问题
I want to compare values in two columns in Excel as depicted in the image below :-
Using the formula, I want to put the values in the "Values of A which don't exist in B" and "Values of B which don't exist in A". Any help is appreciated.
I have shared the same excel sheet here.
回答1:
The following will work - for each, add the formula in row 2 and then drag down
Values of A that do not exist in B
=IF(ISERROR(MATCH($A$2:$A$20,$B$2:$B$17,0)),A2,"")
Result = x, y, z, i, j ,k, l, u
NB: Your example spreadsheet is incorrect as u is in Col A but not Col B but you do not list it in your result set in Col C
Values of B that do not exist in A
=IF(ISERROR(MATCH($B$2:$B$17,$A$2:$A$20,0)),B2,"")
Result = q, r, e, f, g

You can also do this with Advance Filter Assuming Data in Col A and B In Cell C2 write =SUMPRODUCT(--($B$2:$B$17=A2))=0 Select Data A1:A12 Click on Advanced Filter, Choose copy to another location List Range = $A$1:$A$22 Criteria Range = $C$1:$C$2 (Note C1 to be blank) In Copy to Range choose E1, Say OK This will give you Values of A that don't exist in B
In Cell D2 Write =SUMPRODUCT(--($A$2:$A$22=B2))=0
Select Data B1:B17 Click on Advanced Filter, Choose copy to another location List Range = $A$1:$A$22 Criteria Range = $D$1:$D$2 (Note D1 to be blank) In Copy to Range choose F1, Say OK This will give you Values of B that dont exist in A
You can automate this Via a single line of Code
Sub Get_Data1()
[List1].AdvancedFilter 2, [Crt1], [Dest1], True
End Sub
Sub Get_Data2()
[List2].AdvancedFilter 2, [Crt2], [Dest2], True
End Sub
