Delete ALL custom cell styles EXCEL

Question

Is it possible to delete ALL the custom/created cell styles in a workbook ? Just leaving the default styles.

Without having to delete them all one by one

Answer 1

Try this small VBA macro:

Sub StyleKiller()
    Dim N As Long, i As Long

    With ActiveWorkbook
        N = .Styles.Count
        For i = N To 1 Step -1
            If Not .Styles(i).BuiltIn Then .Styles(i).Delete
        Next i
    End With
End Sub

This resolves the Builtin vs Custom issue. Note we run the loop backwards to avoid corrupting the loop index.

Answer 2

To simply remove all without using INDEX, try the below:

Sub StyleKiller()
    Dim st As Style
    On Error Resume Next
    For Each st In ActiveWorkbook.Styles
      If Not st.BuiltIn Then
        st.Delete
      End If
    Next
    On Error GoTo 0
End Sub

Answer 3

Ok, this wasn't as hard to do as I first thought.

Bit messy as I don't often use vba; but this code will roll back to just the default styles:

Sub DefaultStyles()
   Dim MyBook As Workbook
   Dim tempBook As Workbook
   Dim CurStyle As Style
   Set MyBook = ActiveWorkbook
   On Error Resume Next
   For Each CurStyle In MyBook.Styles
      Select Case CurStyle.Name
         Case "20% - Accent1", "20% - Accent2", _
               "20% - Accent3", "20% - Accent4", "20% - Accent5", "20% - Accent6", _
               "40% - Accent1", "40% - Accent2", "40% - Accent3", "40% - Accent4", _
               "40% - Accent5", "40% - Accent6", "60% - Accent1", "60% - Accent2", _
               "60% - Accent3", "60% - Accent4", "60% - Accent5", "60% - Accent6", _
               "Accent1", "Accent2", "Accent3", "Accent4", "Accent5", "Accent6", _
               "Bad", "Calculation", "Check Cell", "Comma", "Comma [0]", "Currency", _
               "Currency [0]", "Explanatory Text", "Good", "Heading 1", "Heading 2", _
               "Heading 3", "Heading 4", "Input", "Linked Cell", "Neutral", "Normal", _
               "Note", "Output", "Percent", "Title", "Total", "Warning Text"
         Case Else
            CurStyle.Delete
      End Select
   Next CurStyle
   Set tempBook = Workbooks.Add
   Application.DisplayAlerts = False
   MyBook.Styles.Merge Workbook:=tempBook
   Application.DisplayAlerts = True
   tempBook.Close
End Sub
