The sample data in the image below is collected from a round robin tournament.
There is a Round column,Home team & Away team columns listing who is playing who. A team could be either Home or Away.
For each match in a round (including any "Bye" match) the number of games won for the Home and Away team are recorded in separate columns respectively.
"Ff" = forfeit and has a value of 0. "Bye" result is left blank (at this stage).
Output columns are "Won, Lost, Round".
Required output (shown in the image) is, for any selected team, the top n most-games-won matches (from both Home & Away) sorted in descending order and then the corresponding games lost but sorted in ascending order where the games won are equal. Finally show the rounds where those scores occurred.
These are the challenges I've faced in going from data to output in one step using dynamic array formula:
Collating/Combining the the Win results into 1 column. Likewise the Losses.
Getting the array to ignore blanks or convert "Ff" to 0 without getting #NUM or #VALUE errors.
Ensuring that if I used separate single column arrays the corresponding Loss and Round matched the Win result
Although "Round, Won, Lost" would be acceptable. But I wasn't able to get the Dynamic Array capability to give the required output with this order.
SUMPRODUCT, INDEX(MATCH), SORT(FILTER) functions all hint at a possible one step formula solution.
The solutions are numerous for sorting & filtering where the existing values are already in one column. There was one solution that dealt with 2 columns of values which was somewhat useful How to get the highest values from 2 columns in excel - Stackoverflow 2013
Many other responses are around the use of concatenation, combining/merging array sets, aggregation etc.
My work around solution is to use a Helper Sheet to combine the Wins from the separate results columns and convert blanks & "Ff" to -1. Likewise for Losses. Using the formula for each line
=IF($C5=L$2,IF($F5="",-1,IF($F5="Ff",0,$F5)),IF($D5=L$2,IF($G5="",-1,IF($G5="Ff",0,$G5)),-1))
Example Helper Sheet
To get the final output the Dynamic Array formula was used on the Helper Sheet data
=SORT(FILTER(L$26:N$40,L$26:L$40>=LARGE(L$26:L$40,$J$3),""),{1,2},{-1,1},FALSE)
I'm trying to avoid using pivottable, VBA solutions. Powerquery possible but not preferred.
Apologies for the screenshots but I couldn't work out how to attach the sample spreadsheet file. (Unfortunately Stackoverflow Help didn't help me to/not to do this.)
Based on the comments I changed my answer with a different approach:
=LET(data,A5:F19,
round,INDEX(data,,1),
ha,CHOOSECOLS(data,3,4),
HAwonR,CHOOSECOLS(data,5,6,1),
w,BYROW(ha,LAMBDA(h,IFERROR(XMATCH(L2,h),0))),
clm,CHOOSE(w,{1,2},{2,1}),
srtwon,DROP(REDUCE(0,SEQUENCE(ROWS(data)),LAMBDA(y,z,VSTACK(y,INDEX(HAwonR,z,HSTACK(INDEX(clm,z,),3))))),1),
res,FILTER(srtwon,w),
TAKE(SORT(res,{1,2},{-1,1}),J3))
Old answer:
=LET(data,A5:F19,
round,INDEX(data,,1),
home,INDEX(data,,3),
away,INDEX(data,,4),
HAwonR,CHOOSECOLS(data,5,6,1),
w,MAP(home,away,LAMBDA(h,a,OR(h=L2,a=L2))),
won,FILTER(HAwonR,w),
TAKE(SORT(won,{1,2},{-1,1}),J3))
In your example you selected round 3 for the third result, but that wasn't won, so I guess that was by mistake.
As you can see making use of LET avoids helpers. Let allows you to create names (helpers) that are stored and because you can name them, you can make complex formulas be more readable.
Basically what it does is filter the columns Home, Away and Round (in that order) for either Home or Away equal the team in cell L2. That's sorted column 1 descending and column 2 ascending. Than the number of rows mentioned in cell J3 are displayed from that sorted array.
Here is my solution based on the excellent contribution by #P.b. Thank you much appreciated.
The wins (likewise losses) required mapping the presence, of the team in question, as hT (home team) to the games it won (hG) and adding to that a 2nd mapping of the games it won (aG) when it was the away team (aT). Essentially what was being done on the Helper Sheet. Result was a 1 column array for game wins and a 1 column array for game losses.
In the process I was able to convert the "Ff" text to 0. I attempted without the conversion and it threw an error.
Instead of CHOOSECOLS used HSTACK to create the new array (wins, losses & round) for the FILTER, SORT, TAKE to work on.
If it could be made conciser(?) that is the next challenge. Overall (not just my solution), this exercise has provided greater flexibility and solved the problems stated. I'm happy!
=LET(data,A5:G19,
round,INDEX(data,,1),
hT,INDEX(data,,3),
aT,INDEX(data,,4),
hG,INDEX(data,,6),
aG,INDEX(data,,7),
wins,MAP(hG,
MAP(hT,LAMBDA(h,h=L2)),
LAMBDA(w,t,IF(w="Ff",0,w)*IF(t=TRUE,1,0))) +
MAP(aG,
MAP(aT,LAMBDA(a,a=L2)),
LAMBDA(w,t,IF(w="Ff",0,w)*IF(t=TRUE,1,0))),
losses,MAP(aG,
MAP(hT,LAMBDA(h,h=L2)),
LAMBDA(w,t,IF(w="Ff",0,w)*IF(t=TRUE,1,0))) +
MAP(hG,
MAP(aT,LAMBDA(a,a=L2)),
LAMBDA(w,t,IF(w="Ff",0,w)*IF(t=TRUE,1,0))),
HAwonR,HSTACK(wins,losses,round),
w,MAP(home,away,LAMBDA(h,a,OR(h=L2,a=L2))),
won,FILTER(HAwonR,w),
TAKE(SORT(won,{1,2},{-1,1}),J3))
I have an excel that I'm calculating my Scrum Task's completed average. I have Story point item also in the excel. My calculation is:
Result= SP * percentage of completion --> This calculation is for each row and after that I sum up all result and taking the summary.
But sometimes I am adding new task and for each task I am adding the calculation to the average result.
Is there any way to use for loop in the excel?
for(int i=0;i<50;i++){ if(SP!=null && task!=null)(B+i)*(L+i)}
My calculation is like below:
AVERAGE((B4*L4+B5*L5+B6*L6+B7*L7+B8*L8+B9*L9+B10*L10)/SUM(B4:B10))
First of all, AVERAGE is not doing anything in your formula, since the argument you pass to it is just one single value. You already do an average calculation by dividing by the sum. That average is in fact a weighted average, and so you could not even achieve that with a plain AVERAGE function.
I see several ways to make this formula more generic, so it keeps working when you add rows:
1. Use SUMPRODUCT
=SUMPRODUCT(B4:B100,L4:L100)/SUM(B4:B100)
The row number 100 is chosen arbitrarily, but should evidently encompass all data rows. If you have no data occurring below your table, then it is safe to add a large margin. You'll want to avoid the situation where you think you add a line to the table, but actually get outside of the range of the formula. Using proper Excel tables can help to avoid this situation.
2. Use an array formula
This would be a second resort for when the formula becomes more complicated and cannot be executed with a "simple" SUMPRODUCT. But the above would translate to this array formula:
=SUM(B4:B100*L4:L100)/SUM(B4:B100)
Once you have typed this in the formula bar, make sure to press Ctrl+Shift+Enter to enter it. Only then will it act as an array formula.
Again, the same remark about row number 100.
3. Use an extra column
Things get easy when you use an extra column for storing the product of B & L values for each row. So you would put in cell N4 the following formula:
=B4*L4
...and then copy that relative formula to the other rows. You can hide that column if you want.
Then the overal formula can be:
=SUM(N4:N100)/SUM(B4:B100)
With this solution you must take care to always copy a row when inserting a new row, as you need the N column to have the intermediate product formula also for any new row.
I have a incredibly large spreadsheet that lists details for the computers in my company's inventory. We need to know how many systems we have that are x years old. I was able to sort it by model but because the model names are wildly different it didn't help much. For example, one model name is
13-inch MacBook Pro (2011)
And another is
13-inch Retina MacBook Pro (Mid 2017)
The only constant value in the parentheses is the year at the end. I'm trying to write a formula that will spit out how many of each system there are. We need to know how many are 2011 computers, how many are 2017, etc. We are fine with grouping up "Early, Mid, Late" since we just need a year separation but those terms don't show up in every cell throwing my math off. The rows don't have to be sorted, I just need a count.
My plan of attack would be to first, convert the spreadsheet into a table using Insert > Table... this enables Excel to manage calculating columns for you.
The following assumes that the cell at the top of your list contains the word "Detail".
Second, I would make a new column at the far right with an equation like this:
=mid([#Detail], find(")",[#Detail])-4, 4)
...and I would tune the "Find" function and the "mid" function until it gives me just the year.
Third, sort the entire table by this new column. Tada!
Transfer the data to column A. Cells A1 to A1000 in my Example.
In Enter the years in column C. Cells C2 to C20 in my example.
In cell D2, enter the following Array Formula, and drag it down.
=SUM(IFERROR(IF(VALUE(LEFT(RIGHT($A$1:$A$1000,5),4))=C2,1,0),"-"))
Array Formulas are entered using Control + Shift + Enter, instead of Enter.
The Formula takes the last 5 characters of all entries in the column A. Then it takes the first 4 characters of this new text (to eliminate the closing bracket) and converts the text entries to numerical values. It matches each entry with the year in column C, and totals the matches.
I hope this solves your problem.
