In Excel, how can you format a cell to display currency?

The method of formatting a cell to display currency by right-clicking the cell, selecting "Format Cells," and then choosing "Currency" is the correct approach. This option allows users to access a comprehensive menu for cell formatting, where various formats, including currency, can be chosen.

By selecting "Currency," the user can apply specific options such as decimal points, currency symbols (like the dollar sign), and negative number formatting. This ensures that the data displayed in the cell is not only visually appealing but also in a format that is widely understood as monetary value.

Other options do not provide the appropriate method for currency formatting. The shortcut for copying cells is not relevant to formatting, typing a dollar sign directly does not apply consistent formatting rules, and the "Insert" menu does not include a feature for changing the format of a cell to currency. Thus, the right-click method is the most efficient and effective way to achieve currency formatting in Excel.
