How to Programmatically Reset a Workbook to Default Styles (247982)

SUMMARY

The following Microsoft Visual Basic for Applications Sub procedure removes all styles in a Microsoft Excel workbook and then adds back the default styles you see in a new workbook. This macro may be helpful for removing extra styles added to a workbook infected by a macro virus.

This macro uses the Workbooks.Add method, which bypasses templates in the startup directories. Because of this, it works correctly even if templates in the startup directories have had extra styles added to them.

Sub RebuildDefaultStyles()

'The purpose of this macro is to remove all styles in the active
'workbook and rebuild the default styles. "Normal" cannot be
'deleted. Therefore the macro does not attempt to delete it.
'It rebuilds the default styles by merging them from a new workbook.

    'Dimension variables.
    Dim MyBook As Workbook
    Dim tempBook As Workbook
    Dim CurStyle As Style
    
    'Set MyBook to the active workbook.
    Set MyBook = ActiveWorkbook
    
    'Delete all the styles in the workbook.
    For Each CurStyle In ActiveWorkbook.Styles
        If CurStyle.Name <> "Normal" Then CurStyle.Delete
    Next CurStyle

    'Open a new workbook.
    Set tempBook = Workbooks.Add
    
    'Disable alerts so you may merge changes to the Normal style
    'from the new workbook.
    Application.DisplayAlerts = False
    
    'Merge styles from the new workbook into the existing workbook.
    MyBook.Styles.Merge Workbook:=tempBook
    
    'Enable alerts.
    Application.DisplayAlerts = True
    
    'Close the new workbook.
    tempBook.Close

End Sub
