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.
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 figure:
Because your formula contains a 3D reference to a range of worksheet names, Sales:Marketing!B3, all worksheets in the range are part of the new calculation.
Learn how 3D references change when you move, copy, insert, or delete worksheets
The examples below explain what happens when you insert, copy, delete, or move worksheets that are included in a 3D reference. Each of these 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 in the constituent 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, you may 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
Follow these steps:

Click the cell in which you'll enter the function.

Type a = (equal sign), followed by the name of the function (see the table below), and then an opening parenthesis.

Click the tab for the first worksheet that you want to reference.

Hold down the Shift key then click the tab for the last worksheet that you want to reference.

Select the cell or range of cells that you want to reference.

Complete the formula, and then press Enter.
You can use the following functions in a 3D reference:

Create a name for a 3D reference
Follow these steps:

On the Formulas tab, click Define Name (in the Defined Names group).

In the New Name popup window, enter the Name for your reference. Names can be up to 255 characters in length.

In the Refers to list, choose the equal sign (=) and the reference, then press the Backspace key.

Click the tab for the first worksheet that you want to reference.

Hold down the Shift key and click the tab of the sheet of the reference.

Select the cell or range of cells that you want to reference.
