Hello, I understand that you need to return a list of the headers where a name was found, right?

Yes...

essentially I have some people's names in one column on a worksheet

I want to compare each name against an array of columns on another worksheet and return the headers

Excelchat Expert

The solution to this will depend on how many columns you have for checking because if it's too many, the formula may not fit at all.

User

OK...

User

There are roughly 450 columns

Excelchat Expert
16/08/2018 - 12:50

Oh, if that's the case I don't think it'll fit in a formula.

Excelchat Expert
16/08/2018 - 12:50

Because the way to do this is to have a match per each column and then return the header name if it is a match.

User

yes, that's what I'm looking for

Excelchat Expert

Since it's 450 columns that needs to be checked, I don't think the formula will fit.

User

what's the highest number of columns that it would work for?

User

could split it into "batches" and then concatenate the split results into one final result

Excelchat Expert

You can try that. Here's what I'd suggest. Since we have a very limited amount of time to do this, it would not be possible for me to do it for you, so I'll create a sample formula you can expand yourself, would that be acceptable?

User

That's great

Excelchat Expert

Please create a sample data using the sheet to the right.

User

OK

User

Done

Thank you. Give me a few minutes to figure out the best possible solution for this.

Excelchat Expert

Column B will be your formula just for 3 columns. You can imagine how long this will be for 450 columns.

User
16/08/2018 - 12:59

wow

User
16/08/2018 - 12:59

yeah....

Excelchat Expert

If you have the patience to do it this way, this should be enough but the best approach to this would have to be VBA/Macro.

Excelchat Expert

Unfortunately, we currently do not support VBA Macro solutions.

Excelchat Expert

Here's for the first column:

Excelchat Expert
16/08/2018 - 01:00

=if(isnumber(match(A2,Sheet2!A:A,0)),Sheet2!A$1,"")

Excelchat Expert
16/08/2018 - 01:00

What you need to change is Sheet2!A:A and Sheet2!A$1

Excelchat Expert
16/08/2018 - 01:00

So for the next column it will be:

Excelchat Expert
16/08/2018 - 01:00

if(isnumber(match(A2,Sheet2!B:B,0)),Sheet2!B$1,"")

Excelchat Expert
16/08/2018 - 01:01

Then concatenate them by using the &
