Create data validation drop down list with build-in in Excel
Please do as follows to create a data validation drop-down list in Excel.
- Select where you will place the drop-down lists.
- Click "Data" > "Data Validation". See screenshot:

- In the popping up "Data Validation" dialog box, configure as follows:
- Under the "Settings" tab, select "List" from the "Allow" drop down list;
- In the "Source" box, select the source data to display in the drop-down list. Alternatively, values can be entered manually and separated by commas.
- It is optional to configure the fields under the "Input Message" tab and the "Error Alert" tab as shown in the following screenshots.


- After finishing all the settings, click "OK".

Now the drop-down list is created.
Notes:
- The drop-down arrow is visible only when the cell is selected.
- To enable automatic updates to your drop-down list, simply convert the source data into an Excel table. This ensures that any additions or deletions to the list are automatically reflected in the drop-down menu.
- If the data list hasn’t been converted to a table, but you still want the drop-down list to update automatically when adding or deleting items, you can enter the following dynamic formula directly into the "Source" box:
=OFFSET(Sheet2!$A$2,0,0,COUNTA(Sheet2!$A:$A),1)Here "Sheet2!$A$2" represents the first cell of the data list (excluding the header), and "Sheet2!$A:$A" indicates that the data list is located in column A of Sheet2. - If you have configure the "Error Alert" tab, an error alert will pop up with a specific title and error message when invalid data is entered into the drop-down list cell.
