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

ElseIf (tmp >= 45253 And tmp <= 45760) Then
