Arrayformula doesn't use relative reference in sheets? - google-sheets

I have columns A:Date, B:amount.
I'd like to use a array formulae to compute the percent rank of the B column in 2 ways, first against the entire data set and second against the data up to that point. I can do this with regular formulae but want to use arrayformula.
=ARRAYFORMULA(if(A4:A <> "",PERCENTRANK(B$4:B,B4:B),))
Works to get percentrank against the entire set of data as expected.
=ARRAYFORMULA(if(A4:A <> "",PERCENTRANK(B4:B,B4:B),))
This is what I tried to use to get the result up to that date, but just gives same result as above.
I'm sure I'm not grasping something about the nature of arrayformula...
Thanks in advance

You could use sumif to get it.
Column C: =filter(B2:B/(sum(B:B)),B2:B<>"")
Column D: =filter(B2:B/(Sumif(A:A,"<="&A2:A,B:B)),B2:B<>"")

Array formula is not working with the combination of Vlookup and Indirect-Match?

I am trying to generate an arrayformula for the whole column but it does not work, when I use the same formula cell by cell, it generates correct value. Here is the formula for F1 cell:
=if(Iferror(vlookup($D1, INDIRECT("$"&"A"&MATCH(E1,$B:$B,0)+1&":$B"),2,false),"")=E1,"",Iferror(vlookup($D1, INDIRECT("$"&"A"&MATCH(E1,$B:$B,0)+1&":$B"),2,false),""))
I am trying to convert it into ArrayFormula like this and put it in F1:
=ARRAYFORMULA(if(Iferror(vlookup($D:$D, INDIRECT("$"&"A"&MATCH($E:$E,$B:$B,0)+1&":$B"),2,false),"")=$E:$E,"",Iferror(vlookup($D:$D, INDIRECT("$"&"A"&MATCH($E:$E,$B:$B,0)+1&":$B"),2,false),"")))
But this does not work and returns empty column, here is the sheet if you want to test it, you can find formula in column F:
https://docs.google.com/spreadsheets/d/13XLZvvdzK_mqr4Ous50cIEfernw2XrPJWvVgt1hFxtk/edit?usp=sharing
Please share your knowledge how to go about it as I am trying to learn formulas starting from basic level? Thank you.
when working with more than one condition, you can usually use FILTER for it. In this case, I used MAP to refer to both columns D and E, and used FILTER to narrow to the matches in A column, and then to those values that were further than the row of the MATCH of E value. Then, with INDEX I chose the first value of that resulting range.
=MAP(D:D,E:E,LAMBDA(d,e,IFERROR(IF(d="","",INDEX(FILTER(B:B,A:A=d,ROW(B:B)>MATCH(e,B:B,0)),1)))))
Unclear of the full scope but from your expected result scenario(in Column F) you seem to be pulling off second match(if any). well in that case try:
=BYROW(D:D,LAMBDA(dx,IF(dx="",,IFNA(FILTER(ARRAY_CONSTRAIN(FILTER(B:B,A:A=dx),2,1),{0;1})))))

Formula works until I make it an arrayformula

I have a formula that works when it is dragged down but it stops working as soon as it's changed to be an array formula - why could this be?
This is the formula that works when dragged down
=IF(AND($W246:W= "Hired",$Y246:Y<>"Y"),"Workforce Needed","Not")
This is an array formula that suddenly doesn't work. (It no longer pulls back "Workforce Needed" when conditions change - despite me running the same test with the original formula and it working then)
=ARRAYFORMULA(
IF(ISBLANK(F91:F),,IF(AND($W91:W= "Hired",$Y91:Y<>"Y"),"Workforce Needed","Not")))
Column W is a data validation drop down (text)
Column Y is an array formula doing a vlookup
Any ideas much appreciated.
The and() function is an aggregating function and will not get row-by-row results in an array formula. To make it work, use Boolean arithmetic, like this:
(W91:W = "Hired") * (Y91:Y <> "Y")
use:
=ARRAYFORMULA(IF(ISBLANK(F91:F),,IF(($W91:W="Hired")*($Y91:Y<>"Y"),
"Workforce Needed","Not")))

How to use vlookup to find the value based on time in another table (google sheet)?

I'm trying to get the values for column C in Table 1 from column H by using vlookup. However, seems like the vlookup doesn't work and return a N/A. I had checked both ISDATE and ISNUMBER for data in column B and column G, they are the same.
One of the possible reason I can think of is because I'm using query function to get the data for column F and column G from Table 1. However, I'm not sure how to solve this so that I can use the vlookup function or any other method so that I can match the value based on the time.
I attached the google sheet link below in case you need it:
https://docs.google.com/spreadsheets/d/17coke3-oyDRLHgz79PDl3KX68kFOEte-aynVe-xEITU/edit?usp=sharing
I've added a new sheet ("Erik Help") with the following formula solution in C2:
=ArrayFormula({"Value";IF(B3:B="",,VLOOKUP(ROUND(B3:B,10),ROUND(G3:H,10),2,FALSE))})
This single formula returns all results for the column.
You were experiencing the effects of floating decimals, meaning numbers generated in different ways are actually different in memory to very fine degrees. I just used ROUND(...,10) on everything to limit that, and it works fine.

Formula that will skip one column when calculating SUM() or similar functions

I'd like to run a =SUM(A1:G1), but always skip one column, regardless if it has value or not.
In this case, it should calculate A1+C1+E1+G1.
Is there another function I could append to SUM() or other similar functions as SUM in order to skip one column?
Thank you!
Using the following method you can calculate any number of alternate columns, without the need of manual +
Suppose your data is in second row onwards, use this formula
=SUMPRODUCT(A2:G2, MOD(COLUMN(A2:G2),2))
Simply a sumproduct of cell values and a array of {1,0,1,0,1...}
Another slight variation
=SUMPRODUCT(A2:G2*ISODD(COLUMN(A2:G2)))
But if the even columns contain letters instead of numbers this will give an error, so you can use instead
=SUMPRODUCT(N(+A1:G1)*ISODD(COLUMN(A1:G1)))
Comparing #AnilGoyal's answer, this works as well
=SUMPRODUCT(A1:G1,--ISODD(COLUMN(A1:G1)))
You can use:
=SUM(INDEX(A1:G1,N(IF(1,{1,3,5,7}))))
Or with Excel O365:
=SUM(INDEX(A1:G1,{1,3,5,7}))
A bit more of a general solution:
=SUMPRODUCT(MOD(COLUMN(A1:G1),2)*A1:G1)
Or with Excel O365:
=SUM(MOD(COLUMN(A1:G1),2)*A1:G1)
Or even:
=SUM(INDEX(1:1,SEQUENCE(4,,1,2)))
Since you included Google-Sheets, I'll throw in an option using QUERY():
=SUM(QUERY(TRANSPOSE(1:1),"Select * skipping 2"))
Maybe a bit more verbose, but very understandable IMO.
Consider something of the format:
=SUM(A1:G1)-INDEX(A1:G1,2)
The 2 in the formula means remove the 2nd item in the part of the row. (so the 999 is dropped)
So the formula =SUM(BZ10:ZZ10)-INDEX(BZ10:ZZ10,2) drops CA10 from the sum, etc.(a similar formula can be constructed for columns)
google sheets:
=INDEX(MMULT(N(A1:H3), 1*ISODD(SEQUENCE(COLUMNS(A:H)))))
=INDEX(IF(ISODD(COLUMN(A:H)), TRANSPOSE(MMULT(TRANSPOSE(
IFERROR(A1:H3*ISODD(COLUMN(A:H)), 0)), 1^ROW(A1:A3))), ))

Index match find closest value with multiple search criteria

I am trying to find a closest absolute value with index match. I looked at several other posts like here but what i am trying to do is a bit different as i want to add multiple search criterias.
As you can see , I am trying to get the absolute closest time for a specific person.
I am using the formula =index(C2:C21,match(F4,B2:B21,-1),match(E4,A2:A21,0)) and I had to copy column B in column C to make my 1st match work. The result is shown in G4. Unfortunately I am struggling to get the correct result.
Effectively I would like use the formula that was posted in the previous post (see link at the top) =INDEX(E2:E21,MATCH(TRUE,INDEX(ABS(D1:D21-I4)=MIN(INDEX(ABS(D2:D21-I4),,)),,),0))
with with a search criteria (the name of the person).
Any help would be much appreciated
Thank you
Thanks #avram
I still end up with some cases where the formula does not work. See below. in G6 and G7 i should get 10:25. (You can ignore column A)
Try this formula in G4,
=index(C$2:C$21, match(min(index(abs(index(C$2:C$21+(B$2:B$21<>E4)*1E+99, , )-F4), , )), if(B$2:B$21=E4, abs(C$2:C$21-F4), 1E+99), 0))
This will work in either google-sheets as a standard (non-array/non-CSE) formula or excel as an array (CSE) formula.
If anyone else wants to tackle this problem with a more elegant formula, you can copy the sample data from this publicly shared google-sheet.
Index match find closest value with multiple search criteria
Perhaps this may exempt a fourth person from retyping the same tired data that the op delivered in image(s).
A very simple approach using a "helper" column with data like:
We want the closest absolute match for larry to 10:15 AM. We enter larry in E1 and 10:15 AM in F1
Then in D2 we enter:
=IF(A2=$E$1,ABS(B2-$F$1),"")
and copy downward. (this is the absolute difference for larry) Finally in E2:
=INDEX(B:B,MATCH(MIN(D:D),D:D,0))
With bigger tables having more columns, it is very easy to add additional criteria if needed.
This answer uses Array Formulas which must be entered using CTRL+SHIFT+ENTER. It's kind of complicated, so I'll do my best to explain and will revise if necessary. Here's a screenshot:
Here is the formula in its raw form; names are entered in column A, Times in Column B.
=INDEX(B1:B7,MATCH(MIN(IF(A1:A7=D2,ABS(E2-B1:B7),"")),IF(A1:A7=D2,ABS(E2-B1:B7),"")))
As you might suspect, it uses INDEX/MATCH to get the job done, but the key is using an IF statement to generate both the search criteria and the array that the MATCH function searches within. Let's break it down.
Sec 1, Match Search Array
IF(A1:A7=D2,ABS(E2-B1:B7),"")
This creates the Search array for the match function. If the name in D2 (our criteria) is equal to the name in the search array, it return the absolute value of the difference between the criteria time and the time in the array we're searching. Otherwise it returns a blank value. Do not use 0 for this as it will skew the match result.
Sec 2, Match Search Criteria
MIN(IF(A1:A7=D2,ABS(E2-B1:B7),""))
This tells us the smallest value in the above array. We use this value as the search criteria in the MATCH function.
Sec 3, putting 1 & 2 Together
MATCH(MIN(IF(A1:A7=D2,ABS(E2-B1:B7),"")),IF(A1:A7=D2,ABS(E2-B1:B7),"")) This searches for the smallest abs difference defined in Section 2 within the array created in Section 1 and returns the row number.
Sec 4, Indexing the times
=INDEX(B1:B7,MATCH(MIN(IF(A1:A7=D2,ABS(E2-B1:B7),"")),IF(A1:A7=D2,ABS(E2-B1:B7),"")))
This returns the time value from column B in whatever row is identified by the Match function above.
Hopefully this all makes sense. Remember to enter it as an array formula.
