A blank worksheet in a new workbook.
When you start Excel, you open a file that's called a workbook. Each new workbook comes with three worksheets, like pages in a document. You enter data into the worksheets. (Worksheets are sometimes called spreadsheets.)
Each worksheet has a name on its sheet tab at the bottom left of the workbook window: Sheet1, Sheet2, and Sheet3. You click each sheet tab to view a worksheet.
It's a good idea to rename the sheet tabs to make the information on each sheet easier to identify. For example, you might have sheet tabs called January, February, and March for budgets or student grades for those months, or Northcoast and Westcoast for sales regions, and so on.
You can add additional worksheets if you need more than three. Or if you don't need as many as three, you can delete one or two (but you don't have to). And you can use keyboard shortcuts to move between sheets.
You'll see how to do all that in the practice at the end of the lesson.
You may be wondering how to create a new workbook. Here's how: Click the Microsoft Office Button at the upper left. Then click New. In the New Workbook window, click Blank workbook.
