Google Spreadsheet: ArrayFormula and Filter - google-sheets

I realize that there are multiple questions with this title, but I don't understand the answers to them, or it is not directly related to my issue.
I'm trying to avoid manually "dragging" a formula to duplicate it for each row.
Formula looks like this
=IF(ISBLANK(A6),
"",
COUNT(FILTER(Data!C$2:C,
Data!A$2:A = A6,
Data!B$2:B >= B$2,
Data!B$2:B <= B$3,
Data!C$2:C >= E$3,
Data!C$2:C <= E$2)))
I'm not sure all the anchors are needed when using ARRAYFORMULA.
The A column is the one I want to "interate", the rest of the ranges should evaluate to whatever they're evaluating to now.
I have tried this:
=ARRAYFORMULA(IF(ISBLANK(A6:A),
"",
COUNT(FILTER(Data!C$2:C,
Data!A$2:A = A6:A,
Data!B$2:B >= B$2,
Data!B$2:B <= B$3,
Data!C$2:C >= E$3,
Data!C$2:C <= E$2))))
In which the A6:A seems to evaluate correctly to each cell in the A column. However, the ranges from the Data sheet also seem to evaluate to a single value and not the ranges.
Am I missing something or do I not understand how ARRAYFORMULA works?

filter is an arrayformula by itself → it can't be used in another arrayFormula because Sheets cannot handle array of arrays.
Workaround
You are looking for countifs arrayFormula, which is solved with mmult:
=arrayformula(TRANSPOSE(MMULT(TRANSPOSE((Data!B$2:B>=B2)*(Data!B$2:B<=B3)*(Data!C$2:C<=E2)*(Data!C$2:C>=E3)),--(Data!A$2:A=TRANSPOSE(A6:A10)))))
Explanation
=arrayformula(TRANSPOSE(MMULT(...,...)
^^^^^ mmult will count for 1's and 0's in intersection
of conditions
...TRANSPOSE((Data!B$2:B>=B2)*(Data!B$2:B<=B3)*(Data!C$2:C<=E2)*(Data!C$2:C>=E3))...
^^^^ any number of 'plain' conditions goes here
...--(Data!A$2:A=TRANSPOSE(A6:A10)...
^^^^ all 'filter' conditions go here, you have only 1 of those

Array formula for a rolling AVERAGEIF formula?

I have a working formula that I need to drag to autofill down a column and want to make it into an array formula:
=AVERAGEIF(INDIRECT("A2:A"&ROW()), ">=0",INDIRECT("A2:A"&ROW()))
So if you put this formula in column B it will take the values in column A and continually average them going down, skipping any values that are less than 0. Here is an example screenshot: https://i.imgur.com/nRq8hAH.png
How can I make an array formula for this?
This formula comes close but I couldn't figure out how to add the ">=0" conditional:
=ArrayFormula(IF(LEN(A2:A),SUMIF(ROW(A2:A),"<="&ROW(A2:A),A2:A)/COUNTIF(ROW(A2:A),"<="&ROW(A2:A)),))
Lambda Update
There is no longer any need to use ArrayFormula for this.
=MAP(SEQUENCE(COUNTA(A2:A)),
LAMBDA(rowOff,
AVERAGEIF(OFFSET(A2,0,0,rowOff),">=0"))
)
How?
For each element rowOff in 1..# items in column:
Use AverageIf to get the average of everything starting at the top taking rowOff rows, excluding everything >=0
Old solution
Here's a single formula that can go into B2 (no need to drag), but it's fairly complicated:
=ArrayFormula(IFERROR(IF(LEN(A2:A),MMULT(TRANSPOSE((SEQUENCE(COUNTA(A2:A),1,2)<=TRANSPOSE(SEQUENCE(COUNTA(A2:A),1,2)))*FILTER(A2:A,LEN(A2:A))),--(FILTER(A2:A,LEN(A2:A))>0))/COUNTIFS(SEQUENCE(COUNTA(A2:A)),"<="&SEQUENCE(COUNTA(A2:A)),FILTER(A2:A,LEN(A2:A)),">=0"),"")))
Readable:
=ArrayFormula(IFERROR(
IF(
LEN(A2:A),
MMULT(
TRANSPOSE(
(SEQUENCE(COUNTA(A2:A),1,2)<=
TRANSPOSE(SEQUENCE(COUNTA(A2:A),1,2))
)*FILTER(A2:A,LEN(A2:A))
),
--(FILTER(A2:A,LEN(A2:A))>0)
)/
COUNTIFS(
SEQUENCE(COUNTA(A2:A)),
"<="&SEQUENCE(COUNTA(A2:A)),
FILTER(A2:A,LEN(A2:A)),
">=0"
),
""
)
))
How?
We can achieve a running sum using MMULT on a Lower Triangular Matrix of size COUNTA(A2:A) of all 1's and all non blanks of A2:A, which we filter out if the number is negative. In this case, it produces {2;2;6;6;6;6}.
The COUNTIFS() produces an array of the number of elements we want to divide by. Here, it's {1;1;2;2;3;4}
Then ignore any blanks at the with IF.
Blank out any errors with IFERROR. (#DIV/0! errors can happen if the leading numbers are negative.)
Perhaps, this formula can help:
=ARRAYFORMULA(AVERAGE(IF($A$2:A2>=0,$A$2:A2,"")))

ArrayFormula with GoogleFinance dynamic date

First of all, i'm not a powerful sheets user :)
I'm trying to use GOOGLEFINANCE to calculate amounts in multiple currencies.
I use this formula:
=IF($A2;
IF(
$C2:C;
$C2:C;
IF(
$D2:D;
$D2:D*INDEX(GoogleFinance("CURRENCY:USDUAH";"close";$A2);2;2);
$E2:E*INDEX(GoogleFinance("CURRENCY:EURUAH";"close";$A2);2;2)
));
0)
A-column contains dates,
C,D,E - amounts in 3 different currencies.
IFs are just to prioritize columns :)
The formula works well but i need to "extend" it each time i add row - to increment
$A2 -> $A3 to get rate for specified date.
I try to use ArrayFormula but it turns out it keeps reference to $A2 so i get same rate irrelevant from date specified in A-cells.
I have created sample sheet to illustrate:
https://docs.google.com/spreadsheets/d/1K2TbGIWl7JacYKiWgwwmJfelxJ-7fa9F9obp5XswW18/edit?usp=sharing
I have allowed editing by anyone, so if you decide to edit - please don't remove anything :) also you can drop your username in sticky row(above your proposed solution)
Is there a way to apply ArrayFormula to this to make it work?
Maybe you can provide more readable solution to nested IFs.
try:
=ARRAYFORMULA(IF(A2:A<>"";
IF(C2:C<>""; C2:C;
IF(D2:D<>""; VLOOKUP(TO_TEXT(A2:A);
TO_TEXT(QUERY(GOOGLEFINANCE("CURRENCY:USDUAH";
"close"; MIN(A:A); MAX(A:A)+1);
"offset 1 format Col1'dd.mm.yy'"; 0)); 2; 0)*1;
VLOOKUP(TO_TEXT(A2:A);
TO_TEXT(QUERY(GOOGLEFINANCE("CURRENCY:EURUAH";
"close"; MIN(A:A); MAX(A:A)+1);
"offset 1 format Col1'dd.mm.yy'"; 0)); 2; 0)*1)); ))
There is a new simpler and more flexible method now since the introduction of LAMBDA and its helper functions in Google Sheets in August 2022.
Assuming dates in A2:A, and amounts in UAH, USD, EUR in C2:C, D2:D, E2:E respectively, then the following formula will work, e.g. in cell F2:
=MAP(A2:A;C2:C;D2:D;E2:E;
LAMBDA(date;uah;usd;eur;
IFS(
uah;uah;
usd;usd*INDEX(GOOGLEFINANCE("currency:usduah";"price";date);2;2);
eur;eur*INDEX(GOOGLEFINANCE("currency:euruah";"price";date);2;2);
ISBLANK(date);)))
The trick here is that MAP(LAMBDA) calculates the specified formula for each row of the input array separately (effect similar to manually expanding the formula over the whole range), whereas ARRAYFORMULA passes the whole array as an argument to the formula (GOOGLEFINANCE is special and doesn't work intuitively with such input).
This general method with MAP(LAMBDA) can now be used to pass any arguments to GOOGLEFINANCE in a way one would otherwise expect to do with ARRAYFORMULA.
Try This One:
=arrayformula(
IF(query(arrayformula(if(A2:A="",False,True)),
"Select * where Col1=True"),
IF( $C2:C,
$C2:C,
IF( $D2:D,
$D2:D*INDEX(GoogleFinance("CURRENCY:USDUAH","close",$A2),2,2),
$E2:E*INDEX(GoogleFinance("CURRENCY:EURUAH","close",$A2),2,2))),0))

Is there a function that can create an expanding array formula that conditionally sums a column based on multiple criteria?

To start, this is my first time posting and so please let me know if I can fix my post in any way to make it easier to answer.
I am trying to create an auto-expanding array formula
I have a sheet with my investment asset mix that including amounts of shares owned of each particular stock, and a sheet that tracks when I receive dividends. My goal is to write an automatically expanding array formula that will sum up the amount of shares that own of a stock on the date a dividend is received and return that value. I have written three different formulas that all accomplish this but none of them will auto-expand as an array.
I'm sure there are a lot of solutions I've overlooked. To boil it down, I need an expanding array formula that will sum the "Shares" column of my asset mix sheet ('Asset Mix'!D2:D, or 'AssetMixShares') conditionally. The name of the stock entered in 'Dividends'!C2:C needs to match the name of the stock in 'Asset Mix'!A2:A (or the named range 'AssetMixStocks'). It then needs to check the dates in 'Asset Mix'!C2:C (or 'AssetMixDates') against the dates in 'Dividends'!A2:A and sum all share amounts where the purchase date is less than (earlier than) the Ex-Dividend Date.
I could probably write some sort of vlookup array on the "Running Total" column -- 'Asset Mix'!E:E -- that would solve the issue, but I'm hoping to eliminate that column. I feel very strongly that what I'm trying to do should be possible without the help of a running total column -- I just don't have the knowledge.
I have tried countless functions and formulas, but the four that I currently have in my example worksheet are SUM, SUMPRODUCT, DSUM, and QUERY.
Attempt 1
SUM and IF
=ArrayFormula(SUM(IF('Asset Mix'!A:A=C2,IF('Asset Mix'!C:C<A2,'Asset Mix'!D:D))))
Attempt 2
SUMPRODUCT
=({arrayformula(SUMPRODUCT(--((AssetMixStock=(indirect("C"&ROW())))*(AssetMixDate<(indirect("A"&ROW())))),AssetMixShares))})
Attempt 3
DSUM
=DSUM('Asset Mix'!A:E,"Shares",{"Date","Stock";"<"&A2,C2})
Attempt 4
QUERY
=arrayformula(query(AssetMix,"Select sum(D) where A = '"&C2:C&"' and C < date'"&(text(year(A2:A),"0000") & "-" & text(month(A2:A),"00") & "-" & text(day(A2:A),"00"))&"' label sum(D) ''",0))
These will all work, as long as I manually drag the formula down, but I want to write some sort of formula that will auto-expand to the bottom of the Dividends sheet.
I have tried to create a Dummy sheet that has both of the relevant sheets. Please let me know if you can access it -- the link is below.

Thanks so much for getting this far and any help you can provide!
We can focus in the first formula to understand a way to make it "self-expandable". As we see it contains references to the cells A2 and C2 in "Dividends" sheet:
=ArrayFormula(SUM(IF('Asset Mix'!A:A=C2,IF('Asset Mix'!C:C<A2,'Asset Mix'!D:D))))
Every time some data appears in these columns (A and C), the formula should work. We can control the presence of the formula by onEdit trigger, if editing is manual. Consider the code:
function onEdit(e) {
var sheet = SpreadsheetApp.getActive().getActiveSheet();
if (sheet.getName() == 'Dividends') {
var row = e.range.getRow();
for (var offset = 0; offset < e.range.getHeight(); offset++) {
sheet.getRange(3, 10).copyTo(sheet.getRange(row + offset, 10));
}
}
}
It checks any modification on the sheet "Dividends" and copies required formula to the modified row(s). This way the formula is expanded for other rows in use.
Well, it's solved! I'll leave this up in case anyone else has the same question.
A kind soul explained the magic of MMULT() to me, and wrote this solution.
=ARRAYFORMULA(MMULT((C2:C=TRANSPOSE('Asset Mix'!A2:A))*(A2:A>TRANSPOSE('Asset Mix'!C2:C)),N('Asset Mix'!D2:D))

Google Spreadsheet Function That Sums Numbers In A Column When the Row Contains An EXACT Text

I've been at this problem for a while now. I am trying to sum numbers under a specific column when the rows equal a certain text and then display that sum on a different sheet. So far I came up with this formula: =IF(EXACT(A2,Table!A2:A)=TRUE,SUM(Table!C2:C)); however the only problem is that is sums everything in column C (which makes sense).
I wish there was a way to do something like the following: SUM(Table!C2:C where EXACT(A2,TABLE!A2:A)=TRUE). I've also tried the SUMIF(), DSUM(), and QUERY() functions to no avail. I must be getting logically tripped up somewhere.
Figured it out: =SUM(FILTER(Table!E4:E, EXACT(Table!A4:A,A4)=TRUE)).
=sum ( FILTER (b1:b10, a1:a10 = "Text" ) )
// the above formula will help you to take the sum of the values in column B when another column A contain a specific text.
The formula is applicable only in Google Spreadsheets

pulling row number into query google spreadsheet

I have a data set that looks like this: starting on A1 with "1"
1 a
2 b
3 c
4 d
Column A is an arrayformula =arrayformula(row(b1:b))
Column B is manual input
i want to query the database and finding the row of the item by match column B so i have code as such
=query("A1:B","select A where B like '%c%')
this should give me "3"
My question:
is there a way to pull the 1-4 numbers into the query line? with something like array formula row(b1:b). I don't want to waste an extra column on column A
so basically I want just the manual input and when i query it gives me the row number.
No script code please.
I've tried a few things and it didn't work.
Looking for a solutions that starts with
=query()
You can also use a formula to pull in more than one row in the dataset which matches the condition, if this is important to you:
=arrayformula(filter(row(B:B); B:B="c"))
And you can have wildcard type operators, under certain circumstances (you are going to match text or items that can look like text (so numbers can be treated as text - but boolean will need more steps); that the dataset is not huge), using regular expressions. e.g.
=arrayformula(filter(row(B:B); regexmatch(B:B, "(c|d)")))
You could also use standard spreadsheet wildcard operators, e.g.
=arrayformula(filter(row(B:B); countif(B:B, "*c*")))
Explanation: In this case, the filter will be true when countif is greater than zero, i.e. when it sees something with a letter c in it, since spreadsheets see a value greater than zero as a boolean true and so, for that row where there is a countif match, there will be a a filter match, and so it will display that row (indeed, it is a similar situation with the regexmatch creating a true when there is a match of either c or d, in the case above).
Personally, I wanted to learn regex a bit, so I would go towards the regexmatch option. But that is your choice.
You can also, of course, create the match outside of the cell. This makes it easy to create a list of matches that you want to satisfy elsewhere on the sheet. So you could have a column of words or parts of words, from Z2 downwards, and then join them together in cell Z1 for example like this
="("&join("|",filter(Z2:Z50,len(Z2:Z50)))&")"
Then your filter function would look like this:
=arrayformula(filter(row(B:B), regexmatch(B:B, Z1)))
If you want to use like operator in the query function, you can try something like this:
=arrayformula(query(if({1,0}, B:B,row(B:B)),"select Col2 where Col1 like '%c%' "))
You can also use the regular expressions in the query function, for example:
=arrayformula(query(if({1,0}, B:B,row(B:B)),"select Col2 where Col1 matches '(.*c.*|.*d.*)' "))
I'm not entirely clear on the question, but as I understand it, you want to be able to enter a formula, and have it return the row number of the matched item in a range? I'm not sure where array formulas come in.
If I've understood your question correctly, this should do the trick:
=MATCH("C",B1:B,0)
In your example, this returns 3.
Please forgive me if I've misunderstood your question.
Note: If there are multiple matches, this will return the row number for the first instance of your search.
=QUERY({A1:A,ARRAYFORMULA(ROW(A1:A))},"SELECT Col2 WHERE Col1 LIKE '%c%'")
