如何提取汉语拼音的首字？一般来说，有两种方法！

　　①函数法：利用vlookup，但有一定的局限性，效率也是问题。

　　②vba法：是最佳的选择，并且，仅使用几行Excel VBA代码就行，为什么这么说呢？因为Excel里利用Vlookup工作表函数和Evaluate方法可以快捷的计算出结果。

　　通过如下例子可以看出Excel VBA独有的优势。代码如下

　　Public Function MyPY(ByVal vText As Variant) As String
　　Application.Volatile
　　Dim strResult As String
　　Dim lStart As Long
　　On Error Resume Next

　　For lStart = 1 To Len(vText)
　　strResult = strResult & Application.Evaluate("VLookup(""" & Mid(vText, _
                                                                         lStart, 1) & _
                                                                         """,　　{""吖"",""A"";""八"",""B"";""嚓"",""C"";""咑"",""D"";""鵽"",""E"";""发"",""F"";""猤"",""G"";& _
""铪"",""H"";""夻"",""J"";""咔"",""K"";""垃"",""L"";""嘸"",""M"";""旀"",""N"";""噢"",""O"";&_
""妑"",""P"";""七"",""Q"";""囕"",""R"";""仨"",""S"";""他"",""T"";""屲"",""W"";""夕"",""X"";& _"
"丫"",""Y"";""帀"",""Z""},2,1)")
     Next

　　MyPY = strResult

　　End Function

　　上文自定义函数提取的是纯汉字，但“中华人民共和国123（辽宁）”要求返回“ZHRMGHG（LN）”

“中华人民共和国1-辽宁”返回“ZHRMGHG-LN”怎么办？

　　关键点：

　　①排除A~Z a~z 0~9，就是所有字母和数字。

　　②判断是否为每个提取的字符是否汉字。一般判断为汉字可以利用ASC码值判断，这里我提供另一种方法。

　　整体代码如下：

　　Public Function SuperPY(ByVal vText As Variant) As String

　　Application.Volatile
　　Dim strResult As String
　　Dim lStart As Long
　　Dim sTemp As String
　　On Error Resume Next

　　For lStart = 1 To Len(vText)

　　sTemp = VBA.StrConv(Mid(vText, lStart, 1), vbNarrow)
         If sTemp Like "[!A-Z !a-z !0-9]" Then   '排除什么可以在like表达式中修改
             If Len(sTemp) <> LenB(StrConv(sTemp, vbFromUnicode)) Then

                 strResult = strResult & Application.Evaluate("VLookup(""" & Mid(vText, _
                                                                                 lStart, 1) & _
                                                                                 """,{""吖"",""A"";""八"",""B"";""嚓"",""C"";""咑"",""D"";""鵽"",""E"";""发"",""F"";""猤"",""G"";& _
""铪"",""H"";""夻"",""J"";""咔"",""K"";""垃"",""L"";""嘸"",""M"";""旀"",""N"";""噢"",""O"";""妑"",& _
""P"";""七"",""Q"";""囕"",""R"";""仨"",""S"";""他"",""T"";""屲"",""W"";""夕"",""X"";""丫"",""Y"";""帀"",""Z""},2,1)")

             Else

                 strResult = strResult & Mid(vText, lStart, 1)
             End If
         End If
　　Next

　　SuperPY = strResult

　　End Function
