Incrementing Indirect Column References Within SUMIF(S)/COUNTIF(S) 13

Most Excel users are aware that, when a formula containing relative column references is copied to further columns, those references are updated accordingly. So, for example, the formula:

=SUMIFS(C:C,$A:$A,"X",$B:$B,"X")

when dragged to the right, will become, successively:

=SUMIFS(D:D,$A:$A,"X",$B:$B,"X")
=SUMIFS(E:E,$A:$A,"X",$B:$B,"X")

etc., etc.

And so we have a relatively (no pun intended) simple means by which we can obtain a conditional sum from successive columns.

But what if the range we wish to increment is being referenced indirectly? For example, what if we are using a version of the above, but in which the sheet being referenced is dynamic, viz:

=SUMIFS(INDIRECT("'"&$A$1&"'!C:C"),INDIRECT("'"&$A$1&"'!A:A"),"X",INDIRECT("'"&$A$1&"'!B:B"),"Y")

where A1 contains the sheet name (e.g. “Sheet1”) which is to be referenced at any given time?

Coercing array returns from CSE-resistant formulas 13

We usually face no problems in cases where we wish to apply a formula to, not just one, but an array of values. And of course we do this by simply committing the formula as an array formula, i.e. with CSE.

However, not all formulas yield so easily, and some stubbornly resist any attempts at coercing an array of returns from them. Here I would like to discuss some techniques which, in addition to array-entry, can help coerce the desired result.

The principal method in such cases is to use a construction involving OFFSET, though a set-up using INDEX is equally viable; indeed, due to its non-volatility, perhaps even preferable. Some cases may require even more coercion than that, and others less. But the one thing they all share in common is that, on its own, array-entry just isn’t enough!
