Is there an Excel equivalent of the Javascript reduce function? Essentially, I want to apply a function to each cell in a range, and then sum up each result.
The reason I ask is because I have the following sheet:
For each expense, I'm calculating the "change", i.e. the amount needed to round it up to the nearest pound. I'm then summing that at the bottom.
I want to be able to do this without having the extra column and summing those values.
Thanks.
Use SUMPRODUCT(it avoids the need of Ctrl-Shift-Enter) and ROUNDUP(just shorter, personal preference):
=SUMPRODUCT(ROUNDUP(C3:C7,0)-C3:C7)
OK, so I just found out there's something called an array formula where you type your formula and then press Ctrl+Shift+Enter (and it'll put curly brackets around your formula to show that it worked).
So for my example above, I'd type
=SUM(CEILING.MATH(C3:C7)-C3:C7)
Then press Ctrl+Shift+Enter and it'd change it to
{=SUM(CEILING.MATH(C3:C7)-C3:C7)}
and that gives me the £2.11 I'm expecting.

I am trying to produce a count of the number of times different strings come up in an Excel table. An example table, currently in SHEET1, would be this:
I have another table in another spreadsheet where I want to indicate, for each letter on the left in Table 1, how many entries for "za", "zc" or "zd" come up on the right. However, I would only like to only consider one entry of each.
The end result, on row B of SHEET2, would have to be something like this:
At the moment I am using a combination of SUM and COUNTIFS to do the job.
More specifically, applied to the example, I am using the following formula:
=SUM(COUNTIFS(Sheet1!A1:A18,Sheet2!$A1,Sheet1!B1:B18,{"za","zc","zd"}))
The formula is doing some of what is intended. However, it is not counting each entry just one time. Instead, its is counting, for each letter on the left, every entry of "za","zc" or "zd". The table that the formula is returning is as follows:
How can I change the formula so that it does what I intend?
Thank you.
My initial thought would be:
=SUM(MIN (1,COUNTIFS(Sheet1!A1:A18,Sheet2!$A1,Sheet1!B1:B18,{"za","zc","zd"}))
but I’m not where I can test if the MIN will apply properly to the COUNTIFS array of results. ;-)
EDITED: The MIN function is taking minimum of 1 or all of the items in the COUNTIFS array, rather than minimum of 1 and each item in the COUNTIFS array, which is what I was afraid of. Using
=MIN(COUNTIFS(Sheet1!A$1:A$18,Sheet2!$A1,Sheet1!B$1:B$18,"za"),1)+MIN(COUNTIFS(Sheet1!A$1:A$18,Sheet2!$A1,Sheet1!B$1:B$18,"zc"),1)+MIN(COUNTIFS(Sheet1!A$1:A$18,Sheet2!$A1,Sheet1!B$1:B$18,"zd"),1)
will gain the desired results. It is a little clunky, but simpler than an array formula. If you want an array formula, you can use:
=SUM(FREQUENCY(IFERROR(MATCH({"za","zc","zd"},(IF(Sheet1!$A$1:$A$18=$A5,Sheet1!$B$1:$B$18)),0),""),IFERROR(MATCH({"za","zc","zd"},(IF(Sheet1!$A$1:$A$18=$A5,Sheet1!$B$1:$B$18)),0),"")))
This uses the FREQUENCY function to take a set of values and see how many items in another set of values fall within each of the data ranges. Since you need text instead of numbers, we use the MATCH function to find out the first time the value occurs in your list, returning "" with the IFERROR function if it doesn't. (We only need the first occurrence since you don't want to know how many occurrences there are). Since it is text, we use the same input for both arguments for FREQUENCY.
Therefore, if you need to change the values you are looking for or the ranges in which you are searching, make sure to change both! Alternately, you could list the values out somewhere, say in F1:F3, and make a named range for this, another one for A1:A18, and another for B1:B18. Your formula would then look something like this:
=SUM(FREQUENCY(IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),""),IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),"")))
Then you need only change your named range definitions and your formulas would update. :-)
NOTE: Since this is an array formula, you must close out of the cell by pressing CTRL+SHIFT+ENTER rather than only ENTER. When you look at the formula bar, you should see
{=SUM(FREQUENCY(IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),""),IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),"")))}
It does NOT work to enter the curly braces yourself. ;-)
You can use this formula at B1 and fill down:
B1:
=SUMPRODUCT(((Sheet1!$A$1:$A$18=A1)*(Sheet1!$B$1:$B$18= {"za","zc","zd"}))/
COUNTIFS(Sheet1!$A$1:$A$18,Sheet1!$A$1:$A$18,Sheet1!$B$1:$B$18,Sheet1!$B$1:$B$18))
I know that a formula can be applied on a range of cells by utilizing an intermediate column, but can I directly specify a range in a formula somehow?
E.g., is it possible to do something like this, to get the sum of the results of dividing each cell in E12-E26 by each cell in C12-C26:
=SUM(E12/C12:E26/C26)
An answer, either positive or negative, would be accepted.
You can do what you are wanting to do with an Array formula or CSE formula (Different name for the same thing). To do this, enter:
=SUM(E12:E26/C12:C26)
Then, instead of hitting "Enter" on the keyboard use Ctrl+Shift+Enter (CSE). This will put squirrely brackets around the formula and will apply the division to each pair in the range and then sum the results.
You could also use =SUMPRODUCT() for this, which essentially acts like an array formula, but with the Ctrl+Shift+Enter nonsense:
=SUMPRODUCT((E12:E26)/(C12:C26))
Sumproduct is useful since it will do logic inside the parantheses first across an array/range of cells then sum up the results. You can pull of some cool stuff with the formula, but it's also a beast and cat get out of control pretty easily.
I have two sheets with the same line of cells, for example, A1:A5.
I need to check if the value of every cell in Sheet1!A1:A5 is equal to Sheet2!A1:A5 but the hitch is the values will be letters, and all values are different. Simply typing the formula got me a #VALUE! error.
I know I can just write the formula:
=IF(Sheet1!A1=Sheet2!A1;1;0)
and then simply retype it in a number of cells with different values, but I'm looking for a way to shorten the formula.
Any suggestions?
To shorten the formula use array function. With that you will be able to check the whole range at once.
=IF(AND(Sheet1!A1:A5=Sheet2!A1:A5);1;0)
After typing the formula press Ctrl+Shift+Enter instead of just Enter key to confirm array formula.
This one is a little shorter
=(Sheet1!$A1=Sheet2!$A1)
You could use
AND(EXACT(Sheet1!A1, Sheet2!A1), EXACT(Sheet1!A2, Sheet2!A2), EXACT(Sheet1!A3, Sheet2!A3), EXACT(Sheet1!A4, Sheet2!A4), EXACT(Sheet1!A5, Sheet2!A5))
But in the following way:
Have a separate column with the code (let's say, column G)
EXACT(Sheet1!$A1, Sheet2!$A2)
To the column next to that, have a single cell with the code
AND(G1:G5)
Use the AND() function:
IF(AND(Sheet1!A1=Sheet2!A1,Sheet1!A2=Sheet2!A2,Sheet1!A3=Sheet2!A3,Sheet1!A4=Sheet2!A4,Sheet1!A5=Sheet2!A5),1,0).
EDIT
Not realy sure about your aim,
If you want it short because it is too difficult to write the above function, then try the method below:
=IF(CONCATENATE(Sheet2!A1,Sheet2!B1,Sheet2!C1,Sheet2!D1,Sheet2!E1)=CONCATENATE(Sheet1!A1,Sheet1!B1,Sheet1!C1,Sheet1!D1,Sheet1!E1),1,0)
But this is not without catch, it could return false positive. So use it with care. To overcome the false positive, I could only make the formula longer (but still relatively easy to write out).
=IF(CONCATENATE(Sheet2!A1,"|",Sheet2!B1,"|",Sheet2!C1,"|",Sheet2!D1,"|",Sheet2!E1)=CONCATENATE(Sheet1!A1,"|",Sheet1!B1,"|",Sheet1!C1,"|",Sheet1!D1,"|",Sheet1!E1),1,0)
I'm trying to use Indirect with an array formula to get the product of 1 + a cell range (e.g. D5:D7). When I try to use a statement like the one below, I get a #VALUE! error.
={PRODUCT(1+INDIRECT("$D"&K5&":$D"&ROW($A4)))}
In the code above, K5 will contain a number less than Row($A4) (i.e. a number less than 4).
Can someone please suggest a way of accomplishing this?
Thanks very much
This is arguably easier with INDEX function, i.e.
=PRODUCT(1+INDEX(D:D,K5):INDEX(D:D,ROW($A4)))
confirm with CTRL+SHIFT+ENTER
Arguably the easiest way is to simply do:
PRODUCT((A2:A100)+1)
If you want to multiply the (1+cell value) of cells A1 to A100
Sure, it will generate a #VALUE! in the front end but if you then click on the insert formula (the little Fx next to the formula bar) you will see the formula result there.
This value is correct and accurate. I use it all the time for chain-linking returns and can’t be bothered with more complicated formulas.
#Gabs Garcia, your approach is correct, however, I think that instead of everytime checking the value in the Insert Function Menu, it's easier just to use an Array Formula, which works as:
Enter:
=PRODUCT((A2:A100)+1)
Then instead of pressing ENTER, press CTRL+SHIFT+ENTER
Can't believe I don't know this, but is there a way to avoid repeating a formula in an if statement if the logical test is dependent on it?
i.e.
=IF((SUMIFS formula)=0,"",SUMIFs formula)
I want to replace that SUMIFS function in the false scenario with something short that will tell it to just programmatically repeat the formula it originally tested for. Repeating the formula twice has to have detrimental effects on processing speed. Negligible, maybe, but want to go for best-practices here. Thanks.
You can force an error like #DIV/0! and then use IFERROR, e.g.
=IFERROR(1/(1/SUMIFS_formula),"")
You can assign a Name to a formula and use the Name..............See:
Assigning a name to a formula
Relevant excerpt -
For example, let's suppose we frequently use a formula like:
=SUM(A1:A100)-SUM(B1:B100) and this resides in A101 and is copied across many columns on row 101. It would be better in this case to
create a custom formula that does this in each cell on row 101. Here
is how;
1) Select cell A101 (this is vital).
2) Go to Insert>Name>Define and
in the "Names in workbook" box type: SalesLessCosts
3) Now click in
the "Refers to" box and type: =SUM(A1:A100)-SUM(B1:B100) then click
Add.
Now you can replace the formula in cell A101 with: =SalesLessCosts.
You can also copy this across row 101 and it will change its relative
references just as the formula =SUM(A1:A100)-SUM(B1:B100) would. The
reason it does this is all down to the fact we selected A101 before
going to Insert>Name>Define and used relative references in
=SUM(A1:A100)-SUM(B1:B100) when we added it to the "Refers to" box.
If all you need to do is hide zeroes, there is an easy way:
Select all cells where you wish to hide zeroes
Go into Custom Number Formatting
Set format to "General;General;"
The custom formatting has a structure of [positive numbers];[negative numbers];[zeroes]
By making the last part blank you are effectively hiding zeroes, but showing everything else.
The advantage over conditional formatting is that you can use this on any background.
A neat trick which I sometimes use is to hide the cell value completely by using a custom format of ";;;". This way you can put images inside the cells, like the conditional formatting ones, and not see the value at all.
Try using the SUBSTITUTE function like this :
=SUBSTITUTE( VLOOKUP( H4; $D$5:$E$8; 2; 0 ); $H$1; $I$1 )
Here is an example:
Here the formula I don't want to repeat twice is the VLOOKUP function.
The result of VLOOKUP is a string found in another table (ex : "Green").
I want to check if that string matches a specific string value in $H$1 (here, "Yellow").
If it does, SUBSTITUTE replaces it with$I$1 (the error string you want. Here, "FORBIDDEN").
If it doesn't, it displays the VLOOKUP result string (the normal authorized output, like "Green").
This is useful for me because my actual formula is quite long, so I don't want to write it twice.
I also dont want to use two different cells, because I'm already applying this formula on 10 columns, meaning I should add an extra 10 columns to make it work.
In some scenarios, MAX() or MIN() can do a wonderful job.
E.g., something like this:
=IF(SUMIFSformula>0,SUMIFSformula, 0)
Can be shortened to this:
=MAX(0,SUMIFSformula)
The LET formula can be used for this exact scenario. You can define the formula as a variable and then within that same cell you can reference the variable in your formula.
The LET formula format looks like this:
=LET(name,name_value,calculation)
SUMIFS Example
Here's how it would work with your SUMIF example so that you don't have to repeat the formula:
In this screenshot we have an array A1:B7. We want to sum the values (Col B) if the name in ColA is "apple".
For this we have a standard SUMIFS formula of
=SUMIFS(B1:B7,A1:A7,"apple")
The formula is showing in E2. The result is shown in E3.
To put this into the IF statement without having to repeat the formula we can use LET as shown in the screenshot.
We create a variable with the SUMIFS formula as the value of that variable. We then write our IF statement using the variable name instead of rewriting the formula multiple times.
=LET(name,name_value,calculation)
Variable name: sumapples
Variable value: SUMIFS(B1:B7,A1:A7,"apple")
Calculation: IF(sumapples=0,"",sumapples)
Put together in the LET function it looks like this:
=LET(sumapples,SUMIFS(B1:B7,A1:B7,"apple"),IF(sumapples=0,"",sumapples))
This LET function can be used in any Excel formula, and is very useful for shortening long formulas that have repetition.
Optional: Extra complexity
If you want to you can get extra complicated by naming multiple variables.
=LET(name,name_value,name2,name_value2,calculation)
Since Excel 2007, the IFERROR statement does what the OP asked. From the help file:
Description:
Returns a value you specify if a formula evaluates to an error; otherwise, returns the result of the formula. [italics mine]
Syntax:
IFERROR(value, value_if_error)
I've since realised that this was already answered by #barry houdini above.
Here is a hack - depending on whether you are just interested in the displayed value, or whether you need to use the value in another formula:
Put your SUMIF formula in the cell (without the IF part)
Create a conditional formatting rule which sets the font color to the background color when the cell value is 0
And hey presto, you get the desired result.
As I said - it's a hack, but it does prevent the double evaluation.
There is no "clean" solution that I am aware of.
