To create a data validation drop-down list in Excel, use the Data Validation feature to restrict cell input to predefined values.

Method 1: Create a Drop-Down List by Typing Values Directly

This method suits short lists that rarely change.

Steps

1. Select the cell or range where the drop-down list is required.

2. Go to the Data tab on the ribbon.

3. Click Data Validation in the Data Tools group.

4. In the Settings tab, select List from the Allow field.

5. Enter the allowed values in the Source field, separated by commas.

6. Click OK.

The selected cell displays a drop-down arrow that limits input to the specified values.

Method 2: Create a Drop-Down List from Cells in a Worksheet

This method suits lists that need updates over time.

Steps

2. Select the target cell or range.

3. Open Data Validation from the Data tab.

4. Choose List in the Allow field.

5. Select the cell range containing the list items in the Source field.

Named ranges reduce errors and improve worksheet maintenance.

Method 4: Create a Dynamic Drop-Down List Using an Excel Table

This method ensures automatic expansion when new values are added.
