Superscript letters or numbers appear slightly above normal text in smaller font. Superscript is commonly used when writing mathematical expressions or formulas or in chemistry when identifying isotopes or chemicals and compounds. Although there are no designated superscript or subscript keys on the keyboard, you can use keyboard shortcuts to write them. When creating a spreadsheet in Microsoft Excel, you can use the available superscript button or keyboard shortcuts to write in superscript.
Select the cell or highlight the text you want to designate as superscript.
Click the "Home" tab, and select the "Format Cell Font" button located next to the "Font" title.
Click "Effects," and check the box next to "Superscript."
Press "Ctrl" + "Shift" + "F" or "Ctrl" + 1" to bring up the font tab automatically instead of clicking through to reach it.
