Excel中如何用函数实现提取汉字的首字母

实例工具：WPS 2019/OFFICE 2019
有一些场合，要用到汉字的首字母缩写，而Excel中并没有这样一个函数，可以直接提取汉字的首字母。不过拓展性极强大的VBA给提供了无限的可能。
如下，需要H列增加B列的中文首字符

点击进入VBA，在VBE界面中增加一个模块如下


然后关闭这个新界面，返回Excel，就可以像Excel自带的函数一样使用这个自定义的Getpy函数了，它只有一个参数，参数可以直接指定单元格，也可以直接输入字符
如下：


需要注意的是，Getpy函数，只返回汉字拼音的首字母，如果是其他的字母或者数据等非汉字文本，会返回原来的值

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 Else: pinyin = p

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