这个问题困扰了我很长时间，今天终于找到答案了。把方法发一下希望对大家有用。
在EXECL中 ，按ALT+F11，插入---模块   复制下列代码 ：
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

比如在A1输入  阿奇霉素   则在其他空白单元格输入  =hztopy(A1)    回车执行即可.
