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.
________________________________

@Barbara, the connection to the other workbook is in the definition for the MyCustList named range that you create in the second workbook.
Here is the definition for MyCustList — it points to the CustName named range in the DataValWb file.
=DataValWb.xlsx!CustName
Thanks for the information provided here – it was very useful in the office. However, I have a difficult situation here that you may know something about (I’m taking the risk regardless!).
I have an Excel template that my colleagues will use to produce other spreadsheets. It has several drop down menus that connect to a separate data workbook using the method described above. The issue here, then, is that I don’t want to have to make everyone open up the data workbook before the template workbook, so I’m instead aiming to write a batch file that my colleagues will launch so that the data workbook is opened before the template.
The batch file I have written does this just fine, but when the template is opened it requires that links be updated; not what is wanted! However, if I manually open the data workbook then the template workbook, no update is required. Any ideas?
@eruditio
Have you tried clicking “start up prompt” in “Edit links”? You can then choose to update the links automatically
Deb, please help, I’ve been running around the internet forever and can’t figure this out. I’ve had a source document (MoM Data.xlsx) and template document (_MoM Template.xlsx) that have been linked for years with dropdowns working just fine. As of 3 weeks ago, I get an error that “…one or more links cannot be updated…”. When I look to see where it’s trying to pull the source from, it seems to have put an extra “Server’s Documents” in the path. No matter what direction I try to take I can’t: break links, change the source to a different file, edit the path to the proper file, etc. Any ideas?
@Chad, that’s odd, and I haven’t seen that happen before. Can you delete the bad link and rebuild it?
I have but that just let’s me ignore the error. It doesn’t actually fix the connection issue.
