Excel provides quite a few predefined number formats that you can use. There may be times when you need a number format that isn't pre-defined by Excel. Fortunately, you can create custom number formats that provide you with complete control over how numbers appear.

Custom number formats are created through the use of formatting codes. Before you can create your own custom number formats, you need to understand how the formatting codes work. The next several tips examine each of the formatting codes understood by Excel. (See here, here, and here.) If you study these codes, you will be ready to create your own formats.

Once you understand formatting codes, you can start to create your own formats. This is done by first selecting the cells you want to format and then choosing Cells from the Format menu. When you see the Format Cells dialog box, make sure you select the Number tab and select Custom as the number category, which is the bottom choice in the Category list. (See Figure 1.)

In the Type field at the right side of the dialog box is the code for the currently selected number format. You can change these codes or simply enter your own codes. By adding conditionals and colors to your formats, you can get very complex, indeed. Whatever you enter is automatically added to the Custom category, and can be used anywhere within the workbook.
