Excel 2007 AutoFill And Custom Lists

By Matthew Fletcher

Excel's AutoFill facility relies on the program's ability to recognize patterns in the values that you enter. For example, say you type "Week 1" in a cell; you can have the program automatically enter "Week 2", "Week 3", etc. by dragging the AutoFill handle. This is situated in the bottom right of the cell. When the cursor moves over it, the cursor changes appearance to a plus sign (+). At this point you simply click, hold, drag in any direction and Excel will pick up the pattern and reproduce it to create automatic data entries.

Whenever you use the AutoFill handle Excel displays the AutoFill Options drop down menu just below the last cell which has been automatically generated. If the program has not entered the correct data, you can choose one of the entries in the AutoFill Options to tell it what you actually meant it to do. For example, if you choose Copy Cells, you simply get an exact copy of what was in the original cell.

Excel is also capable of automatically entering an arbitrary series of data using a feature called Custom Lists. There are certain lists built into Excel, for example, the months of the year. To use the AutoFill feature, you need to enter the first value in the list, for example, "January" or "Jan". Next, you drag the AutoFill handle (located in the bottom right of the cell) in any direction to have Excel automatically enter the rest of the custom list.

In addition to Excel's built-in lists, you can also create your own custom lists. For example, let's say we work for a company that has branches in several towns. We would almost certainly need to list these towns quite frequently in our spreadsheets. We could save ourselves a fair amount of time by setting up the towns as a custom list.

To do this, simply select cells in one of your worksheets that contain the information. Next, click on the Office button and choose Excel options. Click on "Edit Custom Lists" in the "Popular" category. Excel displays the contents of the cells that we highlighted. To convert the selected data into a custom list, we simply click on the "Import" button.

Having created a custom list, you can use it in any of your worksheets, not just the one that contained the original information. To conjure up the entries in the list, simply enter the first value. Next, drag the AutoFill handle and Excel will generate the remaining entries. When you use this facility, you are able to drag in any direction and you don't have to start with the first entry in the custom list.

Custom lists can also be created directly in the "Custom Lists" dialog box. To do this, click on the "List Entries" button and type the entries separated by a carriage return. When you've finished entering the list, click on the Add button.

To delete an unwanted custom list, just click on it and press the "Delete" button. Excel checks that you want to delete the list and when you click "OK", the custom list is removed. - 16069
