1、进入VBA编辑面板打开Excel，按Ctrl+F11，快速进入VBA编辑面板，初学者可以从开发工具——Visual Basic进入VBA，如图：
3、输入代码输入以下代码：Function MyGet(Srg As String, Optional n As Integer = False)Dim i As IntegerDim s, MyString As StringDim Bol As BooleanFor i = 1 To Len(Srg)s = Mid(Srg, i, 1)If n = 1 ThenBol = Asc(s) < 0ElseIf n = 2 ThenBol = s Like "[a-z,A-Z]"ElseIf n = 0 ThenBol = s Like "#"End IfIf Bol Then MyString = MyString & sNextMyGet = IIf(n = 1 Or n = 2, MyString, Val(MyString))End Function然后保存，如图：
