This is the example sheet.
I'm trying to combine options together but sort out duplicates. Right now, ={"Options";ARRAYFORMULA()} is in v1!A1 because every other formula I've thought of is a lot of IF() functions stringed together going through each and every combination. Is there a better way to do this?
EDIT:
The delimiter is , , not a space.
Difficult to do as an array formula, but a fairly simple pull-down formula would be:
=textjoin(",",true,UNIQUE(transpose(B2:2)))

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))
Can the following formula be simplified as described in the paragraph below it?
=(ABS(D$3-D5)+ABS(E$3-E5)+ABS(F$3-F5)+ABS(G$3-G5)+ABS(H$3-H5)+ABS(I$3-I5)+ABS(J$3-J5)+ABS(K$3-K5))/-1
The problem is that I don't know how many columns I'm going to end up with, and I certainly don't want to continue manually writing each column into the formula. Is there I way to simplify this formula so that every column in a row is calculated?
I've been trying various formulas to no avail, and I can't get usable results via Google searches. I suppose I don't know how to effectively word the question without writing a paragraph.
Thanks, in advance!
Try this one:
=-SUM(ARRAYFORMULA(ABS(D$3:$3 - D5:5)))
GOT IT:
=ArrayFormula(SUM(ABS(D$3:$3-D5:5))/-1)
I've been using Arrayformula to auto-expand formulas (such as "=Left(A2:A,B2:B-1") downward, but I need some help understanding this formula. I've read up on the function itself and browsed many forums about this but I can only find articles explaining how to use this with simple formulas, so I'm going to try to as this as simply as possible here: Is it possible to use Arrayformula to expand formulas downward when the formula uses arrays?
The summary for Arrayformula reads "Enables the display of values returned from an array formula into multiple rows and/or columns and the use of non-array functions with arrays." This was my understanding of how Arrayformula populated a formula into rows automatically. Using this I thought of it as writing a formula that generated an array of formulas, and then splitting them up with Arrayformula. This seems to not work with some formulas such as concatenate, which I will focus my question on. This example is far from my real life problem, but if someone could show me a solution I can apply it elsewhere.
Arrayformula spreadsheet example
Usually when I use Arrayformula with A1:A it would expand the formula through the column, referencing the corresponding rows as it went. With this example I want to have Column C be the concatenated result of columns A and B. Is this possible with Arrayformula? This question is not specific to concatenate, that is just the simplest one that came to mind. Another example would be Countif. Lets say I want to see how many values in the first 5 columns are over 20, and I want that formula to auto populate down, is that possible and if so how would it be done?
Arrayformula second example
P.S. Please don't say copy the formula using the drag handle in the lower right.
I want to change the columns order in google sheet from this:
To this
I know I can do this manually but if I have a lot of columns it's pretty annoying.
There's a simple way to do this?
Thanks in advance!
Building on the idea proposed by Steve in the comment. This works for any arbitrary range, pasted as tested on a range of columns A to D:
=array_constrain(
transpose(sort(transpose({A:D; arrayformula(column(A:D))}), rows(A:D)+1, false)),
rows(A:D),
columns(A:D)
)
Explanation: the 1st argument does the inversion magic by inserting a row of column numbers, transposing, sorting by this row in descending order and transposing back. Then we get rid of this extra row by constraining the result to the original dimensions.
The formula works and is generic enough, but it still feels like a hack. I wonder if someone can come up with a cleaner solution.
How would I go about formatting an arrayformula for this?:
=$D10*(sum($F10:$I10))
I've tried a few different ways but none of them work. I have a bunch of rows with that formula (where of course the row number matches, so for example:
=$D10*(sum($F10:$I10))
=$D11*(sum($F11:$I11))
=$D12*(sum($F12:$I12)) etc...
I need this formula in each row but I'm trying to figure out an arrayformula so that it works when I add or subtract rows.
Thanks for your help!
UPDATE************************************************************************
I've just figured out that =arrayformula(D7:D*(F7:F+G7:G+H7:H+I7:I)) works but I might need to add and subtract columns too. Is there a way to make it work with sum()?
I believe MMULT can be a good alternative:
=ArrayFormula(if(len(D2:D), D2:D*mmult(N(F2:I),transpose(column(F2:I2)^0)),))
Change ranges to suit.
The best way to solve math problem is to split it.
You have two multipliers: D x sum(F:F)
The first task is to make ArrayFormula with D. It's simple:
=ArraFormula(D10:D1000)
And the hard part is to make ArrayFormula with sum. This part was already asked and answered here by AdamL. In your case:
=ArrayFormula(SUMIF(IF(COLUMN(F1:I1),ROW(A10:A1000)),ROW(A10:A1000),F10:I1000))
And your final formula is
=ArrayFormula(D10:D1000 *
SUMIF(IF(COLUMN(F1:I1),ROW(A10:A1000)),ROW(A10:A1000),F10:I1000))
