I would like to have a formula in column B, which fetches the data from the last non-blank cell in the range D:H. I have hard-plugged the data in column B to highlight what the desired formula should give me in the end >> the latest value on the timeline.
I have not figured out how to solve this issue using a formula, which would not require a concatenation of IF clauses.
Try, in B2
=index(D2:2,(MATCH(9^9, D2:2,1)))
If you put this formula in column b, it will grab the farthest value to the right, which I think is what you want to do?
=SUBSTITUTE(right(SUBSTITUTE(TEXTJOIN("?",TRUE,D2:H2),"?",REPT("!",50)),20),"!","")

In my Google Sheet, I have 1000+ rows of Date entries. For each Date, I am calculating the Month# and Week# using MONTH() and WEEKDAY() functions respectively.
Here is the link to a sample file: https://docs.google.com/spreadsheets/d/1Af5-pYMFWZ1QtLoaAbPZYMGRvk43JBslUp4KyOFADfA/edit?usp=sharing
Problem Statement:
For all rows which have a unique Month# and Week#, I would like to implement a formula and calculate Output. For example, in my sheet, rows 3 to 6 pertain to Month=1 and Week=4. For this set of 5 rows I am calculating Output column as the subtraction from the first element in that set (ie... C3-$C$3, C4-$C$3, C5-$C$3 so on ). Similarly row 7 to 10 pertain to Month=1 and Week=5, and so I calculate Output
as Data-$C$7 and so on.
How do I implement this structure to calculate Output column on each set of unique Month# and Week# values?
Delete everything from Column F (including the F2 header). Then place the following formula into cell F2:
=ArrayFormula({"Output";IF(C3:C="",,IFERROR(C3:C-VLOOKUP(E3:E,{E3:E,C3:C},2,FALSE)))})
This one formula will create the header and return results for all valid rows.
Since VLOOKUP always finds only the first matching instance of what it is looking up, we can use it to ask that each value in C3:C subtract that first instance of where week-number match for each row.
By the way, although you didn't ask about this, you can also use this type of array formula in Columns D and E, instead of all of the individual formulas you have. To do that, delete everything from Columns D and E (including the headers). Then...
Place the following formula in D2:
=ArrayFormula({"Month #";IF(B3:B="",,MONTH(B3:B))})
... and the following formula in E2:
=ArrayFormula({"Week #";IF(B3:B="",,WEEKNUM(B3:B))})
In Excel/Google Sheets I have found how to sum every N columns on websites such as https://exceljet.net/formula/fixed-value-every-n-columns, but the problem is, from what I can see is that it starts at N column each time. I need something that starts from column 1 and then counts every N columns. like the following:
I need to do this with a formula and not a script.
With Google-Sheets, try:
Formula in M2:
=SUM(QUERY(TRANSPOSE(A2:J2),"Skipping "&L2))
Or, a single dynamic array formula (without dragging):
=INDEX(MMULT(A2:J4*(MOD(COLUMN(A2:J4),L2:L4)=1),SEQUENCE(10,1,1,0)))
Or, more dynamic:
=INDEX(MMULT(A2:J4*(MOD(COLUMN(A2:J4),L2:L4)=1),SEQUENCE(COLUMNS(A2:J4),1,1,0)))
Note: The latter would also work in Excel with slight modifications.
Google sheets formula:
=SUM(FILTER(A2:J2, MOD(A2:J2, L2)=1))
then drag to other cells
or use this array version:
Array version:
=INDEX(TRANSPOSE(MMULT(A2:J4,TRANSPOSE(COLUMN(A2:J4)^0 *
N(MOD(COLUMN(A2:J4), L2:L4)=1)))), ,1)
If you want the cells that were added to be automatically highlighted.
Conditional formatting used on A2:J:
=MOD(COLUMN(), $L2)=1
In M2:
=SUMPRODUCT(A2:J2,N(MOD(SEQUENCE(,COLUMNS(A2:J2),0),L2)=0))
and copied down.
Try this formula on column M:
=SUM((sumif(ArrayFormula(mod((COLUMN(B2:J2)-COLUMN(B2)+1),L2)),0,B2:J2))+A2)
Here's the result on Column M.
Just to break down the code sumif(ArrayFormula(mod((COLUMN(B2:J2)-COLUMN(B2)+1),L2)),0,B2:J2) does the actual calculation with the number of intervals set on Column L but take note that I started at the 2nd column so the range here does not include the first column. The result from this is at the Column O highlighted red as you can see in the screenshot.
At the Column M is the actual solution where I only added the first column by using SUM on top of the previous formula.
I hope my explanation is clear.
Just copy/drag the formula down to each row and it should work.

When using VLookup is there a way to exclude the current row?
I'm trying to determine the following:
If two rows have the same value in column A,
check if they have the same value in column B.
It seems to me that
=exact(B2,vlookup(A2,A:C,2,FALSE))
should be able to do that, the only thing I can't figure out is how to ignore the current row so it doesn't compare itself to itself.
Just starting the vlookup range one row lower than the current row would work, except it's possible that the row with the matching value in column A is either above or below the current row.
Thanks!
If two rows have the same value in column A,
check if they have the same value in column B.
use:
=ARRAYFORMULA(IF(A2:A&B2:B="",,COUNTIFS(
FLATTEN(QUERY(TRANSPOSE(IFERROR(CODE(REGEXEXTRACT(A2:A&B2:B,
REPT("(.)", LEN(A2:A&B2:B)))))),,9^9)),
FLATTEN(QUERY(TRANSPOSE(IFERROR(CODE(REGEXEXTRACT(A2:A&B2:B,
REPT("(.)", LEN(A2:A&B2:B)))))),,9^9)))>1))
Use COUNTIFS instead:
=COUNTIFS(A:A,A2,B:B,B2)>1
You can use the range you want to check for the vlookup
So you can use this query: =exact(A1,vlookup(A1,A1:B4,2,FALSE))
Note: A1:B4 is the range for the vlookup.
For more about vlookup you can check: Link.
Suppose I have only one value anywhere at the cell range C2:Z2, I want that value at B2. What can I do?
I need this solution for all the rows bellow this also. The value might at C:C column at one row, at H:H column at another, that means it is dispersed at the range but there will be only one value at the range in a row.
Place this formula in B2:
=ARRAYFORMULA(TRIM(TRANSPOSE(QUERY(TRANSPOSE(C2:Z), , COLUMNS(C2:Z)))))
The formula above works for any type of values.
If your values are numbers then a simpler formula could be used (MMULT does row wise sum here):
=MMULT(
ARRAYFORMULA(--(C2:Z)),
SEQUENCE(COLUMNS(C2:Z), 1, 1, 0)
)
You can use FILTER()
=FILTER(C2:Z2, NOT(ISBLANK(C2:Z2)))
Reference:
FILTER()
if there will be only one value in the row then a simple sum function will do the job for you. put this in B2 ..
=sum(C2:Z2)
I'm trying to make an array formula which sums up all the rows until this row.
For clarification column a will be the input and column b would be the output. I'm looking for a way to do this with an arrayformula.
a1:1 b1:1a2:2 b2:3a3:5 b3:8a4:3 b4:11
I tried to use =ARRAYFORMULA(SUM(INDIRECT("F1:"&ADDRESS(ROW(),COLUMN(F2:F))))) but this doesn't work.
How about
=arrayformula(sumif(row(A1:A4),"<="&row(A1:A4),A1:A4))
The sumif is evaluated separately for each value in the criteria part so:
In the first row of the output array you have
=sumif(row(A1:A4),"<=1",A1:A4)
giving you just the first row of column A.
In the second row of the output array you have
=sumif(row(A1:A4),"<=2",A1:A4)
giving you the sum of the first 2 rows and so on.
Since OP changed the question with a clarification, A different answer is submitted below:
B1:
=ARRAYFORMULA(MMULT(transpose(A1:A5)*--IF(row(1:5),COLUMN(A:E)<=row(1:5)),ROW(1:5)^0))
