问题
I am using a trim formula in excel:
TRIM(LEFT(SUBSTITUTE(MID(M2,FIND("|",SUBSTITUTE(M2,"-","|",2))+1,LEN(M2)),"-",REPT(" ",LEN(M2))),LEN(M2)))
this looks for a number in between a string of 4 numbers:
193449542-27309370502-9045796-169794419204
which works perfectly.
I want to add an if= when a another cell on that same row contains either "bing" or "Adwords" and skip cells that contain it.
回答1:
In H2 per the supplied image,
=IF(NOT(SUM(COUNTIF(J2, "*"&{"bing","Adwords"}&"*"))), TRIM(LEFT(SUBSTITUTE(MID(M2,FIND("|",SUBSTITUTE(M2,"-","|",2))+1,LEN(M2)),"-",REPT(" ",LEN(M2))),LEN(M2))), "")
To add a condition where M2 must contain at least three hyphens, use AND and subtract the length of substituting the hyphens with "" (subtrahend) from the length of the original (minuend). If the result (difference) is 3 or more then there are at least three hyphens.
=IF(and((len(m2)-len(substitute(m2, "-", "")))>=3,NOT(SUM(COUNTIF(J2, "*"&{"bing","Adwords"}&"*")))), TRIM(LEFT(SUBSTITUTE(MID(M2,FIND("|",SUBSTITUTE(M2,"-","|",2))+1,LEN(M2)),"-",REPT(" ",LEN(M2))),LEN(M2))), "")
