如果两个单元格包含相同的根URL，则删除行

Question

I have a two column spreadsheet.

In Column AI have one URL in Column BI have another URL.

I want to delete the entire row if both cells in the same row contain the same root domain.

Example:

Delete the following

Cell A1 = www.google.com 
Cell B1 = www.google.com/randomsubpage/anothersubpage

Keep the following

Cell A1 = www.yahoo.com/randomsubpage/anothersubpage
Cell B1 = www.google.com/randomsubpage/anothersubpage

Is this possible? If it's possible outside of Excel, I'm also open to suggestions.

Thanks,

Sam

Answer 1

1. Place this formula in cell C1

   =IF(LEFT(A1,FIND(".com",A1)+3)=LEFT(B1,FIND(".com",B1)+3),"Delete","")

2. Drag down the length of your data set.

3. Filter on Column C for Delete

4. Delete the filtered rows.

This assumes all your urls are ".com". If you have ".net" or ".gov" or whatever, as well, you'll need to find a more common string to lookup in the FIND function and adjust the positioning accordingly.

This formula will work for multiple url endings:

=IF(LEFT(A1,FIND(".",A1,FIND(".",A1)+1)+3)=LEFT(B1,FIND(".",B1,FIND(".",B1)+1)+3),"DELETE","")

Answer 2

I thought I should try and make it cope with http:// or https:// and possibly subdomains and domains like .tv but maybe I'm over-thinking it! Not sure whether www should be considered part of the URL, but haven't put that in at present:-

=LEFT(SUBSTITUTE(SUBSTITUTE(A1,"http://",""),"https://","")&"/",FIND("/",SUBSTITUTE(SUBSTITUTE(A1,"http://",""),"https://","")&"/"))
=LEFT(SUBSTITUTE(SUBSTITUTE(B1,"http://",""),"https://","")&"/",FIND("/",SUBSTITUTE(SUBSTITUTE(B1,"http://",""),"https://","")&"/"))
