Unit 9: Multi-Page Spreadsheets In this unit, you will learn how to work with large workbooks, and this unit will highlight various features that will make working in Excel® more productive. We will explore formulas and functions that drill downthrough multiple worksheets for their answers. When a workbook gets large, it is important to understand how to format each worksheet tab so that information is easier to find. You learned about formatting worksheet tabs in Subunit 2.2.2. If needed, reread that section.
Unit 9 Time Advisory

Unit9 Learning Outcomes
Upon successful completion of this unit, you will be able to:
- describe how to write a formula that drills down through multiple
worksheets;
- create and format multiple worksheets at one time; and
- describe how to group and ungroup worksheets.
9.1 3D Formulas 3D formulas are used to combine information from multiple worksheets onto one worksheet for an answer. Information can be taken from as many worksheets as needed. When using a 3D formula, it is easier if your worksheets are adjacent to each other in the workbook. It makes it easier because the syntax of the formula is easier to read. Each worksheet needs to be named in the formulas if working with non-adjacent workbooks, and this can get cumbersome to write as well as read. Let’s say you are working in Sheet 7 and want to add two numbers from two other worksheets in your workbook. The 3D formula will look like this: =Sheet1!C3+Sheet4!$C$6. This will add the number in Sheet 1 cell C3 to the number in Sheet 4 cell C6 and place it in the worksheet you are in, Sheet 7. The exclamation point (!) is needed in the formula at the end of each sheet name followed by the cell reference, which can either be relative or absolute. You learned about relative (C6) and absolute ($C$6) referencing in Unit 3. If you want to add all of the cells B3 from all worksheets in the workbook and they are adjacent to each other, it would look like: =sum(Sheet1:Sheet6!$B$3). This formula tells us that it is adding each number in B3 in each of the worksheets 1 through 6.

Instructions: Watch the video about 3D formulas. When you are finished, open up your own spreadsheet software and try to create some 3D formulas.
Completing this assignment should take approximately 45 minutes.
9.2 Formulas Across Workbooks Now that you’ve created 3D formulas within one workbook using various worksheets, let’s look at creating a formula that uses two workbooks. This is a little bit more complicated because you have to be cognizant of where the workbooks are saved and if they are linked. If the workbooks are linked, they shouldn’t be moved once the formula is created or the formula may not work. If they are moved, both need to be moved so that the link can stay useful. When you create formulas between workbooks, you can either link them or just create the formula without linking them. But, if they are notlinked and you change or update a number in one workbook, the formula you created will not be updated with the new information. This may make more sense after you have watched the video.
