The Challenge – Sorting
With the post KPI Dashboard – Setting up a Scrollable Table we started a little series of posts on how to create interactive dashboard tables with Microsoft Excel. Showing an extract of a longer list of items and enabling the user to scroll up and down was only the first step. Allowing deeper data analysis on the executive dashboard definitely needs more features. One of the most simple but common techniques for data analysis is sorting. Again we want to enable the user to select the sort criteria and see the results immediately without leaving the dashboard. That is: no need to go to the sheet with the raw data, no need to select ranges, no need to use the sort commands on the Excel menu or ribbon. And of course we want to do this without using VBA.
The Solution
The table on our KPI dashboard looks almost the same as the first one, except the 5 option buttons to select the sort criteria beneath the column headers and the fact that the selected column is highlighted with a darker fill color.
Download the excel file with KPI Dashboards – Scroll and Sort and read below to find how it is done.
The implementation
After some smaller changes on the dashboard, like adding the option buttons, linking them to the same cell and adding simple conditional formatting to the columns, the interesting part is the sorting algorithm on the sheet “calculations”. There are various solutions for sorting in excel using formulas. Most of them are use array formulas, definitely the most elegant way of doing this, but hard to understand. The step-by-step solution with several “help columns” may not be as elegant as an array formula, but it will probably be easier to understand.
This is how the dashboard sorting works:
- Get the relevant data (depending on the sort criteria) by using the function OFFSET (column E)
- Make sure to have a list with unique entries by adding a very small number (column F)
- Sort the list using the function LARGE (column G)
- Use MATCH to find the corresponding position of every value within the unsorted list (column H)
- Put together the whole data table in a sorted form by using the results in column H and OFFSET (columns (J to O)
We are almost there. All we have to do now is changing the starting references in the OFFSET-functions on the dashboard (refer to row 9 on sheet calculation instead of row 5 on sheet data). That is all.
Final remarks
If you are using Excel 2007, you will notice that the conditional formatting of the cells underneath the option buttons will behave somehow strangely when clicking on another button. If you scroll down until the range is out of sight and scroll back again, everything looks fine. This doesn’t happen with Excel 2003, so it seems to be a bug in Excel 2007.

Update on Aug 28, 2008 Justin commented that it would be better if the sort order could be reversed so that you can analyze bottom 10 of any KPI using the dashboard. Robert is kind enough to oblige the request. He sent me another excel with sort enhancement. Download it if you want to see this.

An excellent solution, especially for large data sets.
Another solution without using solver would be to assign the player with the highest score to Team 1, the 2nd to team 2, 3rd to team 3, 4th to team 3, 5th to team 2, 6th to team 1, 7th to team 1 and it continues. This method would end up with a Std Dev of 0.001247219. This works best with a distribution with lower Std Dev for the dataset.
Full Disclosure: this is not my idea, remember reading something a few years ago. Think it may have been Ozgrid
thinking back I now remember why I read about it. About 10 years back I had to distribute around 300 team members into 25-30 odd teams. Used this method based on their performance scores. I used the method I described to do this and the distribution was pretty fair.
Solver would have saved me a ton of time though 🙂
I think the issue with you first Solver approach was that you took the absolute value of the sum of team deviations (which should always be zero except for rounding) instead of the sum of the absolute values (which is a reasonable measure of how unbalanced the teams are).
Here's another simple algorithm you could use: you start from the top (with players sorted from high to low), and at each step allocate the next player to whichever team has the smallest total so far. You can implement it dynamically with some formulas so it will update automatically when the data changes.
If the scores were more widely distributed (so that this might end up with not all teams the same size), you could add a constraint to only pick among the teams which currently have fewest players at each step, or just stop adding to any team when it hits its quota.
When I tried it on the sample, I got the three teams below, with a STDEV of 0.000942809 (i.e. about half of what Solver got to).
Team 1: John, Hugo, Tom, Josh, Eric, Zane, Charles, Andrew
Team 2: Barry, Michael, Kenny, Joe, Xavier, Patrick, Oliver, William
Team 3: Henry, Steven, Ben, Frank, Kyle, Edward, Cameron, Lachlan
Thanks for sharing!
Hi,
I was looking at all the solutions and this is closest to what I intended to do. I am dividing a bunch of players into 3 soccer teams. Players availability is also a factor while deciding the teams.
So the steps the excel needs to do is as follows:
1) In availability column if "yes" go to next
2) Equally divide 'Goalkeepers', 'Strikers', 'Defenders' basis their quality
So the end result gives each 3 teams a balance of players playing at different positions.
Can this be done on Google spreadsheet with only availability as an input from the user and rest calculates by itself.
Sorry for asking such a pointed question, but I have been struggling to find a solution for it for sometime now!
Hi Ishaan,
I am working on a similar problem at the moment, so I am wondering if you ever found a solution and if you are willing to share what you did.
Hi everyone, this is a variation of the famous Knapsack Problem https://en.wikipedia.org/wiki/Knapsack_problem.
I had to use a VBA implementation recently as part of a problem, where we ar trying to allocate teams of an organization into different locations (we are a large company with many different team). The goal was to optimally allocate teams to individual buildings without putting too many teams into one building and not splitting teams apart.
As we had around 400 teams of different sizes, solver couldn't handle it anymore. Luckily there is a Knapsack algorithm implementation in VBA readily available on the internet :).
I also went with a heuristic approach first!
An interesting mathematical solution but what if Eric and Xavier can't stand each other or Patrick is best friends with Steven - the real life problems that effect "even" teams.
@Joe
You can add more criteria like
If Eric and Xavier can't stand each other
=OR(AND(E15=1,E16=1),AND(F15=1,F16=1),AND(G15=1,G16=1))
It must be False
If Patrick is best friends with Steven
=OR(AND(E5=1,E17=1),AND(F5=1,F17=1),AND(G5=1,G17=1))
It must be True
Note that the 2 formulas above are exactly the same
except for the ranges
One must be True = Friends
One must be False = Not Friends
Nice Post!
Just one question What if number of players are not even or equally divisible.
Nice post Hui!
I download your workbook and just try to change in options the Precision Restriction from 10E-6 to 10-8 and the Convergence from 10E-4 to 10E-10. The process take almost the same time, but the results was great.
The standard deviation I got was 0,000471.
Team 1: John, Tom, Kenny, Frank, Eric, Xavier, Edward, Zane
Team 2: Steven, Hugo, Ben, Joe, Josh, Oliver, Cameron, William
Team 3: Barry, Henry, Michael, Kyle, Patrick, Charles, Andrew, Lachlan
Great application of Solver! Thanks for the link!
Great explanation. Well done... However, I tried with 6 teams of 4 players and solver never did finish.
How about vba code for the same data set.
I have 3 column A B C wherein A has text and B has number Wherein C is blank. And in C1 been the header C2 where I want the name to come evenly distributed the number which is in Column B.
My Lastcolumn is 1000.
Sorry if I'm being slow here, but how is 'Team Score' calculated? I've gone through the explanation several times but it seems to just appear.
@Hrmft
This process uses the Solver Excel addin
Solver is effectively taking the model and trying different solutions until it gets a solution that meets all the criteria
Then solver puts the solution into the cell and moves to the next cell
So yes it appears to "just appear"
Hi ! Thank you so much ! Works great 🙂
I cannot get the fourth Equation to work in my excel spreadsheet
You have =($E$2:$G$25=0)+($E$2:$G$25=1)=1 as a SUMIF solution, I have, =($F$2:$H$13=0)+($F$2:$H$13=1)=1 as my solution but it does not work. The only thing I changed is the ranges. Any suggestions?
Thank you.
Jim

Sorry I left some of it out in the previous question,
