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。代碼如下：

Function pinyin(p As String) As Stringi = Asc(p)Select Case iCase -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 = pEnd SelectEnd Function

Function getpy(str)For i = 1 To Len(str)getpy = getpy & pinyin(Mid(str, i, 1))Next iEnd 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)
