Superscript and subscript buttons for Excel 2003/2007/2010/2013/2016

Microsoft Office Excel 2003: By default, the add-in adds the new Superscript, Subscript, and Symbol Font buttons on the Formatting toolbar between the Underline and Align Left buttons (see picture). If you wish, you can copy or move them to any toolbar using the toolbar customization mode. If you accidentally delete those buttons, just restart Microsoft Excel to recreate them.

Microsoft Office Excel 2007: The add-in adds the new Superscript, Subscript, and Symbol Font buttons on the Home tab of the ribbon between the Font and Alignment groups. If you wish, you can add them also the Quick Access Toolbar (QAT) manually.

Microsoft Excel 2010, 2013, and 2016: By default, the add-in adds the new Superscript, Subscript, and Symbol Font buttons on the Home tab of the ribbon between the Font and Alignment groups (see picture below). If you wish, you can hide this button group and/or add them to any custom group on the ribbon using the ribbon customization mode or to the Quick Access Toolbar (QAT).


The new buttons do not work when editing text in text boxes and shapes (including texts on Excel charts) from Microsoft Office Excel 2007 to Microsoft Excel 2016 version 1703. However, there are rarely known built-in keyboard shortcuts for superscript and subscript when editing charts and text boxes — they are actually the same as in Microsoft PowerPoint: try the + key of the main keyboard with Ctrl and Ctrl+Shift

Accessing cell formatting during 3D selection makes Microsoft Excel unstable. Therefore these add-in buttons and keyboard shortcuts are disabled if multiple worksheets are selected at the same time. Do not worry, they will be re-enabled when you enter the edit mode!

Undo is possible only for the most recent Superscript / Subscript / Symbol Font operation. It is not possible to undo older changes after using any of the functions provided by this add-in.

Starting from Microsoft Excel 2016 version 1704 (released only for Office 365 subscribers in May 2017), Superscript and Subscript buttons and corresponding keyboard shortcuts of this add-in work without any of these limitations.


If you have enabled multiple input languages and/or keyboard layouts (usually you see the language indicator on the Windows Taskbar in that case), some keyboard shortcuts (e.g. Ctrl+=) may not work on Excel (or in other Office applications). The default key combinations for switching languages and keyboard layouts might be the reason for that. Try disabling those key sequences:
  1. Open text input control panel by pressing Windows+R, typing control.exe input.dll and clicking OK.
  2. If necessary, in the advanced settings, click the link Change language bar hot keys..., which opens the Text Services and Input Languages dialog.
  3. Change the key settings by clicking Change Key Sequence... button and disabling both key sequences there.
If this does not help, consider removing all extra input languages from the text input control panel leaving only the one your are actually using. That will help for sure.


If you are using a non-English version of Excel, you might like to change the button tooltips and context menu texts so that they work properly in your language. This can be achieved simply by editing the file \Program Files (x86)\PanuWorld\ExcelSuperSubToolbar\ExcelSuperSubToolbar.ini with Notepad.

Detailed information about adding new languages can be found in the file itself. For consistency, it is recommended to check the texts related to the Superscript, Subscript, and Symbol Font functions in Microsoft Word and use the same texts in Excel, too.

You can add a language just for your own fun but if you want to help others, you can send your updated ExcelSuperSubToolbar.ini to with a short cover message.

If you do not like to default keyboard shortcuts, you may try to changing them by editing the ExcelSuperSubToolbar.ini, too. Note that only the last character counts in the shortcut string: pressing Ctrl (and possibly Shift, depending on the chosen character) is implied by the add-in.


To remove the buttons from your Microsoft Excel, uninstall the add-in using Add/Remove Programs (Programs and Features) in the Windows Control Panel.
