I have a column of numbers and would like to summarize the result of a formula applied to each row.
For example, if my formula is to square the cell value, in the following table I would like B1 to represent A1^2 + A2^2 + A3^2.
A B
- -
1 14
2
3
Is this possible without creating a column to store the result of the formula for each row before summing (i.e. here, a column containing 1, 4, 9)?
For your example:
=SUM((A1:A3)^2)
But here is the key: enter it as an array formula with Ctrl+Shift+Enter. It will add braces to it and should work.
It should look like this after pressing Ctrl+Shift+Enter:
{=SUM((A1:A3)^2)}
For summing squares of range values, please use this formula =SUMSQ(A2:A80).
So if you have data in Column A, put above formula in cell B2.

Capture adjacent Cell with condition
I have values in A column and corresponding values in B column. I need to capture based on A column value I need to capture adjacent cell value which has no zeros.
Say we have data like:
and we want to retrieve a value from column B that corresponds to alpha in column A, but which is not 0. We can use an array formula with MATCH()to achieve this:
First place:
alpha
in cell D1 and in E1 enter the array formula:
=INDEX(B:B,MATCH(1,(A:A=$D$1)*(B:B<>0),0),1)
Array formulas must be entered with Ctrl + Shift + Enter rather than just the Enter key. If this is done correctly, the formula will appear with curly braces around it in the Formula Bar.
I have a column of numbers. I want to ROUND the numbers in each cell of the column and then take the SUM of the cells.
Of course this can be done by creating another column with the rounded values and then taking its sum.
Say that I have 10 cells in column A. I round them to the nearest 0 using ROUND(A#,0) for A1 through A10. These new values go in B#. Then in B11 I have SUM(B1:B10).
Is there a way to apply the ROUND forumla to each cell in column A within the SUM function so that I do not need to create another column of values?
SUMPRODUCT 'Deals' in Arrays 2
=SUMPRODUCT(ROUND(A1:A10,0))
Just use an array formula - enter with Ctrl + Shift + Enter.
=SUM(ROUND(A1:A10,0))
For example (also shows the rounded numbers in Column B to show it works, or you can see the magic with Formulas > Evaluate Formula.)
I need to find an excel formula that I can use to create a unique list of Item numbers from an array. I do not want to count them I just want to make a list of the Item Numbers. These part numbers are actually Alpha Numeric and can have repeating numbers through out the array multiple times. There is one other catch this list will have empty cells in it and could also be the first record in the array. This data is being pulled into Excel through a Jet report add-in for Excel.
Example: Starting in cell A1..A9
Item No.
<BLANK>
7810042050
783979
7810006045
7810006042
7810006032
<BLANK>
7810006022
7810006032
With values in column A, in C1 enter:
=MAX(A1:A10)
in C2 enter the array formula:
=MAX(IF(A$1:A$10<C1,A$1:A$10,""))
and copy down:
Array formulas must be entered with Ctrl + Shift + Enter rather than just the Enter key.
EDIT#1:
Chris Neilsen has pointed out that the values in column A are actually Text rather than Numeric. To accommodate this, two changes must be made to the formulas:
A1 must be excluded
the alphas must be converted to numeric.
So we will replace the normal formula:
=MAX(A1:A10)
with the array formula:
=MAX(--(A2:A10))
and replace:
=MAX(IF(A$1:A$10<C1,A$1:A$10,""))
with the array formula:
=MAX(IF(--(A$2:A$10)<C1,--(A$2:A$10),""))
and then copy down.
If you have alpha characters in the part numbers you can do this in 2 steps.
Both are array formulas and you need to use Ctrl-Shift-Enter
Col B - sorted list of items in Col A
B2 =IFERROR(INDEX($A$2:$A$10,MATCH(COUNTA($A$2:A2),COUNTIF($A$2:$A$10,"<="&$A$2:$A$10),0),1),"")
Col C - eliminate the duplicates
C2 = IFERROR(INDEX($B$2:$B$10, MATCH(0, COUNTIF($C$1:C1, $B$2:$B$10), 0)),"")
Copy both formulas down.
I tried to combine the two formulas but nesting an array (results in Col B) with varying row ranges did not work out. I could not find a way but the two formulas together will work.
Enter this Formula Array in B2 and copy to B3:B10
FormulaArrays are entered pressing [Ctrl] + [Shift] + [Enter] simultaneously, you shall see { and } around the formula if entered correctly
=IFERROR(
INDEX($A$2:$A$10,
MATCH(1,1+COUNTIF($B1:$B$1,$A$2:$A$10)+(($A$2:$A$10="")*1),0)*1),"")
Suppose I have two columns; A and B. each of which has 50 rows of data. I want to set the value of a third column, C, to the value of A corresponding to, say, the minimum value of B. Can I do this without writing a macro?

Consider in C1:
=IF(B1=MIN(B:B),A1,"")
and copy down:
As you see, no macro is required.
If you have unique values in Column B i.e. there's only one minimum value in the column, you can use following formula. Enter this formula in Cell C1:
=INDEX(A:A,MATCH(MIN(B:B),B:B,0))
Or if you have a fixed range say till row 25, use following formula and change number of rows as required:
=INDEX(A1:A25,MATCH(MIN(B1:B25),B1:B25,0))
If you've repeating minimum value in Column B i.e. minimum value occurs more than one then try this array formula. Enter the formula in Cell C1 and drag it down till the row you want:
=IF(COUNTIF($B$1:$B$25, MIN(B:B))>=ROWS($A$1:A1),INDEX($A$1:$A$25, SMALL(IF(MIN(B:B)=$B$1:$B$25, ROW($B$1:$B$25)-MIN(ROW($B$1:$B$25))+1, ""), ROW(A1))), "")
This is an array formula so commit it by pressing Ctrl+Shift+Enter
Again if you want to use this formula for fixed rows say 25 then use following formula. Change number of rows as accordingly:
=IF(COUNTIF(B:B, MIN(B:B))>=ROWS($A$1:A1),INDEX(A:A, SMALL(IF(MIN(B:B)=B:B, ROW(B:B)-MIN(ROW(B:B))+1, ""), ROW(A1))), "")
Got the tips for array formula from here.
I have a series of numbers
0,1,99,5,5,98,9
They are unsorted and will remain that way.
I cannot use macros.
I want the answer 89 from a formula or an array formula.
89 is the biggest gap (between 9 and 98) in this series when sorted.
I want a formula, no vba, and no sorting my column or row.
I need a formula that sorts the list and subtracts one cell relative to the sorted list and gives the largest difference of the list of differences it creates.
so the list becomes 0,1,5,5,9,98,99
subtracts the current from the previous (na,1,4,0,4,89,1)
and gives me the max 89.
My list is a column of 7 rows.
This formula must be array-entered. In the formula RNG refers to the range where you have entered your numbers, e.g. A1:A7
=MAX(LARGE(RNG,ROW(INDIRECT("1:"&-1+COUNT(RNG))))-
LARGE(RNG,ROW(INDIRECT("2:"&COUNT(RNG)))))
To array-enter a formula, after entering
the formula into the cell or formula bar, hold down
ctrl-shift while hitting enter. If you did this
correctly, Excel will place braces {...} around the formula.
You can see how the formula works by using the Evaluate Formula option on the Formula Auditing tab of the Formulas ribbon.
In brief, the formula works by creating two arrays, sorted in order of size. The "K" value of the LARGE function is an array created by the ROW(INDIRECT sequence. The first returns
{1;2;3;4;5;6}
and the second returns
{2;3;4;5;6;7}
The two arrays of values returned would then be:
{99;98;9;5;5;1}
{98;9;5;5;1;0}
Subtracting one from the other results an array of the differences, and we find the MAX.
MAX(A:A) - LARGE(A:A,2) gives the difference between the largest and second-largest value if your numbers are in column A. Don't put this formula in column A.
Place the values in A1 thru A7 in any order!
In B1 enter:
=RANK(A1,$A$1:$A$7,0)+COUNTIF($A$1:$A1,A1)-1
and copy down thru B7
In C1 enter:
=INDEX($A$1:$A$7,MATCH(ROW(),B$1:B$7,0))
and copy down thru C7
In D2 enter:
=C1-C2
and copy down thru C7
Finally in E1 enter:
=MAX(C:C)
Column B represents the order of the values in column A if they were sorted. Column C contains the values of column A in sorted order. Column D are the differences and E1 gives the desired answer. Here is an example:
