hello,

i´m looking for a solution for this problem (with 7 cols) for excel 2003. One problem: the lists in the columns sometimes have empty cells in between.

Hope you can help...

Thank you

Harold

Hello Harold!

I think that would require vba. Post your question in a forum like https://www.excelforum.com/. I am sure they can help you.

Thank you for your comment!

/Oscar

I need to improve my vba skills...

Harold,

Maybe this blog post can help you?

Dear, Oscar,

I have a two ranges/lists. How to extract the same values from other range contained in two ranges (without VBA)?

Can you help?

Rita,

unique-distinct-and-common-values-from-two-ranges.xls

That is what I wanted.

Thanks for your quick reply, Oscar!

Rita.

Oscar,

Could you modify you formula to use it with criterion?

e.g. - criterion for GG and II from your reply is QWERTY in A:A column, bun in B:B are other criteria in coincidence with one II.

Can you help?

Rita,

I am not sure I understand. Can you provide an example and desired outcome?

UNIQUE DISTINCT AND COMMON VALUES FROM TWO RANGES USING CRITERION

CRITERIA List1 CRITERIA List2 Common values with criterion:

for for

list 1 list2

other AA QWERTY GG GG

other BB other HH JJ

other CC other II #error!

QWERTY GG QWERTY JJ

other EE other KK

other FF other LL

other GG other MM

other HH other YY

QWERTY II other OO

QWERTY JJ other PP

Thank's.

Ohh, sorry!

Another stucture when posting.

Rita,

See attached file:

unique-distinct-and-common-values-from-two-ranges.xlsx

Not exactly, Oscar.

Because the G:G range didn't exclude HH value (HH="other").

What I want it so that the G:G range only have a values with QWERTY criterion.

Thanks anyway.

But you're still help me?

Rita,

See attached file:

unique-distinct-and-common-values-from-two-ranges1.xlsx

Yes, thank you, Oscar!

Hi, Oscar!

If we replace this part *(COUNTIF($J$1,$A$2:$A$11)>0) of the formula by *(IF($J$1=$D$2:$D$11,ROW($E$2:$E$11))), formula will work more correctly with big ranges.

Oscar, I need your help.

How to modify this formula - {INDEX($E$2:$E$11,MATCH(0,COUNTIF($G$1:G1,$E$2:$E$11)+COUNTIF($B$2:$B$11,$E$2:$E$11),0))} that it works with criterion "OTHER" from your last attached example file? I need values from List2 with "other" criterion are not in List1 with "other" criterion.

The rusult is II. Because in List2 II with "other" criterion, but in List1 II with "QWERTY" criterion, that's what I want - II.

Can you help?

Rita,

Your question is really interesting! But I have no answer! That makes it even more interesting.

Thanks anyway, Oscar.

Hi Oscar,

I am really amazed to see your examples in the thread "Extract a unique distinct list from three columns with possible blanks". However, Do you have the working example file for excel 2003 version?

Hi Oscar,

I modified your formula to work on my spreadsheet, but somehow it is giving blank cells. Maybe because it is in error.

I work in Office 2013:

=IFERROR(IFERROR(INDEX(List1;MATCH(0;IF(ISBLANK(List1);1;COUNTIF($A$11:A11;List1));0));INDEX(List2;MATCH(0;IF(ISBLANK(List2);1;COUNTIF($A$11:A11;List2));0)));"")

Your help will be highly appreciated :)

Hi !

I have tried several of these formulas, works great, but if I hit the formula bar, and hit enter it doesn't work anymore. I have also seen that there are { in front of the formula, and } after. Any clue ?

In order to execute the command you need to hit CTRL + Shift + Enter. If the formula is formatted correctly it will put the curly {} around the formula

Hi, I have been trying to use your formula to get a list of distinct years from date columns in various tables however it doesn't seem to work if a table contains only 1 row? See formula below with 1 of my table columns included:

=IFERROR(IFERROR(IFERROR(INDEX(YEAR(tblLeakTest[Date]), MATCH(0, COUNTIF($E$1:E1, YEAR(tblLeakTest[Date]))+(YEAR(tblLeakTest[Date])=""), 0)), INDEX(YEAR($B$2:$B$7), MATCH(0, COUNTIF($E$1:E1, YEAR($B$2:$B$7))+(YEAR($B$2:$B$7)=""), 0))), INDEX(YEAR($C$2:$C$12), MATCH(0, COUNTIF($E$1:E1, YEAR($C$2:$C$12))+(YEAR($C$2:$C$12)=""), 0))), "")
