In cell A1, enter âSome text,â and then press Enter. Click Record Macro. In the Record Macro dialog box, type a name for the macro in the Macro name box. For example, type BoldMe.

This is the most important step, because if you don't already have a Personal Macro Workbook, Excel will create one for you. Click in cell A1 and press Ctrl+B to apply bold formatting. Thatâs the only step in the macro. Click Developer > Stop Recording.
