All cell contents initially use the same default formatting, which can make it difficult to read a workbook with a lot of information. Basic formatting helps personalize the appearance of your workbook, allowing you to draw attention to specific sections and make your content easier to read and understand.
You can also apply number formatting to tell Excel exactly what type of data you’re using in your workbook, such as percentages (%), currency ($), and more.
Changing the Font
By default, the font in every new workbook is set to Calibri. However, Excel offers many other fonts to help you customize the text in your cells.
In the example below, we’ll format the title cell to distinguish it from the rest of the worksheet.
- Select the cell(s) you want to modify.

- Click the drop-down arrow next to the Font command on the Home tab.
The font menu will appear. - Select the desired font. A live preview will appear as you hover over different options.
In our example, we’ll choose Georgia.

- The text will update to the selected font.

For professional workbooks, choose an easy-to-read font. Besides Calibri, good options include Cambria, Times New Roman, and Arial.
Changing the Font Size
- Select the cell(s) you want to modify.

- Click the drop-down arrow next to the Font Size command on the Home tab.
The font size menu will appear. - Select the desired font size. A live preview will appear as you hover.

You can also use the Increase Font Size and Decrease Font Size buttons or type a custom size using your keyboard.

Changing the Font Color
In Excel, you can add visual interest by changing the font color. While spreadsheets are often used to display specific data, that doesn’t mean they have to look plain. Adding a touch of color can make your sheets more appealing and easier to read.
You can choose a theme color, a standard Excel palette color, or create a custom one.

To access more color options, click More Colors at the bottom of the menu.

Adding a Background Color to a Cell Range
You can make a range stand out by applying a background color.
If you want to change the background color based on cell values (e.g., red for negative, green for positive), conditional formatting is more suitable.
You can use a theme color, a standard color, or a custom one.
- Select the range you want to format.
- Click the Home tab.
- Click the Fill Color drop-down list.


- Click a theme color or a standard color.
Excel applies the fill color to the selected range.
To remove the background color, select No Fill.

Using Bold, Italic, and Underline Commands

- Click the Bold (B), Italic (I), or Underline (U) button on the Home tab.
In our example, we’ll bold the selected cells.

You can also use keyboard shortcuts:
