Excel 2010: The Missing Manual (Paperback)

1. Page break preview -- In page break preview mode (choose View --> Workbook Views --> Page Break Preview) you can see how your printed worksheet will be split across multiple pages. But even more valuable is the ability to drag a page break to a new place. For example, if you spot some data off to the right side that doesn't fit on your page, you can drag the page break to the right so that it does. When you do this, Excel scales down your entire worksheet to fit the information you want.

2. Recovering unsaved work -- Ever start a new workbook, and then forget to save it when you close Excel in a hurry? Now you can get your lost work back. Just choose File --> Info, click the Manage Versions button, and choose Recover Unsaved Workbooks to find the unsaved spreadsheets that Excel stores automatically.

3. Lookup formulas -- If you understand how to use them, lookup formulas give you a powerful way to copy information from one part of a spreadsheet to another. For example, you can use lookup formulas to create an invoice that automatically inserts the correct product and price information when you type in a product code. Ordinarily, you'd expect this sort of solution to need macros or Visual Basic, but it doesn't.

4. Formula tracing -- Sometimes formulas go wrong, and the result is information that doesn't make sense (or an error code). Excel's formula tracing feature is a big help if this happens in a complex spreadsheet. When you use it, Excel adds arrows that point from the source cells to the formula that uses these cells. Essentially, formula tracing gives you a way to graphically "see" how your formula connects to the rest of your data, and it often helps you find the troublemaking cell that's causing the problem.

5. Charting tricks -- Charts tell a story with your data, and there are plenty of tricks that you can use to make them present that story more clearly and conclusively. For example: changing a chart's scale, adding an overlay, changing the fill of a specific series, inserting text and graphics directly on the chart surface, and so on, all have a dramatic effect. They make the difference between a chart that conveys a useful insight, and one that's just a bit of spreadsheet decoration.
