1.啟動Excel 2003（其它版本請仿照操作），打開相應的工作表；
2.執行“工具→宏→Visual Basic編輯器”命令（或者直接按“Alt+F11”組合鍵），進入Visual Basic編輯狀態；
3.執行“插入→模塊”命令，插入一個新模塊。再雙擊插入的模塊，進入模塊代碼編輯狀態；
4.將代碼輸入其中；
Function pinyin(p As String) As String
i = Asc(p)
Select Case i
Case -20319 To -20284: pinyin = "A"
Case -20283 To -19776: pinyin = "B"
Case -19775 To -19219: pinyin = "C"
Case -19218 To -18711: pinyin = "D"
Case -18710 To -18527: pinyin = "E"
Case -18526 To -18240: pinyin = "F"
Case -18239 To -17923: pinyin = "G"
Case -17922 To -17418: pinyin = "H"
Case -17417 To -16475: pinyin = "J"
Case -16474 To -16213: pinyin = "K"
Case -16212 To -15641: pinyin = "L"
Case -15640 To -15166: pinyin = "M"
Case -15165 To -14923: pinyin = "N"
Case -14922 To -14915: pinyin = "O"
Case -14914 To -14631: pinyin = "P"
Case -14630 To -14150: pinyin = "Q"
Case -14149 To -14091: pinyin = "R"
Case -14090 To -13319: pinyin = "S"
Case -13318 To -12839: pinyin = "T"
Case -12838 To -12557: pinyin = "W"
Case -12556 To -11848: pinyin = "X"
Case -11847 To -11056: pinyin = "Y"
Case -11055 To -2050: pinyin = "Z"
Case Else: pinyin = p
End Select
End Function
Function getpy(str)
For i = 1 To Len(str)
getpy = getpy & pinyin(Mid(str, i, 1))
Next i
End Function
5.代碼輸入完成后，關閉Visual Basic編輯窗口，返回Excel編輯狀態；
6.自定義函數就可以用了，如：選中A2單元格，輸入公式：=getpy(A2)。
