Formatting can make your spreadsheet easier to read and understand. Common formatting tools include bold, italic, underline, color-coding, borders, and cell shading. You can also adjust number formatting, such as percentages, currency, or date formatting.

Spreadsheet applications such as Microsoft Excel, Google Sheets, and others are not just about performing calculations or data analysis. They also provide a comprehensive set of tools for customizing the appearance of your spreadsheet data, making it more readable, understandable, and visually appealing. This is where spreadsheet formatting comes into play. This article explores the numerous formatting options available in spreadsheet applications, providing expert users with guidance on how to optimize the presentation of their data.

The Basics of Spreadsheet Formatting

At the most basic level, formatting in a spreadsheet involves altering the appearance of cells and the data within them. This can include changing the font type, size, or color, adjusting the cell background color, or modifying the alignment of the text within the cells.

These changes can be applied using the toolbar in your spreadsheet application, usually found at the top of the screen. For instance, to change the font color of a cell, you would select the cell, click on the font color button in the toolbar, and choose your desired color. This is a simple example, but there are many more formatting options available.

Understanding Cell Formats

Cell formats define how the data within a cell is displayed. It doesn't change the data itself, but rather how it's presented. For instance, you can format a cell to display numbers as percentages, dates, currency, and so on.

To change the cell format, you can usually right-click on a cell and choose "Format cells" (the exact steps may vary slightly between different spreadsheet applications). This will open a dialog box where you can select your desired format.

You can also use cell formats to control the display of text data. For instance, you can use the "text" format to ensure that numbers are treated as text, preventing the spreadsheet from performing any calculations with them.

Working with Styles and Themes

Many spreadsheet applications provide the option to apply pre-defined styles or themes to your spreadsheet. These are sets of formatting options that have been designed to work well together, providing a quick and easy way to create a visually consistent and attractive spreadsheet.

Styles can often be applied at both the cell level and the spreadsheet level. Cell styles might include options for title cells, header cells, and data cells, among others. Spreadsheet-level themes can include coordinated colors, fonts, and other elements that apply to the entire spreadsheet.

Conditional Formatting

Conditional formatting is a powerful tool that allows you to change the formatting of cells automatically based on their contents. For instance, you could use conditional formatting to highlight cells that contain values above a certain threshold, or to color-code cells based on their value.

Setting up conditional formatting involves defining one or more rules, each of which includes a condition and a formatting style to apply when that condition is met. For example, a rule could be "If the cell value is greater than 100, color the cell green."

You can usually find the conditional formatting options in the menu or toolbar of your spreadsheet application. Although the specific steps to set up conditional formatting can vary, they generally involve selecting the cells to format, choosing "Conditional formatting" from the menu, and defining your rules.

Data Bars, Color Scales, and Icon Sets

These are specific types of conditional formatting that provide additional ways to visualize data in your spreadsheet. Data bars can be used to create a sort of in-cell bar chart, with the length of the bar representing the value in each cell.

Color scales change the background color of cells based on their value, effectively creating a heat map. This can be a useful way to visualize the distribution of values across a range of cells.

Icon sets allow you to add icons to cells based on their value, providing a visual indication of each cell's value relative to the others.

Indenting, Text Wrap, and Merge & Center

Aside from modifying color or adding conditional formatting, other elements play a crucial role in making your data presentable and organized. One of them is text indentation. By indenting text, you can visually separate different sections of your spreadsheet, making it easier to read and navigate.

Text wrapping is another essential formatting tool. When the contents of a cell extend beyond the cell's width, you can use the wrap text feature to make the entire content visible by increasing the cell's height.

Lastly, the "Merge & Center" feature allows you to combine multiple cells into one and center the text within it. This is often used for creating headers that span across several columns or rows.

Custom Number Formats

While spreadsheet applications come with a variety of built-in number formats, you also have the ability to define your own. Custom number formats provide a way to display numbers exactly how you want them, including adding prefixes or suffixes, controlling the number of decimal places, and more.

To create a custom number format, you typically right-click on a cell, choose "Format Cells", and then select "Custom" from the category list. You can then define your format in the "Type" input box.

Styles and Templates

For more consistent and efficient formatting, most spreadsheet programs allow you to define styles and templates. A style is a set of formatting characteristics that you can apply simultaneously to a cell or range of cells. Once you've defined a style, you can apply it with just a few clicks, ensuring consistent formatting throughout your spreadsheet.

Templates, on the other hand, are pre-formatted spreadsheets designed for specific tasks or types of data. They often include a mix of predefined cells, formulas, and formatting. By saving your spreadsheet as a template, you can reuse it whenever you need to perform the same task, saving you time and ensuring consistency.

Print Formatting

Finally, it's worth noting that spreadsheets aren't just for screen use - often, you'll need to print your data. Print formatting options help ensure that your spreadsheet looks as good on paper as it does on the screen.

This can include defining print areas, setting page margins, adjusting orientation, setting up headers and footers, and more. Additionally, you can control whether gridlines and row and column headers are printed, and define how your data is split across multiple pages.


Formatting is an integral part of spreadsheet use that enhances the readability and understanding of your data. By mastering formatting options like basic cell formats, conditional formatting, custom number formats, and print formatting, you can ensure your spreadsheets are both functional and visually appealing. Remember, the key to effective formatting is to enhance your data's readability without overshadowing the data itself. As with many aspects of spreadsheets, less is often more.
