In Excel, you can create a drop down Data Validation list, so it’s easy to enter valid items in a cell.
Usually, the list of valid items is stored in the same workbook, but it’s possible to set up a drop down from a list in another workbook — as long as the other workbook is open.
The instructions are below, and watch the video to see the steps. The demo uses Excel 2010, and it’s the same in Excel 2007, except that there is an Office button, instead of a File tab.
Drop Down from a List in Another Workbook
Important Note: For the data validation to work, the workbook that contains the list must be open, in the same instance of Excel. Users will have to open both the workbooks — the one with the drop down lists, and the workbook with the original source list.
The following instructions are for Excel 2007 and later. On my website, there are similar instructions to create a data validation list from a different workbook in Excel 2003.

Create the Source List
In this example, you have a workbook named DataValWb.xlsx, which contains a list of customer names. This list is in a range named CustName. (For instructions on creating a named range, refer to Naming Ranges.)
Create a Named Reference to the Source List
Next, you’ll create named range in the workbook where the drop down list will be added.
- Open the workbook that contains the source list — DataValWb.xlsx in this example.
- Open the workbook in which you wish to use the list in Data Validation, or create a new workbook.
- On the Ribbon, click the Formulas tab, then click Define Name.
- Type a name for the List, e.g. MyCustList
- From the Scope drop down, select Workbook
- Click in the Refers to box — this is where you’ll type a reference to the named range in the source workbook
- Type an equal sign, then the source workbook name and extension. Do NOT include any square brackets in the name. For example:
=DataValWb.xlsx - OR, if the workbook name includes spaces, start and end the name with an apostrophe. For example: ‘DataVal May10.xlsx’
- Next, type an exclamation mark — !
- Finally, type the range name in the source workbook
- The completed reference should look like this:
=DataValWb.xlsx!CustName
OR =’DataVal May10.xlsx’!CustName
- Click OK

Create the Dropdown List
- Select the cells in which data validation will be set.
- On the Ribbon, click the Data tab, then click Data Validation
- In the Allow box, choose List
- In the Source box, type an equal sign, then the list name that you just created, e.g.: =MyCustList
- Click OK

Use the Data Validation List
Remember, to use the data validation drop down list, both workbooks must be open.
- Open both workbooks — the one with the drop down lists, and the workbook with the original source list.
- Select an item from the data validation drop down list.
Watch the Video
Watch this video to see the steps for creating a drop down from a list in another workbook. You’ll see how to set up the named ranges, and the drop down lists. The demo is in Excel 2010.

Brilliant. Gives me the solution to accessing data from a table on another sheet in the workbook. I was trying to refer to the cells address. Now I know just to name the group it’s so much easier. The fact that tha data was in a table confused me.
Works great, but one more bit of advice needed please. I have a folder set with data linked between workbooks, but when I move the folder to another location, the validation stops working. When I look at the ‘refers to’ in the name manager of the destination file, the path refers to the original loaction of the folder set.
How do I stop this unwanted renaming of the source data.
Hi – I have tried using the instructions to pull down a drop down validation list in one workbook using data source from another workbook. Have them both open and used same file names as in example but still get error saying I can’t use data from an external source. I don’t quite understand though, how excel can ‘find’ the data source from just the range, i.e. =MyCustList in source of data validation on one workbook and expect to find it with no other information from another workbook.
Thanks! This is very useful!
Roy, I’m hoping someone answered you, or that you figured it out. I have the same issue and would like to hear about a solution.
@Roy and @Les, if you open the source workbook first, and then the workbook with the drop down lists, does it update the links correctly?
