If I use =Small({VALUE(DV147),VALUE(DZ147),VALUE(ED147),VALUE(EH147)},2) it does not work. But, if I use SUM and the Value(-----) amounts, it works. What am I doing wrong?
Note: The numbers are stored as text in those cells for other reasons.
A couple of ways:
=SMALL(VALUE(T(INDIRECT({"DV147","DZ147","ED147","EH147"}))),2)
or:
=SMALL(VALUE(T(OFFSET(DV147,,{0,4,8,12}))),2)
To answer your specific question:
What am I doing wrong?
The elements of an array constant need to be constants. Formulas/Functions cannot be components of an array constant. Although you can certainly use formulas to create an array, as shown by XOR LX in his answer.

I just want to get the sum of all the values on the left side and not include the date.
Try SUMPRODUCT(). Assuming, you have space after value.
=SUMPRODUCT(--LEFT(A1:A4,SEARCH(" ",A1:A4)))
What about:
=SUM(--TEXTSPLIT(A1:A4," "))
Hey, Try this, even the data is inconsistent with more spaces, this will work.
=SUMPRODUCT(LEFT(A2:A6,SEARCH("-",SUBSTITUTE(A2:A6," ",""))-1)+0)
A slight variation to the previous proposals for two reasons:
Don’t need to invoke SUMPRODUCT(). If - - has been used to force enumeration, then SUM() is sufficient.
While TEXTSPLIT() works, you’ll run into problems if your column length is one. TEXTSPLIT will create a horizontal array with multiple values if applied to a range with only one row, producing ambiguity and a potential error.
Thus:
=SUM(--TEXTBEFORE(A2:A6," "))
is more versatile.
Textsplit, Textbefore functions are available on office365. If the user is not using office365, sumproduct would be the preferrable choice.
Alright this should be a simple one.
I apologize in case it has been already solved, but I can only find posts related to solving this issue with programming languages and not specifically to EXCEL.
Furthermore, I could find posts that address a sub-problem of my question (e.g. regarding limitation of certain EXCEL functions) and should solve/invalidate my request but maybe, just maybe, there is a workaround.
Problem statement:
I want to calculate the minimum value for each column in an EXCEL matrix. Simply enough, I want to input a 2D array (mxn matrix) in a function and output an array with dimension 1xm where each item is the minimum value MIN(nj) of each nj column.
However, I want to solve this with specific constraints:
Avoid using VBA and other non-function scripting: that I could devise myself;
All in one function: what I want to achieve here is to have one and one function only, not split the problem into multiple passages (such as for example copypasting a MIN() function below each column, that wouldn't do it);
The result should be a transposable array (which is already ok, I assume);
Where I am stranded with my solution so far:
The main issue here is that any function I am trying to use takes the entire matrix as a single array input and would calculate the MIN() of the entire matrix, not each column. My current (not working) function for an exemplary 4x4 matrix in range A1:D4 would be as below (the part in bold is where it is clearly not working):
=MIN(INDEX(A1:D4,SEQUENCE(4,4,1,1)))
which ofc does not work, because INDEX() does probably not "understand" SEQUENCE() as an array of items to take into account. Another, not working, way of solving this is to input a series of ranges (A1:A4;B1:B4;C1:C4;D1:D4) so that INDEX() "understands" the ranges as single columns, but ofc does not know and I do not know sincerely how to formulate that. I could use INDIRECT() in some way to reference the array of ranges, but do not know how and could find a way by searching online.
Fundamental question is: can a function, which works with single arrays, also work with multiple arrays? Basically, I do not know how to communicate an EXCEL array formula, that each batch of data I am inputting is a single array and must be evaluated separately (this is very easily solved with for() cycles, I know).
Many thanks for any suggestion and any workaround, any function and solution works as longs as it fits in the constrains defined above (maybe a LAMBA() function? don't know).
This is ofc a simplification of a way more complex problem (I am trying to calculate the annual mean temperature evolution for a specific location by finding the value - for each year from 1950 to 2021 - that is associated to the lat/lon coordinates that are the nearest to the one of the location inputted, given a netCDF-imported grid of time-arrayed data; the MIN() function is used to selected the nearest location, which is then used, via INDEX() to find temp data). I need to do this in one hit (meaning just pasting the function, which evaluates a matrix of data that is referenced by a fixed range), so that I can just use it modularly for other data sets. I already have a working solution, which is "elegant"* enough, but not "elegant"* as the one I could develop solving this issue.
*where "elegant"= it saves me one click every time for 1000+ datasets when applying the function.
If I understand your problem correct then this should solve it:
=BYCOL(A1:D4,LAMBDA(d,MIN(d)))
Ever since I learnt that Excel is now Turing-complete, I understood that I can now "program" Excel using exclusively formulas, therefore excluding any use of VBA whatsoever.
I do not know if my conclusion is right or wrong. In reality, I do not mind.
However, to my satisfaction, I have been able to "program" the two most basic structures of program flow inside formulas: 1- branching the control flow (using an IF function has no secrets in excel) and 2- loops (FOR, WHILE, UNTIL loops).
Let me explain a little more in detail my findings. (Remark: because I am using a Spanish version of Excel 365, the field separator in formulas is the semicolon (";") instead of the comma (",").
A- Acumulator in a FOR loop
B- Factorial (using product)
C- WHILE loop
D-UNTIL loop
E- The notion of INTERNAL/EXTERNAL SCOPE
And now, the time of my question has arrived:
I want to use a formula that is really an array of formulas
I want to use an accumulator for the first number in the "tuple" whereas I want a factorial for the second number in the tuple. And all this using a single excel formula. I think I am not very far away from succeeding.
The REDUCE function accepts a LET function that contains 2 LAMBDAS instead of a single LAMBDA function. Until here, everything is perfect. However, the LET function seems to return only a "single" function instead of a tuple of functions
I can return (in the picture) function "x" or function "y" but not the tuple (x,y).
I have tried to use HSTACK(x,y), but it does not seem to work.
I am aware that this is a complex question, but I've done my best to make myself understood.
Can anybody give me any clues as to how I could solve my problem?
Very nice question.
I noticed that in your attempts you have given REDUCE() a single constant value in the 1st parameter. Funny enough, the documentation nowhere states you can't give values in array-format. Hence you could use the 1st parameter to give all the constants in (your case; horizontal) array-format, and while you loop through the array of the 2nd parameter you can apply the different types of logic using CHOOSE():
=REDUCE({0,1},SEQUENCE(5),LAMBDA(a,b,CHOOSE({1,2},a+b,a*b)))
This way you have a single REDUCE() function which internal processes will update the given constants from the 1st parameter in array-form. You can now start stacking multiple functions horizontally and input an array of constants, for example:
=REDUCE({0,1,100},SEQUENCE(5),LAMBDA(a,b,CHOOSE({1,2,3},a+b,a*b,a/b)))
I suppose you'd have to use {0\1} and {1\2} like I'd have to in my Dutch version of Excel.
Given your accumulator:
Formula in A1:
=REDUCE(F1:G1,SEQUENCE(F3),LAMBDA(a,b,CHOOSE({1,2},a+b,a*b)))
So I quite often find myself doing tasks on Excel which involve evaluating a text string as an array. Generally speaking I just use this:
Function EVAL(Ref As String)
EVAL = Evaluate(Ref)
End Function
So the formula will be, for example:
=EVAL("{"&CHAR(34)&SUBSTITUTE(TEXTJOIN(";",TRUE,MID(Index[Industries],2,LEN(Index[Industries])-2)),";",CHAR(34)&";"&CHAR(34))&CHAR(34)&"}")
The cells in this example will have contents like:
;Automotive;Rail;Energy;
;Automotive;Rail;
;Energy;
;Automotive;Aerospace;
(As it happens this is the precise problem I'm stuck on right now, though it has come up in different ways in the past.)
This has worked for me in the past, but I've been running into difficulties lately.
I have come to the conclusion it isn't working because application.evaluate, it turns out, has a character limit of 255. I've seen examples of VBA tricks to bypass this for text strings that are formulas rather than arrays, but copy-pasting those they don't seem to work for when I'm using it to interpret a text string as an array rather than as a formula.
Is there some trick to get this to work? (Or, indeed, is there some alternative method to achieve this altogether?)
Right, as per my comments, if you are using ms365, you could avoid your workbook to be xlsm just because you need to split values into an array. Make use of what is available with native functions, for example:
Formula in C2:
=TEXTSPLIT(CONCAT(A1:A4),,";",1)
Formula in D2:
=FILTERXML("<t><s>"&SUBSTITUTE(CONCAT(A1:A4),";","</s><s>")&"</s></t>","//s[node()]")
Note 1: As per time of writing you'd need to enable the BETA-channel to gain access to TEXTSPLIT(), and if I recall correctly your version (2203) is allowed to start using this function. Just google how to get access and update your Excel.
Both options can obviously be nested inside the UNIQUE() function.
Note 2: If at any point CONCAT()'s limits are reached (32767 characters, thanks #ScottCraner), maybe you can avoid using that with help of the lambda's helper function REDUCE():
=TEXTSPLIT(REDUCE("",A1:A4,LAMBDA(a,b,a&b)),,";",1)
Note 3: In case you can't update your Excel just yet, and you wonder how to use FILTERXML(), don't mind me refering you to another post I wrote a while back here.
I'm trying to create a pricing matrix for products but using Index/Match or SumProduct formulas are proving to be a nightmare for me, I'm wondering if VBA would be easier?
Essentially if a product width or height is in between two figures, I need the price quoted to take on the next pricing bracket. (NB: Rounding up or using Ceiling functions within the formula doesn't work for me either)
Examples of the code I've tried using are:
=SUMPRODUCT(--(HeightRange=CEILING(Height,1000))*--(WidthRange=CEILING(Width,10))*PriceRange)
=INDEX(PriceRange,MATCH(MIN(ABS(HeightRange-Height)),ABS(HeightRange-Height),-1),MATCH(MIN(ABS(WidthRange-Width)),ABS(WidthRange-Width),-1))
Example Table:
Use:
=INDEX(B:J,MATCH(N3,A:A),MATCH(M3,B$3:J$3))
You could make use of =AGGREGATE() like so:
=INDEX(A:E,AGGREGATE(15,3,(($A$4:$A$11>=N3)/($A$4:$A$11>=N3))*ROW($A$4:$A$11),1),AGGREGATE(15,3,(($B$3:$J$3>=M3)/($B$3:$J$3>=M3))*COLUMN($B$3:$J$3),1))
You can use directly formulas just like both guys said above...
Mine here:
=INDEX($A:$J,MATCH($N3,$A:$A,0),MATCH($M3,B$3:J$3,0))
