Excel’s AutoFill feature is based on the program’s ability to spot patterns in the data that you enter. For example, if you type “Week 1″ in a given cell, you can have Excel automatically fill in “Week 2″, “Week 3″, etc. simply by dragging the AutoFill handle. This is to be found in the bottom right of the cell. If the cursor moves over it, the cursor changes appearance to a plus sign (+). When it changes you simply click, hold, drag in any direction and Excel will spot the pattern and maintain it to generate automatic data entries.
Each time you use the AutoFill handle Excel displays the AutoFill Options drop down menu just below the last cell which has been automatically created. If the program has not entered the data you wanted it to, just choose one of the entries in the AutoFill Options to tell it what you wanted it to do. For example, if you choose Copy Cells, Excel will generate 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.
As well as these built-in lists, Excel allows you to create your own custom lists. For example, suppose you work for a company that has branches in several towns. It’s a safe bet that you’ll need to list these towns quite frequently in your spreadsheets. You could therefore save yourself considerable time by setting up the towns as a custom list.
To create a custom list, simply select some cells that contain the information. Next, choose Excel options by clicking on the Office button. Click “Edit Custom Lists” in the “Popular” tab. Excel lists the contents of the cells that were highlighted. To set up the selected data as a custom list, simply click on the “Import” button.
This custom list can now be used in any of our worksheets, not just the sheet that contained the original information. Whenever we need out list, we simply type the first value. We then use the AutoFill handle to generate the remaining entries. When using AutoFill, you can drag in any direction and you don’t have to start with the first element 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.
