A reference that refers to the same cell or range on multiple sheets is called a 3D reference. A 3D reference is a useful and convenient way to reference several worksheets that follow the same pattern and contain the same type of data, such as when you consolidate budget data from different departments in your organization.
What do you want to do?
Learn about a 3D reference
You can use a 3D reference to add up budget allocations between three departments, Sales, HR, and Marketing, each on a different worksheet, by using the following 3D reference:
=SUM(Sales:Marketing!B3)
You can even add another worksheet, and then move it into the range that your formula refers to. For example, to add a reference to cell B3 in the Facilities worksheet, move the Facilities worksheet between the Sales and HR worksheets by dragging its tab, as shown in the following example.
Because your formula contains a 3D reference to a range of worksheet names, Sales:Marketing!B3, all worksheets in the range are included in the new calculation.
Learn how 3D references change when you move, copy, insert, or delete worksheets
The following examples explain what happens when you insert, copy, delete, or move worksheets that are included in a 3D reference. The examples use the formula =SUM(Sheet2:Sheet6!A2:A5) to add cells A2 through A5 on worksheets 2 through 6.
Insert or copy If you insert or copy worksheets between Sheet2 and Sheet6 (the endpoints in this example), Excel includes all values in cells A2 through A5 from the added worksheets in the calculations.
Delete If you delete worksheets between Sheet2 and Sheet6, Excel removes their values from the calculation.
Move If you move worksheets from between Sheet2 and Sheet6 to a location outside of the referenced worksheet range, Excel removes their values from the calculation.
Move an endpoint If you move Sheet2 or Sheet6 to another location in the same workbook, Excel adjusts the calculation to include the new worksheets between them unless you reverse the order of the endpoints in the workbook. If you reverse the end points, the 3D reference changes the endpoint worksheet. For example, say that you have a reference to Sheet2:Sheet6: If you move Sheet2 so that it's after Sheet6 in the workbook, the formula will adjust to point to Sheet3:Sheet6. If you move Sheet6 in front of Sheet2, the formula will adjust to point to Sheet2:Sheet5.
Delete an endpoint If you delete Sheet2 or Sheet6, Excel removes the values on that worksheet from the calculation.
Create a 3D reference

Click the cell where you want to enter the function.
