Creating formulas that reference cells in other workbooks
One of the strengths of Excel is that you aren’t limited to using cells from the current workbook in your formulas. If you want, you can use data from any other workbook in your calculations. For example, you might have a workbook in which you track monthly advertising sales for your newsletter. If you want to create a new workbook to summarize all income and expenses for your publication, you can do so. By letting you create formulas that reference cells from more than one workbook, Excel makes it easy for you to organize your workbooks so that each workbook holds data about a specific subject. Not only can you find the data easily, you can reference it anywhere else.
After you create links between workbooks, you can have Excel update your calculation if the data in the linked cell changes. You can also change the cell to which you linked, or if the workbook with the cell to which you linked has been moved or deleted, you can delete the link and have Excel store the last value from the calculation.
