Excel查找最后两个下划线之间的文本

Question

我需要一个excel公式来查找excel单元格中最后两个下划线之间的文本:

即

AAA_BBB_CCC_DDDD_E => DDDD
AAA_BBB_CCC_DDD_EEE_E => EEE
AAA_BBB_CCC_DDD_EEE_F_ => F
AAA_BBB_CCC_DDD_EE_GGGGGGGGGG => EE
AAA_BBB_CCC_DDD_EEE_FFF_GGGGGGGGGGGG_H => GGGGGGGGGGGG

我得到的公式是基于最后一个指数: EXCEL LAST INDEX OF

=RIGHT(LEFT(A2,SEARCH("@",SUBSTITUTE(A2,"_","@",LEN(A2)-LEN(SUBSTITUTE(A2,"_",""))))-1),LEN(LEFT(A2,SEARCH("@",SUBSTITUTE(A2,"_","@",LEN(A2)-LEN(SUBSTITUTE(A2,"_",""))))-1))-SEARCH("@",SUBSTITUTE(LEFT(A2,SEARCH("@",SUBSTITUTE(A2,"_","@",LEN(A2)-LEN(SUBSTITUTE(A2,"_",""))))-1),"_","@",LEN(LEFT(A2,SEARCH("@",SUBSTITUTE(A2,"_","@",LEN(A2)-LEN(SUBSTITUTE(A2,"_",""))))-1))-LEN(SUBSTITUTE(LEFT(A2,SEARCH("@",SUBSTITUTE(A2,"_","@",LEN(A2)-LEN(SUBSTITUTE(A2,"_",""))))-1),"_","")))))

我需要让这个不那么复杂,任何想法？

Answer 1

试试这个

=TRIM(LEFT(RIGHT(SUBSTITUTE(H3,"_",REPT(" ",100)),200),100))

请注意,如果任何段可能超过50个字符,请相应地增加100和200个数字
