What does dialog box launcher in excel do?

A dialog box launcher in Excel is a small arrow icon typically found in the corner of some groups on the Ribbon. When clicked, it opens a dialog box that provides more detailed options and settings related to that group, allowing users to customize their tasks more thoroughly. For example, in the Home tab, the dialog box launcher in the Font group opens the Format Cells dialog, where users can adjust font styles, sizes, and other formatting options.
