如何函数提取A列数据的前三位并取唯一值
如何函数提取A列数据的前三位并取唯一值。(如701有多个只要一个)求大师们帮忙,表示感谢!=UNIQUE(LEFT(A2:A802,3))
2021以上支持。=IFERROR(AGGREGATE(15,2,LEFT($A$2:$A$802,3)/(MATCH(LEFT($A$2:$A$802,3),LEFT($A$2:$A$802,3),)=ROW($1:$801)),ROW(A1)),"")
2013以上支持 我是2007版本 =IFERROR(SMALL(IF(MATCH(LEFT($A$2:$A$802,3),LEFT($A$2:$A$802,3),)=ROW($1:$801),LEFT($A$2:$A$802,3)*1),ROW(A1)),"")
数组公式,三键好麻烦 07 版的 万 金=IFERROR(LEFT(INDEX(A:A,SMALL(IF((COUNTIF(INDIRECT("r1c:r[-1]c",),LEFT($A$2:$A$900,3))=0)*LEN($A$2:$A$900),ROW($2:$900)),1)),3),"") 07,非数组。=LEFT(LOOKUP(1,0/FREQUENCY(1,(COUNTIF(C$1:C1,LEFT(A$2:A802,3))=0)*(A$2:A802<>"")),A$2:A802),3) 非常感谢,好好向大师们学习 =INDEX(LEFT(A$2:A$802,3),SMALL(IF(MATCH(LEFT(A$2:A$802,3),LEFT(A$2:A$802,3),)=ROW($1:$801),ROW($1:$801)),ROW(A1))) 好好向大师们学习,非常感谢! =MIN(--IF(COUNTIF($C$1:C1,LEFT(OFFSET($A$2,,,COUNT(A:A)),3))=0,LEFT(OFFSET($A$2,,,COUNT(A:A)),3),9E+307))
数组三键
