I have four numbers in cells A1-A4
34
45
9
18
And I want to count the sum of all four numbers:
=SUMIF(A1:A4,"<>",A1:A4)
So far so good. How do I change the formula that it only shows the total only if all the numbers (A1:A4) are present. Remove A2 for a blank cell and the total should also be blank. The group of numbers will change per column, so it won't always be four.
Consider
=IF(COUNTBLANK(A1:A4)=0,SUM(A1:A4),"")

I have a value in 11th cell as 35. From 1st cell to 10th cell is empty. I want to fill 1st cell to 10th cell randomly and its sum should be equal to to 11th cell as per in figure. Cell 1 to 5 should have the values between (0-2) and Cell 6 to 10 should have the values between (0-5). Rows 1,2 and 3 filled by manually. I need formula for row 4 which satisfies the conditions and sum should be equal to 20. Guide me the formula in excel, libre-office calc or python. Thanks.
The meaning of the task is not very clear (in fact, why not just fill ten cells with the value 2 and get the desired 20?).
However, the task is not very difficult to solve: The first five cells are filled with =RANDBETWEEN(0;2).
When calculating each next value, you are guided by the already accumulated sum of the previous cells SUM($A1:E1) - that is, fill the next four cells with
=MIN(RANDBETWEEN(0;$K1-SUM($A1:E1));5)
The tenth cell is calculated as the difference between the expected number and the already accumulated sum of the nine previous cells =K1-SUM(A1:I1).
Your screenshot does not show the column names and row numbers - I gave formulas for the range A1:K1, you should adjust them according to your data.
I have a large table of more than 2000 rows, and 5 columns. The values of these cells are either 1 or 0. For each column I want to be able to count the number of 1s in blocks of 20 rows starting from the first row.
Example: For each column count the number of 1s in the first 20 cells (A1:A20), then in cells 21 to 41 (A21:A41), then from 42 to 62 and so on.
Any help is appreciated.
Many thanks,

I have tried various combination of COUNTIF, ROW and OFFSET but did not work. Spent sometime reading various sites for suggestions but could not find the solution.
=COUNTIF(OFFSET(A1,(ROW()-1)*19,0,20,1),1)
is used to count the number of 1s in blocks of 20 rows for column A.
The OFFSET function starts from the cell A1, which is the first cell of the first block of 20 rows.
Then it uses the ROW() function to determine the current row and subtracts 1 to start counting from the first row.
Next, it multiplies the current row by 19 to offset the range by 19 rows for each row.
This is done because the range is starting from A1, which is the first cell of the first block of 20 rows, so it needs to offset by 19 rows to look at the next block of 20 rows.
The OFFSET function then selects a range of 20 rows starting from that point.
In the first row, the formula will look at cells A1:A20, in the second row it will look at cells A21:A40 and so on.
So when you drag the formula down, it will always look at the next block of 20 rows, regardless of where you drag it.
The COUNTIF function then counts the number of 1s in the selected range and returns the result.
I need a formula that uses a series of numbers in one column (numbers 1-21) and returns just a number for every 21 cells.
Example: for every 21 cells return a 1 for every 21 cells return a 2 for every 21 cells return a 3. This should happen up to 650 cells
My formulas do not do this properly, I have to keep changing the # for the formula to work the way I want just looking for a faster solution. This is the formula I am using (=$B$42+2)
Put this in the first column first cell:
=MOD(ROW(A1)-1,21)+1
and this in the second column first cell:
=INT((ROW(A1)-1)/21)+1
And copy both formula down the desired number of rows
If one has the Dynamic array formula SEQUENCE() replace the ROW(A1)-1 with SEQUENCE(650,,0) and Excel will spill the values down automatically 650 rows.
I think is easier you put a filter above the column and filter, for example, the number 1, and put SUM() in the ones, that way you will know how many times go 21 times.
My question is, the column always goes 1-21 or have other numbers if you have other numbers you can put one column that repeats 1-21 in till the end and filter the same way I said before and later you can hide the column.
Hope this helps.🤞
I am trying to count the twelve cells left of my 'total' cell. I am using an offset sum because a new column gets added weekly to the left of 'total' cell. Sum I am using is:
=SUM(OFFSET(Q8,,-12,1,12))
Firstly When I add a new cell the letters change and formula stops working. Second, some of the cells in the twelve have a value of zero, these i need ignoring and counting 12 with values.
Thanks in advance
Sam
12 cells from left of Q8 is range - E8:P8
you can use =SUMIF($E$8:$P$8,">0",E8:P8)
which would solve both problems ie
adding new columns after the total columns
count only cells greater than 0
Maybe you can try this formula to sum "up-to 12 non-zero cells on the left of the totals cell", supposing the latter is at Q8. The formula should move correctly with the cells wjen new cells are inserted on its left.
Q8:
=SUMPRODUCT($A8:P8*(13>COUNTIF(OFFSET(Q8,0,COLUMN($A8:P8)-COLUMN(Q8),
1,COLUMN(Q8)-COLUMN($A8:P8)),">0")))
How to find the invalid records in a column in excel. Invalid records in my example is having special characters not blanks in the columns
E.g : in a column I am having dates from A1: A10 and in A5 & A6 I will have &&&& and %%%%, I want a formula where it should give me a count and result is 8 excluding these two special characters values.
1/1/2013
1/2/2013
1/3/2013
1/4/2013
&&&&&
%%%%%
1/7/2013
1/8/2013
1/9/2013
1/10/2013
Any suggestions please?
This formula will count all cells that don't equal &&&&& or %%%%% including blanks.
=COUNTIFS(A1:A10,"<>&&&&&",A1:A10,"<>%%%%%")
This formula will count all cells that don't equal &&&&& or %%%%% excluding blanks.
=SUMPRODUCT(COUNT(A1:A10)-(COUNTIF(A1:A10,"<>&&&&&")-COUNTIF(A1:A10,"<>%%%%%")))
