Extract only items not on previous list
Suppose you have two lists:
a, b, c, d, e, f, g and a, b, e, g and you want to extract only the items on the first list that are not on the second list. I tried =IF(A1<$B1:$B8,A1) and also {=IF(A1<$B1:$B8,A1)} neither worked, any suggestions? Thanks, Les |
Assuming that Column A contains your first list, and Column B contains
your second list, try... C1: =SUMPRODUCT(--(COUNTIF($B$1:$B$4,$A$1:$A$7)=0)) D1, copied down: =IF(ROWS($D$1:D1)<=$C$1,INDEX($A$1:$A$7,SMALL(IF(C OUNTIF($B$1:$B$4,$A$1:$ A$7)=0,ROW($A$1:$A$7)-ROW($A$1)+1),ROWS($D$1:D1))),"") ....confirmed with CONTROL+SHIFT+ENTER, not just ENTER. Hope this helps!

When I used your formulas a 3 was generated in cell C1 and zeros in D1:D3
Here is the data A1:A3 {a, d, f} B1:B6 {a, b, c, d, e, f} I want the items in B1:B6 that don't appear in A1:A3 Tried to use a Vlookup and If function and it worked but was cumbersome. How about this VBA code solution? Create an outside loop that steps through each item in the long list. Create an inside loop that steps through each item on the short list If there is no match the active cell is printed in an adjacent cell. If there is a match the inside loop terminates and the outside loop increments to the next item on the list. And so it goes until the last item on the long list is checked.

Hi!
The formula works but the example you posted originally is the opposite of the example you just posted. So, just reverse some of the references: =IF(ROWS($D$1:D1)<=$C$1,INDEX($B$1:$B$6,SMALL(IF(C OUNTIF($A$1:$A$3,$B$1:$B$6)=0,ROW($B$1:$B$6)-ROW($A$1)+1),ROWS($D$1:D1))),"") Array entered.

It works fine for me as expected
you can change Dominic's formula to fit that as well but it would be easier if you put a,b,c,d,e,f, in A1:A5 and a,d,f, in B1:B3 then change Dominic's formula in C1 to =SUMPRODUCT(--(COUNTIF($B$1:$B$3,$A$1:$A$6)=0)) and the formula in D1 to =IF(ROWS($D$1:D1)<=$C$1,INDEX($A$1:$A$6,SMALL(IF(C OUNTIF($B$1:$B$3,$A$1:$A$6)=0,ROW($A$1:$A$6)-ROW($A$1)+1),ROWS($D$1:D1))),"") array enter and copy down returns b, c and e if you want to keep your layout change Dominic's formula accordingly -- Regards, Peo Sjoblom (No private emails please) "Leslie Coover" wrote in message news:_xWJe.327$U92.24@okepread06...

Okay so far so good
Now I have the "long" data in sheet 01.0A and the "short" data in sheet 01.0B used basically the same SUMPRODUCT formula in sheet 01.0C and used =IF(ROWS($B$1:B1)<$A$1,INDEX('01.0A'!$A$1:$A$6,SMA LL(IF(COUNTIF('01.0B'!$A$1:$A$2,'01.0A'!$A$1:$A$6) =0,ROW('01.0A'!$A$1:$A$6)-ROW('01.0A'!$A$1)+1),ROWS($B$1:B1))),"") This works allright, but it only lists the id # for each record, I want all the data for the whole record (column A to column D) what do I need to change? Here is an example, if want W3245 peach 358 red W2178 lemmon 548 yellow but I only get W3245 W2178 I know I could concatanate all the data in each record so it fits into just one cell, but is there an easier way?

Or set things up to display the results some other way. The above could also be done using a macro. Probably you should use the macro recorder if you choose this option. --ron |
Thanks Ron, this works good
When there is an id field and an associated name field this method can extract only the records in list 1(columns A and B) that do not appear in list 2 (columns C and D) and then print the result in say columns G and H.

Thanks Domenic, I could not get the results I wanted, it simply displayed
the same id numbers repeatedly, rather than including data in adjacent cells. If I had really huge data sets your method is definitely superior as results can be printed on one worksheet and the "long list" and "short list" can be kept in two other worksheets. I'm sure there is a way to extract data in adjacent cells along with primary key data, but the data sets I am concerned with are not that large so I decided to use Ron's filter method (in this thread). To use that method all the data must be kept on one sheet (there may be a way to use multiple sheets here too--but I do not know it).

Make sure that this part of the formula...
INDEX('01.0A'!$A$1:$A$6 ....is changed to... INDEX('01.0A'!A$1:A$6 Therefore, your formulas should be as follows...
