VBA自定义函数"=hztopy（）"下面是一个VBA自定义函数，工具->宏->Visual Basic编辑器->，插入模块,在VBA编辑器里面->插入->模块->贴入下述代码，那么，比如在A3中有"进退两难"，则在B3中输入"=hztopy（A3）"，则会得到"JTLN"。
不过此法有时候也会出错，比如"皓、鑫、婷、雯、奕"等，就无法提取汉字拼音首字母。

比如在A2中有"进退两难"，则在B2中输入如下函数"=LOOKUP()"，则会得到"JTLN"。
提取前四个字首字母时的函数=LOOKUP(CODE(A2),45217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154 ,5397,5405,5689,6170,6229,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J"," K","L","M","N","O","P","Q","R","S","T","W","X","Y","Z"})&LOOKUP(CODE(MID(A2,2,1)),4 5217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154,5397,5405,5689,6170,62 29,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J","K","L","M","N","O","P", "Q","R","S","T","W","X","Y","Z"})&LOOKUP(CODE(MID(A2,3,1)),45217+{0,36,544,1101,16 09,1793,2080,2560,2902,3845,4107,4679,5154,5397,5405,5689,6170,6229,7001,7481,7763,8472, 9264},{"A","B","C","D","E","F","G","H","J","K","L","M","N","O","P","Q","R","S","T","W","X ","Y","Z"})&LOOKUP(CODE(MID(A2,4,1)),45217+{0,36,544,1101,1609,1793,2080,2560,2902 ,3845,4107,4679,5154,5397,5405,5689,6170,6229,7001,7481,7763,8472,9264},{"A","B","C","D" ,"E","F","G","H","J","K","L","M","N","O","P","Q","R","S","T","W","X","Y","Z"})提取前二个字首字母时的函数=LOOKUP(CODE(A2),45217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154 ,5397,5405,5689,6170,6229,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J"," K","L","M","N","O","P","Q","R","S","T","W","X","Y","Z"})&LOOKUP(CODE(MID(A2,2,1)),4 5217+{0,36,544,1101,1609,1793,2080,2560,2902,3845,4107,4679,5154,5397,5405,5689,6170,62 29,7001,7481,7763,8472,9264},{"A","B","C","D","E","F","G","H","J","K","L","M","N","O","P", "Q","R","S","T","W","X","Y","Z"})想提取前一个字、前三个字首字母应该怎么办你自己想想吧不过此法也存在方法三的问题。
