excel：汉字拼音首字母提取

方法一：VBA自定义函数"=hztopy（）"
下面是一个VBA自定义函数，工具->宏->Visual Basic编辑器->，插入模块,在VBA编辑器里面->插入->模块->贴入下述代码，（按ALT＋F11，插入模块，在右面窗口中粘贴下面代码）那么，比如在A3中有"进退两难"，则在B3中输入"=hztopy（A3）"，则会得到"JTLN"。

不过此法有时候也会出错，比如"皓、鑫、婷、雯、奕"等，就无法提取汉字拼音首字母。

Function hztopy(hzpy As String) As String
Dim hzstring As String, pystring As String
Dim hzpysum As Integer, hzi As Integer, hzpyhex As Integer
hzstring = Trim(hzpy)
hzpysum = Len(Trim(hzstring))
pystring = ""
For hzi = 1 To hzpysum
hzpyhex = "&H" + Hex(Asc(Mid(hzstring, hzi, 1)))
Select Case hzpyhex
Case &HB0A1 To &HB0C4: pystring = pystring + "A"
Case &HB0C5 To &HB2C0: pystring = pystring + "B"
Case &HB2C1 To &HB4ED: pystring = pystring + "C"
Case &HB4EE To &HB6E9: pystring = pystring + "D"
Case &HB6EA To &HB7A1: pystring = pystring + "E"
Case &HB7A2 To &HB8C0: pystring = pystring + "F"
Case &HB8C1 To &HB9FD: pystring = pystring + "G"
Case &HB9FE To &HBBF6: pystring = pystring + "H"
Case &HBBF7 To &HBFA5: pystring = pystring + "J"
Case &HBFA6 To &HC0AB: pystring = pystring + "K"
Case &HC0AC To &HC2E7: pystring = pystring + "L"
Case &HC2E8 To &HC4C2: pystring = pystring + "M"
Case &HC4C3 To &HC5B5: pystring = pystring + "N"
Case &HC5B6 To &HC5BD: pystring = pystring + "O"
Case &HC5BE To &HC6D9: pystring = pystring + "P"
Case &HC6DA To &HC8BA: pystring = pystring + "Q"
Case &HC8BB To &HC8F5: pystring = pystring + "R"
Case &HC8F6 To &HCBF9: pystring = pystring + "S"
Case &HCBFA To &HCDD9: pystring = pystring + "T"
Case &HEDC5: pystring = pystring + "T"
Case &HCDDA To &HCEF3: pystring = pystring + "W"
Case &HCEF4 To &HD1B8: pystring = pystring + "X"
Case &HD1B9 To &HD4D0: pystring = pystring + "Y"
Case &HD4D1 To &HD7F9: pystring = pystring + "Z"
Case Else
pystring = pystring + Mid(hzstring, hzi, 1)
End Select
Next
hztopy = pystring
End Function
方法二：VBA自定义函数"=getpy()"
下面是一个VBA自定义函数，工具->宏->Visual Basic编辑器->，插入模块,在VBA编辑器里面->插入->模块->贴入上述代码，那么。

那么，比如在A2中有"进退两难"，则在B2中输入"=getpy(A2)"，则会得到"JTLN"。

不过此法有时候也会出错，比如"鑫、雯、奕"等，就无法提取汉字拼音首字母，还有些字如"皓、婷"等被错提取为“Z”。

Function getpychar(char)
tmp = 65536 + Asc(char)
If (tmp >= 45217 And tmp <= 45252) Then
getpychar = "A"
ElseIf (tmp >= 45253 And tmp <= 45760) Then
getpychar = "B"
ElseIf (tmp >= 45761 And tmp <= 46317) Then
getpychar = "C"
ElseIf (tmp >= 46318 And tmp <= 46825) Then
getpychar = "D"
ElseIf (tmp >= 46826 And tmp <= 47009) Then
getpychar = "E"
ElseIf (tmp >= 47010 And tmp <= 47296) Then
getpychar = "F"
ElseIf (tmp >= 47297 And tmp <= 47613) Then
getpychar = "G"
ElseIf (tmp >= 47614 And tmp <= 48118) Then
getpychar = "H"
ElseIf (tmp >= 48119 And tmp <= 49061) Then
getpychar = "J"
ElseIf (tmp >= 49062 And tmp <= 49323) Then
getpychar = "K"
ElseIf (tmp >= 49324 And tmp <= 49895) Then
getpychar = "L"
ElseIf (tmp >= 49896 And tmp <= 50370) Then
getpychar = "M"
ElseIf (tmp >= 50371 And tmp <= 50613) Then
getpychar = "N"
ElseIf (tmp >= 50614 And tmp <= 50621) Then
getpychar = "O"
ElseIf (tmp >= 50622 And tmp <= 50905) Then
getpychar = "P"
ElseIf (tmp >= 50906 And tmp <= 51386) Then
getpychar = "Q"
ElseIf (tmp >= 51387 And tmp <= 51445) Then
getpychar = "R"
ElseIf (tmp >= 51446 And tmp <= 52217) Then
getpychar = "S"
ElseIf (tmp >= 52218 And tmp <= 52697) Then
getpychar = "T"
ElseIf (tmp >= 52698 And tmp <= 52979) Then
getpychar = "W"
ElseIf (tmp >= 52980 And tmp <= 53640) Then
getpychar = "X"
ElseIf (tmp >= 53689 And tmp <= 54480) Then
getpychar = "Y"
ElseIf (tmp >= 54481 And tmp <= 62289) Then
getpychar = "Z"
Else '如果不是中文，则不处理
getpychar = char
End If
End Function
Function getpy(str)
For i = 1 To Len(str)
getpy = getpy & getpychar(Mid(str, i, 1))
Next i
End Function
方法三：Excel函数LOOKUP
这个函数在Excel里面最多只能设置自动提取字段的前四个字的拼音首字母，多了会提示公式太长。

比如在A2中有"进退两难"，则在B2中输入如下函数"=LOOKUP()"，则会得到"JTLN"。

=LOOKUP(CODE(A2),45217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154 ,5397,5405,5689,6170,6229,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J"," K","L","M","N","O","P","Q","R","S","T","W","X","Y","Z"})&LOOKUP(CODE(MID(A2,2,1)),4 5217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154,5397,5405,5689,6170,62 29,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J","K","L","M","N","O","P", "Q","R","S","T","W","X","Y","Z"})&LOOKUP(CODE(MID(A2,3,1)),45217+{0,36,544,1101,16 09,1793,2080,2560,2902,3845,4107,4679,5154,5397,5405,5689,6170,6229,7001,7481,7763,8472, 9264},{"A","B","C","D","E","F","G","H","J","K","L","M","N","O","P","Q","R","S","T","W","X ","Y","Z"})&LOOKUP(CODE(MID(A2,4,1)),45217+{0,36,544,1101,1609,1793,2080,2560,2902 ,3845,4107,4679,5154,5397,5405,5689,6170,6229,7001,7481,7763,8472,9264},{"A","B","C","D" ,"E","F","G","H","J","K","L","M","N","O","P","Q","R","S","T","W","X","Y","Z"})
提取前二个字首字母时的函数
=LOOKUP(CODE(A2),45217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154 ,5397,5405,5689,6170,6229,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J"," K","L","M","N","O","P","Q","R","S","T","W","X","Y","Z"})&LOOKUP(CODE(MID(A2,2,1)),4 5217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154,5397,5405,5689,6170,62 29,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J","K","L","M","N","O","P", "Q","R","S","T","W","X","Y","Z"})
想提取前一个字、前三个字首字母应该怎么办你自己想想吧
不过此法也存在方法三的问题。
