Loading and Exiting Spreadsheet Packages

Microsoft Office Excel 2010 offers various options for launching and closing the program. To open Excel, users can either use the Start menu or a desktop shortcut. Once the program is launched, a new, blank workbook is displayed and ready for data entry.

To exit Excel, there are several methods available. Firstly, users can choose to exit the program by clicking on the “File” tab and selecting “Exit”. Alternatively, they can use the keyboard shortcut “Alt+F4” to close the program. Users can also click on the “Close” button (the X) located at the upper-right corner of the Excel 2010 program window.

It is important to note that when closing Excel after working on a workbook, the latest changes must be saved. Otherwise, an alert box will be displayed, asking whether the changes should be saved. To save any changes made before exiting Excel, users can click on the “Save” button. If the user does not wish to save their changes, they can click on “Don’t Save”.
