Takeaways
This video explains how to use 3D formulas in Excel to quickly aggregate data from multiple worksheets. The example demonstrates summing sales figures for several employees across different product categories and months onto a summary sheet. The process involves starting a SUM function, clicking the first worksheet in the desired range, holding Shift while clicking the last worksheet, and then selecting the relevant cell, creating a formula like SUM('Sheet1:SheetN'!B2). The explanation highlights that the formula works on a physical range of tabs, meaning rearranging worksheets can affect the calculation. The video also shows how to copy the 3D formula to fill the entire summary table efficiently.
Mastering 3D Formulas in Excel
What is a 3D formula in Excel?
A 3D formula in Excel is a method to summarize data that spans across multiple worksheets within the same workbook or even across different workbooks. Instead of referencing individual cells on different sheets, it allows you to reference a range of worksheets and a specific cell or range within those sheets simultaneously.
What is the primary purpose of using 3D formulas?
The primary purpose of using 3D formulas is to easily consolidate and summarize data from identically structured sheets. This is particularly useful when you have similar data recorded across different periods, employees, or locations, and you want to calculate totals, averages, or other aggregations without manually referencing each sheet.
How do you construct a basic 3D SUM formula?
To construct a basic 3D SUM formula, you start by typing =SUM(. Then, click on the tab of the first worksheet you want to include in the calculation. Next, while holding down the Shift key, click on the tab of the last worksheet you want to include. Finally, click on the cell or range of cells on one of these sheets that you want to sum across the selected range of sheets. Close the parenthesis and press Enter. Excel will display the formula in the format =SUM('FirstSheet:LastSheet'!CellReference).
Can 3D formulas be used with functions other than SUM?
Yes, 3D formulas can be used with a variety of aggregation functions in Excel, such as AVERAGE, COUNT, MAX, and MIN, provided they are applicable to referencing a range of sheets. The syntax remains similar, replacing SUM with the desired function.
How does the order of worksheets affect the calculation of a 3D formula?
The order of worksheets is crucial when using 3D formulas. The formula calculates across the sheets physically located between the first and last sheet referenced in the formula's range. If you move a sheet outside of this physical range (i.e., before the first sheet or after the last sheet referenced), its data will no longer be included in the calculation. Similarly, adding new sheets within the specified range will automatically include their data in the calculation.
Can you copy and paste 3D formulas?
Yes, you can copy and paste 3D formulas using the fill handle, just like standard formulas. If the formulas are relative, Excel will adjust the cell reference within the 3D range based on where you paste the formula, allowing you to quickly apply the same calculation logic across different rows or columns on your summary sheet.
What is the format of a 3D formula referencing a range of sheets and a single cell?
The format of a 3D formula referencing a range of sheets and a single cell is typically FunctionName('FirstSheet:LastSheet'!CellReference). For example, =SUM('Bob:KC'!B2). The sheet names are enclosed in single quotes if they contain spaces or special characters, followed by a colon separating the first and last sheet in the range, an exclamation mark, and finally the cell reference.
What should you be mindful of when using 3D formulas, especially regarding sheet organization?
When using 3D formulas, you should be mindful that the calculation is based on the physical order of the sheets within the workbook. Moving sheets in or out of the range specified in the formula will directly impact the results. Therefore, maintaining a consistent and logical arrangement of your worksheets is essential for accurate calculations with 3D formulas.

Quiz Answer Key
The primary purpose is to summarize data across multiple worksheets or even workbooks.
The worksheets contain sales information for three employees (Bob, Sarah, and Casey) for the first half of the year, broken down by products A, B, and C, and are set up in a similar format.
You initiate a 3D formula by typing an equals sign (=) followed by the function name, such as "sum".
The Tab key is pressed after typing the function name to acknowledge it in Excel.
The range of worksheets is selected by clicking on the first worksheet tab, holding down the Shift key, and then clicking on the last worksheet tab in the desired range.
The formula bar displays the function name followed by the range of worksheet names separated by "through", and then the cell reference (e.g., =SUM(Bob:KC!B2)).
The example demonstrates filling the rest of the summary table by using the fill handle to drag the formula down and across after creating the initial 3D formula.
If a worksheet within the defined range is moved outside of that range, its data will no longer be included in the 3D formula's calculation.
"Physical range" refers to the literal order and position of the worksheet tabs within the workbook.
If a worksheet previously moved out of the range is moved back into the range, the summary data will automatically update to include its information again.
Glossary of Key Terms
3D Formulas: Formulas in Excel that refer to the same cell or range of cells on multiple worksheets. They allow for calculations and summarization of data across different sheets within a workbook, or even between workbooks.
Worksheets: Individual sheets within an Excel workbook, typically represented by tabs at the bottom of the Excel window.
Workbook: An Excel file containing one or more worksheets.
Summarize Data: To consolidate and present key figures or totals from a larger set of data.
