Suppose, in Excel, I have a formula =$C$8+1, what must I add to the 1 such that when I drag, it becomes $C$8+2?
Can this be done?
Below is my actual formula.. I wish to increment 1 to 2 such that it becomes =2
IF((NOW()-$C8)=1,"1","0")
Well.. there might be several ways to do it, but the only one I have in the top of my head is using the =ROW() function.
Let's say you're starting the formula at row 5.
=IF((NOW()-$C8)=ROW()-4,"1","0")
The =ROW() will return the row number you currently are (i.e. 5, in this case). Thus, in the first row we'll have =1 (from 5-4) and then =2 (6-4) and so on.
Still, it seems you're comparing dates, right? I'd say you'd need to truncate the values to have a day comparison between them...
=IF((TRUNC(NOW())-TRUNC($C8))=ROW()-4,"1","0")
Hope it helps... or at least give you a path to chose your solution.

I am new to Excel/Google Sheets. I have a difficulty of writing a formula to compare columns as a pair-wise since the formula would be
so big as the day goes.
For example, there're 2 main columns Foo and Bar. I want to find the total number of days that Foo
and Bar are equal so the current formula is =IF(A3 = G3, 1, 0)+IF(B3 = H3, 1, 0)+IF(C3 = I3, 1, 0)+...
But this is kind of tedious because there're ~40 days to compare with. Are there any other alternatives
to write a formula in efficient way? Either Google-App-Scripts or Excel Formula is appreciated.
Cheers!
Give a try on below google-sheet formula. Adjust ranges as you need.
=ArrayFormula(SUM(IF(A3:E3=G3:K3,1,0)))
Assuming that you're needing to get such a total for each row and not merely a single row, try this:
=ArrayFormula(IF(A3:A="",,MMULT(IF(A3:F=G3:L,1,0),SEQUENCE(COLUMNS(A:F),1,1,0))))
Of course you will need to adjust the three ranges to match your own FOO and BAR ranges.
This one formula will produce all results for all rows.
The MMULT function is tricky to explain to those as yet unfamiliar with it. But it's a powerful tool. I'll add a picture I created that may best explain what it does:
By making the second matrix a simple SEQUENCE of 1s as long as the other matrix is wide, we wind up multiplying everything by 1 before adding together. And since anything multiplied by 1 is itself, this combination serves only to do a row-by-row add.
Things to keep in mind with MMULT:
1.) Every cell in every matrix must be a number or it will produce an error.
2.) As in the above formula, there are ways to use either/or conditions to turn every cell in a matrix into a number.
Suppose you have an ordered, indexed list of positive values. These positive values are interrupted by 0 values. I want to determine if a consecutive sub-array exists which is not interrupted by 0 values and whose sum exceeds a certain threshold.
Simple example:
Index, Value
0 0
1 0
2 3
3 4
4 2
5 6
6 0
7 0
8 0
9 2
10 3
11 0
In the above example, the largest consecutive sub-array not interrupted by 0 is from index 2 to index 5 inclusive, and the sum of this sub-array is 15.
Thus, for the following thresholds 20, 10 and 4, the results should be FALSE, TRUE and TRUE respectively.
Note I don't necessarily have to find the largest sub-array, I only have to know if any uninterrupted sub-array sum exceeds the defined threshold.
I suspect this problem is a variation of Kadane's algorithm, but I can't quite figure out how to adjust it.
The added complication is that I have to perform this analysis in Excel or Google Sheets, and I cannot use scripts to do it - only inbuilt formulas.
I'm not sure if this can even be done, but I would be grateful for any input.
Start with
=B2
in c2
then put
=IF(B3=0,0,B3+C2)
in C3 and copy down.
EDIT 1
If you were looking for a Google sheets solution, try something like this:
=ArrayFormula(max(sumif(A2:A,"<="&A2:A,B2:B)-vlookup(A2:A,{if(B2:B=0,A2:A),sumif(A2:A,"<="&A2:A,B2:B)},2)))
Assumes that numbers in column B start with zero: would need to add Iferror if not. It's basically an array formula implementation of #Gary's student's method.
EDIT 2
Here is the Google Sheets formula translated back into Excel. It gives you an alternative if you don't want to use Offset:
=MAX(SUMIF(A2:A13,"<="&A2:A13,B2:B13)-INDEX(SUMIF(A2:A13,"<="&A2:A13,B2:B13),N(IF({1},MATCH(A2:A13,IF(B2:B13=0,A2:A13))))))
(entered as an array formula).
Comment
Maybe the real challenge is to find a formula that works both in Excel and Google sheets because:
Vlookup doesn't work the same way in Excel
The offset/subtotal combination doesn't work in Google sheets
The index/match combination with n(if{1}... doesn't work in Google sheets.
With data in columns A and B, insure column B end with a 0. Then in C2 enter:
=IF(AND(B3=0,B2<>0),SUM(B$1:$B2)-MAX($C$1:C1),"")
and copy downwards:
Column C lists the sums of consecutive non-zeros. In another cell enter something like:
=MAX(C:C)>19
where 19 is the criteria value.
You can avoid the "helper" column by using a VBA UDF.
EDIT#1:
Use this instead:
=IF(AND(B3=0,B2<>0),SUM(B$1:$B2)-SUM($C$1:C1),"")
Thanks to #Tom Sharpe and #Gary's Student for answering the question.
While I admittedly did not specify this in the question, I would prefer to achieve the solution without a helper column because I have to do this operation on 30+ successive columns. I just didn't think it was possible in Excel.
Full credit goes to user XOR LX on the Excelforum for coming up with this solution. It has blown my mind and took me the better part of an hour to wrap my head around, but it is certainly very creative. There is no way I could have come up with it myself. Re-posting it here for the benefit of everyone who is looking into this.
Copy and paste the table from my initial question into an empty Excel sheet such that the headers appear in (A1:B1) and the values appear in (A2:B13).
Then enter this formula as an array formula (ctrl+shift+enter), which gives the max of the sums of all the uninterrupted sub-arrays:
=MAX(SUBTOTAL(9,OFFSET(B2,A2:A14,,-FREQUENCY(IF(B2:B13,A2:A13),IF(B3:B14=0,A2:A13,0))-1)))
Note the deliberate offset to include one additional row below the end of the dataset.
I want to average every 5 rows but also to exclude in the average values that are less than 50. This is the command to average every 5 rows.
=AVERAGE(OFFSET($L$3,(ROW()-ROW($P$2))*5,,5))
This is the command to exclude values less than 50
=AVERAGEIF(L3:L8,">50")
How do I combine those two in one command?
Thanks to a colleague of mine, the following works like a gem.
=IFERROR(AVERAGEIF(OFFSET($L$3,(ROW()-ROW($P$2))*5,,5),">50"),0)
As long as you have Excel 2016, a SUMPRODUCT formula will work.
=SUMPRODUCT((MOD(ROW($A$1:$A100),5)=0)*($A$1:$A$100<50)*$A$1:$A$100)/SUMPRODUCT((MOD(ROW($A$1:$A100),5)=0)*($A$1:$A$100<50)*1)
I assumed your data was in A1:A100 so update that as needed. And in the MOD formula, I used 5 for ever 5th row. If you need to change that, change the 5 in MOD formulas. Lastly, the formula does not include the value 50 since you stated you wanted less than 50.
'Tiny' Differences
Correction
=IFERROR(AVERAGEIF(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5),">50"),0)
Visualize
Let's first visualize what you're actually doing.
For every five rows in column L you are displaying the average of the values, if they are greater than or equal to 50. (in this example) in column G:
For L3:L8 in G2,
for L9:L13 in G3,
for L14:L18 in G4 etc.
Issues
The 1st issue is that the formula is written exclusively for the
2nd row. If you want the first result to be displayed in the first row, the formula will result in a REF! error.
If you want to display the first result in the 1st row you have to
change L$2 to L$1:
=IFERROR(AVERAGEIF(OFFSET(L$3,(ROW()-ROW(L$1))*5,,5),">50"),0)
or for the 3rd row you have to change L$2 to L$3:
=IFERROR(AVERAGEIF(OFFSET(L$3,(ROW()-ROW(L$3))*5,,5),">50"),0)
The 2nd issue is that you are doing something in column L and for
no obvious reason you are using column P in your formula. You could
have used any column Z, AN or CG, but your doing stuff in
column L, so use L.
The 3rd issue is that you have locked the columns $L which means where
ever you put the formula in a single row, the result will be the same. If
you don't lock them, you can copy the formula e.g. to the right and
it will display the results for columns M, N, O etc.:
Other Formulas
=SUM(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5))
=COUNT(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5))
=AVERAGE(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5))
=SUMIF(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5),">50")
=COUNTIF(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5),">50")
AVERAGEIF is available in Excel from version 2007, but for older versions the following formula can be used instead:
=IF(COUNTIF(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5),">"&50)=0,0,SUMIF(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5),">"&50)/COUNTIF(OFFSET(L$3,(ROW()-ROW(L$2))*5,,5),">"&50))
It first checks if COUNTIF results in 0. If it does it displays 0, otherwise it divides SUMIF with COUNTIF.
I have the following table:
and I'd like to have the total for each player but values are every 3 columns.
As you can see from the picture on the bottom part I wrote what manually I should enter.
For player 1
=SUM(D3;G3;J3...)
Player 2
=SUM(D4;G4;J4...)
and so on. What formula should I use to calculate automatically every 3 columns? I know how the MOD works but on the net I found too many examples each one using different methods and none worked so far. Can anyone help me please or point me to the right direction to understand how it works to get this data since I'll be using this a lot (get value from cell every nth column).
thanks
It looks like you should just be using SUMIFS here:
=SUMIFS(3:3,$2:$2,"TOT")
This will sum every value on row 3 (Player 1) where the value in row 2 is "TOT" (every 3rd column). Put this in cell B18 and just copy down in your column B.
Or, in case you change your column labels, you can refer to cell D2 instead of typing "TOT" in the formula:
=SUMIFS(3:3,$2:$2,$D$2)
Try this, it will total all the cells that occur every 3 columns beginning at column D. Z3 can be increased to any column you require:
=SUMPRODUCT((D3:Z3)*(MOD(COLUMN(D3:Z3)-1,3)=0))
The explanation on how it works can be found here (I advise you to bookmark this site for future references. They have many other helpful formulas and functions).
Applying this formula to your reality should be something like this for Player 1 (Not tested. Adjust the ranges as required):
=SUMPRODUCT(--(MOD(COLUMN(D3:Z3)-COLUMN(D3)+1,3)=0),D3:Z3)
I have a list of numbers in a table that I would like to search for and bring back the cell reference of where that number resides. For example the data looks like:
A B C D
1 1 2 3 4
ok it doesn't come out very well as the first one is the row number and then each number below sits under each letter, so C1 would contain '3'....
If I wanted to return the reference number of C1 in a cell I am using the formula of =CELL("address",MATCH(AU14,C1:AG1)) but this just errors. I have tried to put an Index in there too, but I believe that index only works vertically so this bring back a #N/A result.
Can anyone assist as I've wasted too much time on this already! :)
You are indeed missing an INDEX. And INDEX works vertically, horizontally, or both depending on how it's called.
Here is a formula that works for the ranges in the pictures. Should be easy to modify.
Formula in C5
=CELL("address",INDEX(B2:F2,MATCH(C4,B2:F2,0)))
formula
results
To make CELL work you need a cell reference, e.g.
CELL("address",C1)
The trouble is that MATCH just gives you a number, not a cell reference.
Probably the easiest way is to use the ADDRESS function, so a first try might be
=ADDRESS(1,MATCH(AU14,C1:AG1,0)+2)
That would give you the right answer if AU14 contained 3, but isn't considered to be very good because it wouldn't update if you deleted/inserted rows or columns.
A better one would be
=ADDRESS(ROW(C1),MATCH(AU14,C1:AG1,0)+COLUMN(C1)-1)
Then you might want to put in some error handling for the case where it's not found
=IFERROR(ADDRESS(ROW(C1),MATCH(AU14,C1:AG1,0)+COLUMN(C1)-1),"Not found")
