操作方法
打开Excle，新建一个文件，在第A1列中输入姓名。
在B1列中输入如下公式： =VLOOKUP(A1,{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2) 回车确定后，B1列中就出现了首字母。怎么只有一个？别急，还有下一步。
在B1公式最后面接着输入： &VLOOKUP(MID(A1,2,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2) 回车确定后，B1列中就出现了2个首字母。怎么只有2个？别急，往下看。
如果想出现更多的首字母，那么就在后面继续输入类似上面的内容。以下给出的是能同时提取10个首字母公式代码。 =VLOOKUP(A1,{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,2,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,3,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,4,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,5,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,6,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,7,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,8,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,9,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)&VLOOKUP(MID(A1,10,1),{"","";"吖","A";"八","B";"嚓","C";"咑","D";"鵽","E";"发","F";"猤","G";"铪","H";"夻","J";"咔","K";"垃","L";"嘸","M";"旀","N";"噢","O";"妑","P";"七","Q";"囕","R";"仨","S";"他","T";"屲","W";"夕","X";"丫","Y";"帀","Z"},2)
拉动B1单元格右下角的填充柄向下填充，就可以得到所有的首字母了。
