I see no issue with your formula (tested in an example workbook).  What seems to be the problem?

Your formulas in the workbook are using the TRUE argument in the VLOOKUP instead of FALSE.  They're also looking for 100 columns across; should just be 1.  Your example was correct.

They should be:
[Test1] sheet, B2:  =IF(ISNA(VLOOKUP(A2,TEST2!$A$2:$A$70000,1,FALSE)),"NO","YES")
[Test2] sheet, B2:  =IF(ISNA(VLOOKUP(A2,TEST1!$A$2:$A$70000,1,FALSE)),"NO","YES")

You may also use the following functions to get the desired output...

On Test1,
In B2
=IF(ISNUMBER(MATCH(A2,TEST2!A:A,0)),"Yes","No")

Open in new window


On Test2,
In B2
=IF(ISNUMBER(MATCH(A2,TEST1!A:A,0)),"Yes","No")

Open in new window

^Those work.  So do these:

[Test1] sheet, B2:  =IF(COUNTIF(TEST2!$A$2:$A$70000,A2)>0,"YES","NO")
[Test2] sheet, B2:  =IF(COUNTIF(TEST1!$A$2:$A$70000,A2)>0,"YES","NO")

But it's also important for the requester to understand why the formalas didn't work.

@Glenn
The advantage of Match over Countif is, in Match you can reference the whole columns and the formula will not be evaluated for the whole columns and will stop once it finds the first occurrence of lookup value. So it will be comparatively faster than countif.

If you want to see the comparison side-by-side, you could also add a column to both sheets and create a pivot table which points out the differences.  See attached,  Just a thought...
