Part VII: Appendixes
The following number format is useful for telephone numbers. Values greater than 9999999 (that
is, numbers with area codes) are displayed as (xxx) xxx-xxxx. Other values (numbers without
area codes) are displayed as xxx-xxxx.
[>9999999](000) 000-0000;000-0000
For U.S. ZIP codes, you might want to use the format string that follows. This displays ZIP codes using
five digits. But if the number is greater than 99999, it uses the ZIP-plus-four format (xxxxx-xxxx).
[>99999]00000-0000;00000
Coloring values
Custom number format strings can display the cell contents in various colors. The following format
string, for example, displays positive numbers in red, negative numbers in green, zero values
in black, and text in blue:
[Red]General;[Green]-General;[Black]General;[Blue]General
Following is another example of a format string that uses colors. Positive values display normally;
negative numbers and text cause Error! to display in red.
General;[Red]”Error!”;0;[Red]”Error!”
Using the following format string, values that are less than 2 display in red. Values greater than 4
display in green. Everything else (text, or values between 2 and 4) displays in black.
[Red][4]General;[Black]General
As seen in the preceding examples, Excel recognizes color names such as [Red] and [Blue]. It
also can use other colors from the color palette, indexed by a number. The following format
string, for example, displays the cell contents using the 16th color in the color palette:
[Color16]General
Excel’s conditional formatting is a much better way to color text in a cell based on the
cell’s value.
