All cell content uses the same formatting by default, which can make it difficult to read a workbook with a lot of information. Basic formatting can customize the look and feel of your workbook, allowing you to draw attention to specific sections and making your content easier to view and understand. You can also apply number formatting to tell Excel exactly what type of data you’re using in the workbook, such as percentages (%), currency ($), and so on
In other words, when we format cells in Excel, we change the appearance of a number without changing the number itself. We can apply a number format (0.8, $0.80, 80%, etc) or other formatting (alignment, font, border, etc).
1. Enter the value 0.8 into cell B2.
By default, Excel uses the General format (no specific number format) for numbers. To apply a number format, use the 'Format Cells' dialog box.
2. Select cell B2.
3. Right click, and then click Format Cells (or press CTRL + 1).
The 'Format Cells' dialog box appears.
4. For example, select Currency.
Note: Excel gives you a life preview of how the number will be formatted (under Sample).
5. Click OK.
Cell B2 still contains the number 0.8. We only changed the appearance of this number. The most frequently used formatting commands are available on the Home tab.
6. On the Home tab, in the Number group, click the percentage symbol to apply a Percentage format.
7. On the Home tab, in the Alignment group, center the number.
8. On the Home tab, in the Font group, add outside borders and change the font color to blue.
