    Date Formula Question_Follow-up for dates falling on same weekly cut-off

    I don't think you really understood my point. I am very well aware of the German 'z' (you know very well that I am fluent in German). I can see nothing offensive here, intended or otherwise. I am pretty certain that this is the member's real name. My reaction has nothing to do with leniency or...

    Date Formula Question_Follow-up for dates falling on same weekly cut-off

    NAZI is only a part of the user name. It is quite possible that this member has a real name that begins with Naz and is habitually shortened to Nazie. Furthermore, the 'z' may not be pronounced 'ts', but as an Anglicised 'z'. I think your reaction is most probably over-sensitive.

    Look up Unique item Value if Criteria

    By the way, I am not a Sir - do I really look like a man??? Try this: =IFERROR(FILTER(Data!$I$4:$J$10001,(LEFT(Data!$A$3:$A$10000,20)=LEFT(C18,20))*(Data!$G$4:$G$10001=B18)),"")

    Please provide a desensitised sample workbook. Which version of Excel is this for?

    Any chance you could explain your requirement in plain English? What happened when you tried to adapt the formula I gave you? Please don't drip feed your requirements.

    Can't answer that. then? ;) In E18 copied down: =IFERROR(FILTER(Data!$I$4:$J$10001,(Data!$A$3:$A$10000=C18)*(Data!$G$4:$G$10001=B18)),"")

    Lookup from multiple worksheets and return result

    They could do, but it would require a rethink of the results layout. I have set the formula to use the first of the two. (TAKE). At no point has the OP made it clear that both results should be shown (they have been very unwilling to properly clarify the expected results throughout, which has...

    The formula doesn't use a named range - the ranges are defined within the formula. It's not a half measure. :confused: Glad to have helped. :)

    OK - I am looking at your workbook. What is the likelihood of ANY of the month sheets having one million rows of data?

    Lookup from multiple worksheets and return result

    You need to create a sample workbook using some of the data from the real workbook, but desensitised. Remove data from columns that are not needed in the formula. The sample workbook needs to show the problem.

    Lookup from multiple worksheets and return result

    I can't troubleshoot a workbook I have no access to. I can't troubleshoot from screenshots. Where it returns "Not Found", there is no match. Provide a workbook with that error and I'll see if I can tell you why, but if there is no exact match, then it's your data that isn't consistent. As I...

    You need to take more care. You have messed up the end of the formula. Look: =LET(reg,VSTACK(start:finish!K2:K100), date,VSTACK(start:finish!M2:M100), sum_insured,VSTACK(start:finish!U2:U100), DROP(REDUCE("",TOCOL(A3:A1000000,1),LAMBDA(x,y...

    Why do you keep on repeating this? We understand what you are trying to avoid, and my solution should (and hopefully will) make this unnecessary.

    The attachment does not contain my formula, so I have no way of checking it for you. In what way is it NOT doing what you want? One guess: =LET(reg,VSTACK(start:finish!K2:K100), date,VSTACK(start:finish!M2:M100), sum_insured,VSTACK(start:finish!U2:U100)...

    I think this works. Remove ALL expected results from C3 onwards, then in C3 followed by ENTER: =LET(reg,VSTACK(start:finish!K2:K100), date,VSTACK(start:finish!M2:M100), sum_insured,VSTACK(start:finish!U2:U100), DROP(REDUCE("",TOCOL(A3:A100,1),LAMBDA(x,y...

    Lookup from multiple worksheets and return result

    This uses column C instead: =MAP(A3:A17,B3:B17, LAMBDA(x,y, LET(s,LOWER(C3), k,INDIRECT("'"&s&"'!K:K"), u,INDIRECT("'"&s&"'!U:U"), XLOOKUP(x,k,u,"")))) It returns no matches in June. It's not my job to work out why matches aren't happening - that's up to you.

    Lookup from multiple worksheets and return result

    I have standardised your tab names as mmmyyyy. This in F3: =MAP(A3:A17,B3:B17, LAMBDA(x,y, LET(s,SUBSTITUTE(LOWER(y),"-","20"), k,INDIRECT("'"&s&"'!K:K"), u,INDIRECT("'"&s&"'!U:U"), XLOOKUP(x,k,u,"")))) You have a couple of rows that don't match - check for leading and trailing spaces there.

    How do I do the opposite of FILTER formula in Cell L2? [SOLVED]

    Building on what @Peter Bartholomew has already done, this in L3 copied down: =LET(n, QUOTIENT(COUNTA(GridPointTbl[@]), 2), k, SEQUENCE(n, 2), list, INDEX(GridPointTbl[@], k), distinct, UNIQUE(list), unique, UNIQUE(list, , 1), na, ROWS(distinct), nb, ROWS(unique), r, {1,1} * SEQUENCE(na + nb)...
