Final answer:
In Microsoft Excel, the Format Cells dialog box launcher is located in the Font, Alignment, or Number groups on the Home tab. It is used to customize cell formatting.
Step-by-step explanation:
The Format Cells dialog box launcher can be accessed in Microsoft Excel on the Home tab. When you're in the Home tab, you'll find this option in the Font, Alignment, or Number groups. Each of these groups on the ribbon has a small icon in the bottom-right corner that when clicked, opens the Format Cells dialog box where you can customize the formatting for your cells in greater detail.
To accept or reject changes in a Microsoft Word document, you would click on the Review tab above the tools ribbon and then you can manage changes and track them accordingly.
If you're downloading a table in Excel, to do so as an XLS file, you should select the file format, and then choose the location on your computer where you want the file to be saved.
