Answer

To edit a drop-down list in Excel, change the source used by Data Validation or modify the named range or table that feeds the list.

Identify How the Drop-Down List Was Created

A drop-down list is created using Data Validation. The source comes from one of three structures.

1. A manually typed list.

2. A cell range.

3. A named range or table.

Edit a Drop-Down List Created from a Manually Typed List

A manually typed list stores values directly inside Data Validation.

1. Select the cell that contains the drop-down list.

2. Open the Data tab.

3. Select Data Validation.

4. Select Data Validation again.

5. Locate the Source field.

6. Edit the values separated by commas.

7. Select OK.

Each value is treated as a text entry. Order changes reflect immediately in the drop-down list.

Edit a Drop-Down List Created from a Cell Range

A range-based list pulls values from worksheet cells.

1. Locate the cells that supply the list.

2. Edit, add, or delete values directly in those cells.

3. Select the drop-down cell.

4. Open Data Validation.

5. Confirm the Source range reflects the correct cells.

6. Select OK.

Blank cells inside the range appear as empty options. Remove blanks to keep the list clean.

Edit a Drop-Down List Created from a Named Range

A named range centralizes control of the list.

1. Open the Formulas tab.

2. Select Name Manager.

3. Select the named range used by the list.

4. Select Edit.

5. Adjust the referenced cells.

6. Select OK.

Changes apply across every drop-down that references the same name.

Edit a Drop-Down List Created from a Table

Tables expand automatically when new values are added.

1. Locate the table feeding the list.

2. Add or remove entries within the table column.

3. Confirm the Data Validation source references the table column.

Tables maintain list integrity and prevent broken references.

Change the Source of an Existing Drop-Down List

A source change redirects the drop-down to new values.

1. Select the drop-down cell.

2. Open Data Validation.

3. Replace the Source with a new range, name, or typed list.

4. Select OK.

Existing selections remain valid only when they exist in the new source.

Remove Items from a Drop-Down List

Removing items depends on the source type.

1. Delete the value from the source range or table.

2. Remove the value from the Source field for typed lists.

3. Save the Data Validation settings.

Cells that previously used removed values retain the text until changed.

Edit Drop-Down Lists on Windows vs Mac

The core steps remain consistent across platforms. Interface access differs.

• Windows

  1. Data Validation opens from Data → Data Validation.

  2. Name Manager opens from Formulas → Name Manager.

• Mac

  1. Data Validation opens from Data → Data Validation.

  2. Name Manager opens from Formulas → Define Name.

Keyboard shortcuts differ by system settings, though functionality remains unchanged.

Common Issues When Editing Drop-Down Lists

Incorrect behavior results from source errors.

1. Extra spaces cause duplicate-looking entries.

2. Blank cells create empty options.

3. Mismatched ranges break validation.

4. Protected sheets block edits.

Fixing the source restores normal behavior immediately.

Best Practices for Editing Drop-Down Lists

Structured sources improve accuracy and scalability.

1. Use tables for dynamic lists.

2. Use named ranges for shared lists.

3. Avoid manual lists for large datasets.

4. Keep sources on a dedicated worksheet.

5. Validate changes by testing multiple cells.

These practices reduce maintenance and prevent data entry errors.
