· Describe the uses of Excel
· Define key spreadsheet terms
Microsoft Excel is the electronic spreadsheet program within the Microsoft Office suite. An electronic spreadsheet is an app you use to perform numeric calculations and to analyze and present numeric data. One advantage of a spreadsheet program over pencil and paper is that your calculations are updated automatically, so you can change entries without having to manually recalculate. Table 1-1 shows some of the common business tasks people accomplish using Excel. In Excel, the electronic spreadsheet you work in is called a worksheet , and it is contained in a file called a workbook , which has the file extension .xlsx. At R2G, you use Excel extensively to track finances and manage corporate data.

When you use Excel, you have the ability to:
· Quick Tip
You can also use the Quick Analysis tool to easily create charts and other elements that help you visualize how data is distributed.
Enter data quickly and accurately
With Excel, you can enter information faster and more accurately than with pencil and paper. Figure 1-1 shows a payroll worksheet created using pencil and paper. Figure 1-2 shows the same worksheet created using Excel. Equations were added to calculate the hours and pay. You can use Excel to recreate this information for each week by copying the worksheet’s structure and the information that doesn’t change from week to week, then entering unique data and formulas for each week.

· Recalculate data easily
Fixing typing errors or updating data is easy in Excel. In the payroll example, if you receive updated hours for an employee, you just enter the new hours and Excel recalculates the pay.
· Quick Tip
Power users can perform more complex analysis using Business Intelligence tools such as Power Query and new forecasting functions.
Perform what-if analysis
The ability to change data and quickly view the recalculated results gives you the power to make informed business decisions. For instance, if you’re considering raising the hourly rate for an entry-level tour guide from $12.50 to $15.00, you can enter the new value in the worksheet and immediately see the impact on the overall payroll as well as on the individual employee. Any time you use a worksheet to ask the question “What if?” you are performing what-if analysis . Excel also includes a Scenario Manager where you can name and save different what-if versions of your worksheet.
· Change the appearance of information
Excel provides powerful features, such as the Quick Analysis tool, for making information visually appealing and easier to understand. Format text and numbers in different fonts, colors, and styles to make it stand out.
· Create charts
Excel makes it easy to create charts based on worksheet information. Charts are updated automatically in Excel whenever data changes. The worksheet in Figure 1-2 includes a 3-D pie chart.
· Share information
It’s easy for everyone at R2G to collaborate in Excel using the company intranet, the Internet, or a network storage device. For example, you can complete the weekly payroll that your boss, Yolanda Lee, started creating. You can also take advantage of collaboration tools such as shared workbooks so that multiple people can edit a workbook simultaneously.
· Quick Tip
The flash fill feature makes it easy to fill a range of text based on examples that are already in your worksheet. Simply type [Ctrl][E] if Excel correctly matches the information you want, and it will be entered in a cell for you.
Build on previous work
Instead of creating a new worksheet for every project, it’s easy to modify an existing Excel worksheet. When you are ready to create next week’s payroll, you can open the file for last week’s payroll, save it with a new filename, and modify the information as necessary. You can also use predesigned, formatted files called templates to create new worksheets quickly. Excel comes with many templates that you can customize.
