How do I delete all buttons on a worksheet?

See code below :)

Sub RemoveButtons()
Dim i As Integer
    If ActiveSheet.ProtectContents = True Then
        MsgBox "The Current Workbook or the Worksheets which it contains are protected." & vbLf & "                          Please resolve these issues and try again."
    End If

    On Error Resume Next
        ActiveSheet.Buttons.Delete
End Sub

or could you use code below: (Buttons in VBA are in the Shapes collection).

Sub DelButtons()
Dim btn As Shape

For Each btn In ActiveSheet.Shapes
    If btn.AutoShapeType = msoShapeStyleMixed Then btn.Delete
Next

End Sub

source: Deleting a collections of VBA buttons

See the code below:

Sub DeleteAllShapes() 

    ActiveSheet.Shapes.SelectAll

    Selection.Delete

End Sub

If somebody found this question, but needs to delete only one button, this helped me:

ActiveSheet.Shapes("my_button_name").Delete
