   Hi Oscar,
   I started with the solution provided here for obtaining values existing only in one of two lists. I know that, for an ordered done job, one should tend use excel in a 'database-like' fashion, with columns as field and rows for data, and so I do.
   Anyway, it happened that I had the necessity to have two lists of data to compare,but they spread horizontally. I also read your solutions for filtering values existing in different ranges, but since I was in a hurry,I adapted the formulas provided here, and wanted to share my solution.Here is the two alternative formulas that do the job in a 'column fashion':
   Let's say we have two list to compare in ranges G1:V1 and G2:V2 respectively. In the result's range, I put the formula:
   ={INDEX($G$1:$V$1;;SMALL(IF(COUNTIF($G$2:$V$2;$G$1:$V$1)=0;MATCH(COLUMN($G$1:$V$1);COLUMN($G$1:$V$1));"");COLUMN(A1)))}
   or, alternatively (thanks to another solution found here):
   ={INDEX($G$1:$V$1; SMALL(IF(ISERROR(MATCH($G$1:$V$1; $G$2:$V$2; 0)); (COLUMN($G$1:$V$1)-MIN(COLUMN($G$1:$V$1))+1); ""); COLUMN(A$1:A$65536)))} . I noticed that, if I use the same size for all three ranges (lists and results), I end up with having some zeroes padding the 2nd result range (Missing data in List 1), whether I use vertical or horizontal lists.
   as you can see from the image I provide here:

   I am wondering how those zeroes appear ?
   I uploaded the example excel file.

     Bruno,

     You are comparing 4 blank cells ($G$2:$V$2) with the values in cell range $G$1:$V$1. Since there are no blank cells the formula returns the blank cells. The INDEX function then returns 0.

     Try this formula in cell G2:
     =INDEX($G$2:$O$2, , SMALL(IF(COUNTIF($G$1:$S$1, $G$2:$O$2)=0, MATCH(COLUMN($G$2:$O$2), COLUMN($G$2:$O$2)), ""), COLUMN(A1)))

   Hi.
   I have excel file:
   code bookname language bookcode id
   1 book1 en 100
   2 book2 fa 101
   3 book1 ar 102
   4 book3 en 103
   5 book2 fa 104
   6 book4 az 105
   ...

   i have want to filter by book & language columns and when two columns are exist, value of id column equal is last row value of code column. for example:
   book2 is true but book1 is not true. so id book1 = 104

   thanks
