Creating a basic worksheet is only the first step toward mastering
Excel. If you plan to print your worksheet, email it to colleagues,
or show it off to friends, you need to think about whether your
worksheet is formatted in a viewer-friendly way. A careful use of
color, shading, borders, and fonts can make the difference between a
messy glob of data and a worksheet that's easy to
work with and understand.
But formatting isn't just about deciding, say, where
and how to make your text bold. Excel also lets you control the way
numerical
values are formatted. In fact,
there are really two fundamental aspects of formatting in any
worksheet:
-
Cell appearance. Cell
appearance includes
cosmetic details like color, typeface, alignment, and borders. When
most people think of formatting, they think of cell appearance first.
-
Cell values. Cell
value formatting controls the way Excel
displays numbers, dates, and times. For numbers, this includes
details like whether to use scientific notation, the number of
decimal places displayed, and the use of currency symbols, percent
signs, and commas. With dates, cell value formatting determines what
parts of the date are shown in the cell, and in what order.
Cell value formatting is in many ways more
significant than cell appearance, because it can change the meaning
of your data. For example, even though 45%, $0.45, and 0.450 are all
the same number, your spreadsheet readers will see a failing test
score, a cheap price for chewing gum, and a world-class batting
average, respectively.
Keep in mind that regardless of how you format
your cell values, Excel maintains an unalterable
value for every number entered. For more on how
Excel internally stores numbers see the box on Sidebar 4.1.
In this chapter, you'll learn about cell value
formatting, and then unleash your inner artist with cell appearance
formatting. Finally, you'll learn the most helpful
ways to use formatting to improve a worksheet's
readability and how to save time with nifty features like AutoFormat,
styles, and conditional formatting.
