Excel 2007: Use these three techniques to turbo charge filtering
By David Ringstrom, CPA
Did you know Excel 2007 has a hidden command that enables you to filter a list with just one mouse click? And that there are two ways to sum just the visible rows in your filtered list? Read on to discover these time saving techniques.

Table 1: Use this sample t-shirt sales data to explore Filtering in Excel 2007.
Filter versus Autofilter
As you're probably aware, the Filter command appears on both the Home and Data tabs of the Excel 2007 ribbon. However, going this route to filter a list usually means multiple mouse clicks. Instead, I recommend that you add the AutoFilter command to your Quick Access Toolbar:
- Right-click anywhere on the Excel 2007 ribbon and, then choose Customize Quick Access Toolbar.
- As shown in Figure 1, choose Commands Not In the Ribbon, and then add AutoFilter to your Quick Access toolbar. Close the dialog box shown in Figure 1.

Although it's similar in name to the Filter command, AutoFilter has a special capability: it instantly filters your list based on the contents of the currently selected cell:
- Copy and paste the sample data from Table 1 into a blank worksheet.
- Click on cell B14 — which contains the word green — and then click the AutoFilter button that you added to your Quick Access toolbar. As shown in Figure 2, your list should now show only green T-shirt sales.
Caveat: AutoFilter only allows you to filter for a single value, such as the word green, so you'll still need to use the filter drop-down lists for more complex filtering.

Important: Although AutoFilter turns on the arrows, you must still choose Sort & Filter, and then Filter to turn off the filtering arrows.
Analyze Visible Rows
Now let's look at two ways to analyze data as you filter it. First, many users overlook the fact that Excel 2007 automatically displays the total of selected cells in the status bar at the bottom of the screen, as shown in Figure 3. If you don't see this total, right-click on the status bar and enable the Sum option. Excel usually also displays these statistics, too: Average, Count, Numerical Count, Minimum, and Maximum.
Figure 3: The status bar generally gives you an instant total for the selected cells. (Click on image to expand.)
You can also accomplish this by using the SUBTOTAL function. To do so, enter this formula in cell C23:
The 9 instructs SUBTOTAL that we want to sum. As shown in Figure 4, Excel automatically displays the additional options as you type the formula. SUBTOTAL is similar to SUM, but has a special capability of only tallying visible rows.
Figure 4: The SUBTOTAL function has several capabilities.
For comparison, enter this formula in cell C24:
Now, filter the list for Orange T-shirts. As shown in Figure 5, SUBTOTAL should return 25,157, while SUM always returns 99,559, regardless of how the list is filtered. SUM always tallies all rows, regardless of their hidden status. SUBTOTAL has other interesting capabilities, which I'll explore soon in a separate article.
