Files from Excel are called workbooks. You will need to build a new workbook anytime you begin a new project in Excel. You may choose to create a new workbook or open a new workbook or open an existing workbook with either a blank workbook or a predesigned template.
Creating a new blank workbook:
- When you select the File tab, the backstage view will appear.

- Choose New and click Blank workbook.

- There will be a new blank workbook.
Opening an existing workbook:
You will also need to open a workbook that was previously saved, in addition to creating new workbooks.
- Browse to Backstage view, and then click Open.

- Choose Computer, and then click Browse.

- The Open dialog box will display. Locate and pick your workbook, then click Open.

If you have opened the desired workbook recently, instead of searching for a file, you can browse your recent workbooks.
