SUMIF Formula that stops at a certain point and does not include the stop point

Hi, welcome to the forum

You would use SUMIF() for this, not index/match

If you still have a problem, upload a small (clean) sample workbook (not a pic) of what you are working with, and what your expected outcome would look like.

Assuming cell $A$1 has the Dec-14 date:

Make sure to Ctrl+Shift+Enter to add the { } brackets to the above array formula.
(ETA: Wait, it seems the above does not need the brackets..)

Monimonika, you would only include {} (using CSE) if you are working with an ARRY formula - that is not an array formula

And, if that formula actually works for the OP, then perhaps a sumifS() would be more efficient...
=SUMIFS($E$3:$E$17,$C$3:$C$17,"Invoice",$D$3:$D$17"<"&$A$1)

"<>X" = not equal to X
"<>X" = is not X

How was a cell reference supposed to be entered?

If you're testing for something like range = X then just use the cell reference of X:

A1 = X

SUMIFS(C1:C10,D1:D10,A1,...)

If you're testing for something like range > 0 then use this...

A1 = 0

SUMIFS(C1:C10,D1:D10,">"&A1,...)

Probably the best way to learn how a function works and what the required syntax is, is to use the Fx icon to the left of the formula bar. Start by typing in the function eg =sumifs( then click the Fx icon - a window will open that will show you exactly what excel expects for/each argument

Edited: didn't reaad the replies properly before posting.

Thanks all. SUMIF with the date criteria worked perfectly.

Based on your last post it seems that you are satisfied with the solution(s) you've received but you haven't marked your thread as SOLVED. If your problem has not been solved you can use Thread Tools (located above your first post) and choose "Mark this thread as unsolved".
Thanks.
