Sum returned values from arrayformula()? - google-sheets

I have a long list of values in a row that I need to perform several functions/vlookups on, multiply them all together and then sum all the final values. There are over 50 different values in a row so I'm trying to come up with a way to do this without manually typing out vlookups for each column.
Here is the formula I put together, however it seems to not be returning the correct value:
=sum(arrayformula(vlookup(offset($A$1,0,{9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54}),Input!$E:$F,2,FALSE)
*offset(indirect("$A"&ROW()),0,{9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54})))
+F6+BD6
It's as if it's doing what I want for some of the values, but not summing them all. Debugging this is an absolute pain, so I'm wondering if I'm even going about this in the right way.
Is there a better way to go about this? I'm wondering if the problem is that I've got two sets of arrays embedded in this function.

Converting a multi column range into one column

I have an instance where I would love to be able to get a column of all the unique names in a range. The problem I am having is that the range is multicolumn.
Let's assume my data is in A1:B3
This works fine if I do:
=unique({A1:A3;B1:B3;C1:C3})
But if that range is named and I do
=unique(NamedRange) or =unique(A1:C3)
Then it will spill over the column. Worse if I want to filter or sort the results in the same formula and then run into errors because the formulas want single column/row or the rows/columns don't match anymore.
I don't deal with named ranges a lot, but I did just make a formula today that had 10 columns in it that I stuck into a range like that so that I could do a complex (for me) filter that gave me the difference of two different ranges, similar to: =FILTER({B4:B93;C4:C93;D4:D93;E4:E93;F4:F93}, NOT(COUNTIF(H5:H, {B4:B93;C4:C93;D4:D93;E4:E93;F4:F93}))). I would REALLY love if I could clean that up and make that messy set B4:F instead.
Is there any formula level function that could stick these all in one column?
Usually I am looking to do other things with it like sort and filter and the multiple columns get even messier.
Thanks for your time. I DID try searching for this, but I could not seem to find the answer.
Use FLATTEN:
=UNIQUE(FLATTEN(A1:C3))
or
=UNIQUE(FLATTEN(NamedRange))

Is there a way to specify an input is a single cell in Google Sheets?

I want to iterate over an array of cells, in this case B5:B32, and keep the values that are equal to some reference text in a new array.
However, SPLIT nowadays accepts arrays as inputs. That means that if I use the array notation of "B5:B32" within ARRAYFORMULA or FILTER, it treats it as a range, rather than the array over which we iterate one cell at a time.
Is there a way to ensure that a particular range is the range over which we iterate, rather than the range given at once as an input?
What I considered was using alternative formulations of a cell, using INDEX(ROW(B5), COLUMN(B5)) but ROW and COLUMN also accept array values, so I'm out of ideas on how to proceed.
Example code:
ARRAYFORMULA(
INDEX(
SPLIT(B5:B32, " ", 1), 1
) = "Some text here"
)
Example sheet:
https://docs.google.com/spreadsheets/d/1H8vQqD5DFxIS-d_nBxpuwoRH34WfKIYGP9xKKLvCFkA/edit?usp=sharing
Note: In the example sheet, I can get to my desired answer if I create separate columns containing the results of the SPLIT formula. This way, I first do the desired SPLITS, and then take the values I need from that output by specifying the correct range.
Is there a way to do this without first creating an output and then taking a cell range as an input to FILTER or other similar functions?
For example in cell C35 I've already gotten the desired SPLIT and FILTER done in one go, but I'd still need to find a way to sum up the values of the first character of the second column. Doing this requires that I take the LEFT value of the second column, but for that I need to output the results and continue in a new cell. Is there a way to avoid this?
Ralph, I'm not sure if your sample sheet really reflects what you are trying to end up with, since, for example, I assume you are likely to want the total of the hours per area.
In any case, this formula extracts all of the areas, and the hours worked, and is then easy to do further calculations with.
=ArrayFormula({REGEXEXTRACT({C5:C9;D5:D9;E5:E9;F5:F9;G5:G9;H5:H9},"(.*) \d"),
VALUE(REGEXEXTRACT({C5:C9;D5:D9;E5:E9;F5:F9;G5:G9;H5:H9}," (\d+)hrs"))})
Try that in cell E13, to see the output.
The first REGEXEXTRACT pulls out all the text in front of the first space and number, and the second pulls out all the digits in a string of " #hr" in each cell. These criteria could be modified, if necessary, depending on your actual requirements. Note that it requires the use of VALUE, to convert the hours from text to numeric values, since REGEXEXTRACT produces text (string) results.
It involved concatenating your multiple data columns into one long column of data, to make it simpler to process all the cells in the same way.
This next formula will give you a sum, for whatever matching room/task you type into B6, as an example.
=ArrayFormula(QUERY({REGEXEXTRACT({C5:C9;D5:D9;E5:E9;F5:F9;G5:G9;H5:H9},"(.*) \d"),
VALUE(REGEXEXTRACT({C5:C9;D5:D9;E5:E9;F5:F9;G5:G9;H5:H9}," (\d+)hrs"))},
"select Col1, sum(Col2) where Col1='"&B6&"' group by Col1 label sum(Col2) '' ",0))
I will also answer my own question given what I know from kirkg13's answer and other sources.
Short answer: no, there isn't. If you want to do really convoluted computations with particular cell values, there are a few options and tips:
Script your own functions. You can expand INDEX to accept array inputs and thereby you can select any set of values from an array without outputting it first. Example that doesn't use REGEXMATCH and QUERY to get the SUM of hours in the question's example data set: https://docs.google.com/spreadsheets/d/1NljC-pK_Y4iYwNCWgum8B4NJioyNJKYZ86BsUX6R27Y/edit?usp=sharing.
Use QUERY. This makes your formula more convoluted quite quickly, but is still a readable and universally applicable method of selecting data, for example particular columns. In the question's initial example, QUERY can retrieve only the second column just like an adapted INDEX function would.
Format your input data more effectively. The more easily you can get numbers from your input, the less you have to obfuscate your code with REGEXMATCHES and QUERY's to do computations. Doing a SUM over a RANGE is a lot more compact of a formula than doing a VALUE of a LEFT of a QUERY of an ARRAYFORMULA of a SPLIT of a FILTER. Of course, this will depend on where you get your inputs from and if you have any say in this.
Also, depending on how many queries you will run on a given data set, it may actually be desirable to split up the formula into separate parts and output partial results to keep the code from becoming an amalgamation of 12 different queries and formulas. If the results don't need to be viewed by people, you can always choose to hide specific columns and rows.

In Google Sheets, why does rank() treat two identical values differently?

I have a sheet with four values that I believe are all equal (i.e. =A1=B1 returns TRUE for each pair). However, when I use rank() on a list with those values, they receive different ranks.
To my knowledge, I'm not doing anything strange, such as a workaround to avoid duplicates. (In this scenario, I want duplicate ranks.) The values I'm trying to rank() were the result of a trunc(sum(...),1), so there aren't any hidden decimals places that I'm not noticing.
I'm just using rank(A1,A1:B1) and arrayformula(rank(A1:B1,A1:B1). These two formulas return different results, even.
Why is rank() treating these numbers as different? Is there some kind of flag or extra property on the cells that's not normally visible that is making them different?
This situation is a little hard to explain without seeing the data, so I've recreated the situation in this sheet:
https://docs.google.com/spreadsheets/d/1cL_15WnKgrxhJfT5lYYIg4sRAzaAzbpP7nH9hju1Rv4/edit?usp=sharing
It has to do with the Floating Point Error than with RANK.
In any case and since you are trying to see if " ...there aren't any hidden decimals places that's I'm not noticing" you could follow a different approach.
Using the ROUND function, round the values of your trunc(sum(...),1) results to however many decimal places you may need. OR
From the top menu choose Format> Number> More formats> Custom number formats and create your own
Following that, you will be able to visually spot the differences.
Additionally you can use the RANK function

How to Find out if a column contains any duplicates

I have a column of numbers. I want to know if there are any duplicates. I don't need to know how many or what their value is. I just want to know if there are any.
The best way I could figure out was to have another column of equal height to the column of numbers, with the formula:
=countif(A:A,A1)>1
So this will put a TRUE next to every number that has one or more duplicates in the list.
From here I need to see if this second column contains a TRUE.
So I have a final cell with this formula in it:
=lookup(true, B:B)
This always displays FALSE, even when there are duplicates in the list, with corresponding "TRUE" values next to them in column B.
Also, is there a simpler way of solving this problem?
Note: I can get it to work if the single cell result simply does an =OR(B:B) but I still want to know why my first way won't work and if there is an all around simpler way of doing this.
you can use both =unique(A:A) and also =counta(unique(A:A))
note: the A:A is just a dummy array i threw in for example, replace with whatever column you want to refer to.
to get a final yes or no, you could nest it together by putting =if(eq(counta(A:A),counta(unique(A:A))),"No Duplicates", "Contains Duplicates")
I'm not sure whether simpler (I am confident the formula could be simplified!) but copy/pasting the following might be deemed so:
=sum(if(ARRAYFORMULA(countif(A:A,A1:A)>1),1,0))
This should return 0 only if there are no duplicates. If a single entry is repeated twice (three instances) and all other values are unique, the result should be 3.
TRUE is curious as the behaviour is not what I expected and I differs from Excel where true would be converted to TRUE, which normally indicates an automatic change from text to function. I don't have an explanation but it may be connected with lookup because the boolean behaves as I would expect in say an if formula.

SUMIFS Values from non consecutive Column Cells

I need tu sum several cells that are separated one from another, these cells are
C3,F3,I3,L3,O3,R3,U3,X3,AA3,AD3,AG3,AJ3,AM3,AP3,AS3,AV3,AY3,BB3,BE3,BH3,BK3,BN3,BQ3,BT3,BW3,BZ3,CC3,CF3,CI3,CL3,CO3
if this other cells $C$1,$F$1,$I$1,$L$1,$O$1,$R$1,$U$1,$X$1,$AA$1,$AD$1,$AG$1,$AJ$1,$AM$1,$AP$1,$AS$1,$AV$1,$AY$1,$BB$1,$BE$1,$BH$1,$BK$1,$BN$1,$BQ$1,$BT$1,$BW$1,$BZ$1,$CC$1,$CF$1,$CI$1,$CL$1,$CO$1
that are on the same column but different row are >= to certain number given and <= to other given number, but it returns #Value, can somebody help me find out what am I doing wrong?
This is the function i am writing:
=SUMIFS((C3,F3,I3,L3,O3,R3,U3,X3,AA3,AD3,AG3,AJ3,AM3,AP3,AS3,AV3,AY3,BB3,BE3,BH3,BK3,BN3,BQ3,BT3,BW3,BZ3,CC3,CF3,CI3,CL3,CO3),($C$1,$F$1,$I$1,$L$1,$O$1,$R$1,$U$1,$X$1,$AA$1,$AD$1,$AG$1,$AJ$1,$AM$1,$AP$1,$AS$1,$AV$1,$AY$1,$BB$1,$BE$1,$BH$1,$BK$1,$BN$1,$BQ$1,$BT$1,$BW$1,$BZ$1,$CC$1,$CF$1,$CI$1,$CL$1,$CO$1),">="&B55,($C$1,$F$1,$I$1,$L$1,$O$1,$R$1,$U$1,$X$1,$AA$1,$AD$1,$AG$1,$AJ$1,$AM$1,$AP$1,$AS$1,$AV$1,$AY$1,$BB$1,$BE$1,$BH$1,$BK$1,$BN$1,$BQ$1,$BT$1,$BW$1,$BZ$1,$CC$1,$CF$1,$CI$1,$CL$1,$CO$1),"<="&C55)
I'm not 100% certain, but it looks like the problem here is that SUMIFS requires arguments to be expressed in continuous-range form, e.g. A3:CO3. It looks like you're trying to work with every third column in the dataset, yes? As far as I can tell, this is best (only?) done as an array function, so that you can tell it to filter on "every third column."
Enter this in the cell, then press CTRL+SHIFT+Enter (CSE) to evaluate it as an array function:
=SUM(($A$1:$CO$1>=B55)*($A$1:$CO$1<=C55)*(MOD(COLUMN(A3:CO3),3)=0)*(A3:CO3))
You'll also need to hit CSE every time you evaluate or change it. There's a decent tutorial for array functions at https://support.office.com/en-za/article/Guidelines-and-examples-of-array-formulas-7d94a64e-3ff3-4686-9372-ecfd5caa57c7, which may help if you're unfamiliar with them.
