turned on. That means you can not enter invalid items in the column. Now, you may be in a situation where you have to allow the user to enter items that are not selected in the list. In this situation you can follow two methods:

7.1 Turn Off Error Checking

To allow the entries that are not on the list, you can turn off the error checking option. By doing that, Excel won’t show any error message for other values and it will accept any item given by the user.

In the Data Validation dialog box, select the Error Alert タブ。 Then uncheck the option as we showed in the picture.

After that, you can enter any other values outside the list to in the Excel data validation list.

You can again select all the cells and create a data validation with the new list. It will also do the work. Now, there is another easy way to solve this.

📌 Steps

• First, select the first cell of the column.
• After that, go to the Data Then, from the Data Tools group, click on Data Validation . You will see a Data Validation dialog box.
