Advanced sorting/matching

Welcome to the forum.

There are instructions at the top of the page explaining how to attach your sample workbook (yellow banner: HOW TO ATTACH YOUR SAMPLE WORKBOOK). Screenshots are of little practical use as we cannot manipulate them.

A good sample workbook has just 10-20 rows of representative data that has been desensitised. The sample layout accurately matches that of your real data. It also has expected results mocked up, worked examples where required, relevant cells highlighted and a few explanatory notes.

Administrative Note:

Is your forum profile showing the Excel PRODUCT that you need this to work for?

Members will tailor the solutions they offer to the Office PRODUCT (Excel, NOT Windows) that you have. Please check that your forum profile is up-to-date in this respect. If you aren't sure, in Excel go to File | Account and report what it says below the MS logo at the top of that page. If your product is for Mac, please also state this.

The three most recent Excel products are Excel 2019, Excel 2021 and MS365 - if you are using MS365, please give this name along with the version number in your profile (e.g. MS365 Version 2306). This is in the About Excel section further down the Account page.

Thanks.

And your Excel version? Business means NOTHING.

If you have 365 (update your profile, please), paste this into H1 and hit ENTER:

What is the problem with my formula??? Why has it been abandoned?

TMS' formula added to the attached and working perfectly, but it has to be copied down - mine does not.

If you need help adapting mine, just say.

Learning from Ali*. Slightly shorter version that won't need the ranges adjusted.

Formula:

* Thanks for the TOCOL. Finally think I’m getting to grips with DROP/REDUCE

You can do it like this:

Pleae provide a more realistic sample workbook - I cannot troubleshoot a picture, but chances are you are not updating ranges correctly, or the real data is very dufferent.

I hope you don`t fell offended, I tried both suggested formulas.

Nobody is offended.

You haven't updated the ranges to match the real data - of course it won't work!

Provide a more realistic workbook (desensitised).

OK - I'll adapt it for you.

Try this:

In O2 (boerowing one bit from TMS):

=IFNA(DROP(REDUCE(0,TOCOL(B2:B10000,1),LAMBDA(x,y,VSTACK(x,FILTER(K2:N10000,K2:K10000=y,"")&""))),1),"")

In fact, extend the ranges thus:

=IFNA(DROP(REDUCE(0,TOCOL(B2:B15000,1),LAMBDA(x,y,VSTACK(x,FILTER(K2:N15000,K2:K15000=y,"")&""))),1),"")

I have to change your formula to this to get it to work: =IFNA(DROP(REDUCE(0;TOCOL(B2:B10915;1);LAMBDA(x;y;VSTACK(x;FILTER(K2:N10915;K2:K10000=y;"")&"")));1);"")

But that only returns #VALUE!

Why is it I have to change , to ; to get formula to work?

That's why I have provided a workbook - open the workbook and copy the formula from there, please.

Because yours is a European locale.

Regional Settings. Copy the formula from Ali's workbook. Don't reduce the 15000. If anything, make it larger to cope with future expansion.
