Dependent Drop Down Lists in Excel

In Excel, you can set up drop down lists that are dependent on the selection made in another cell. In this example, you select a region in column B, and only the customers in that region are in the drop down list in column C.



One way to accomplish this is with named ranges and the INDIRECT function, as explained here: Data Validation — Create Dependent Lists. That method works well if there are only a few options in the first column.

For a longer list of items, it might be difficult, or impossible, to set up all the named ranges that you need, and to maintain all those lists.

To make things easier, this tutorial uses the OFFSET function, to extract related items from a sorted list.


The only restriction is that the main column has to be sorted, so that all the items are grouped together.


Updated for Excel Tables

The original version of this tutorial used lists on the worksheet, and I have updated it to use named Excel tables. Now, when you name the ranges, they are connected to the tables, so they adjust automatically if the table size changes.


Cross Validation

The Region column uses a simple list as the source for its drop down, as long as no customer has been selected. However, if a customer name is in column C, the Region drop down only shows the region for that customer.

If you want to start over, clear out both cells in the row, and select a region, then a customer.
