1、新建一个Excel文件，输入示例汉字内容。
1、【文件】->【选项】->【自定义功能区】->【主选项卡】->勾选【开发工具】
点击确定以后，导航菜单里增加一项【开发工具】
1、打开【开发工具】菜单，点击第一个【Visual Basic】,弹出代码窗口，
在窗口左侧空白处，点击右键，选择【插入】->【模块】。窗口右侧出现一个白色背景框。
复制粘贴如下内容到右侧框中（虚线之间的内容，不含虚线）：
---------------------------------------------------------------------
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 >= 53679 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
'逐个取ASC码
Function getpy(str)
For i = 1 To Len(str)
getpy = getpy & getpychar(Mid(str, i, 1))
Next i
End Function

2、点击菜单中【保存】，弹出一个提示框，点【是】，再次弹出一个提示框，点【确定】。
1、关闭代码窗口，回到Excel文件。鼠标定位到“拼音首字母”列第一行（C2单元格）。
在函数框中输入=getpy(B2)，（调用自定义函数，获取B2单元格中汉字内容首字母）回车，可以看到获取到B2单元格中内容的首字母。
1、鼠标定位到单元格C2右下角，光标变成黑色十字，按住鼠标左键往下拉至C15行。获取全部内容的首字母。
