Did you know that MS Excel has a hidden, life altering Easter egg? This is a story of how I found it and discovered joy. Read on.
Almost an year ago, I have quit my job with one of the leading IT companies in the world, to embark on an uncertain but very exciting journey. I have started my own business around MS Excel – creating & selling awesome Excel products & training programs [visit our online store].
This is a continuation of the Chandoo.org Start-up Story posted around the same time last year. Grab a cup of coffee and read it in leisure. Do not expect any Excel tips. 🙂

What is it like to run a small business
When I wanted to leave a stable & well-paying job & start a business several things bothered me. What if my business never picks up? What if I do not generate enough money to sustain my family? What if I grow complacent & make mistakes? What if I get bored or lonely or get demotivated? What if I cannot handle the thousand little things that go in to running a business?
They say, leap and a net will appear. And leap I did. And just as if a switch is turned on, I found answers to all my doubts one by one. I discovered the joy in running a small business around my passion. I made mistakes, but I kept learning. I found help from friends. I made new friendships. I learned how to reduce, automate, outsource areas of work that are not critical. I hired people to help me with customer service & emails. And not one moment, I felt tired, bored or demotivated. In fact, I feel excited every single day about what I am doing.
How is my business doing?
Here is a quick summary of the business:
(April 2010 to March 2011)
- Total paying customers: 2,175 (Repeat customers: 175)
- Revenues: ~$200,000
- Top products – Excel School (743), PM Templates (1148), Dashboard Training (199)
- Consulting clients – Microsoft, Wao Marketing, eNor and more.
- Speaking & Training – Office 2010 Launch Event, International Excel Workshop @ Maldives
- Total Visitors to Chandoo.org – 2.5 Mn
- Visitors who spent more than 15 minutes on site – 787,000
- Number of comments received – 7,790
- Number of articles written – 217
- Press Coverage – MSN, Economic Times etc.
What did I learn in one year of doing this?
Many things. Hardly a week goes by without picking up some new skill or idea. But the most important things have to be,
It is not risky: I had this notion of taking huge risk by leaving a plush job. But then, the risk magically disappeared on day 2. Instead, I see immense opportunity for fun, knowledge, satisfaction and profit. All of which were not possible with my day job beyond certain extent. [Related: Is it scary to start?]
It does not take 80 hours per week: During the first 6 months, I used to work a lot. Most of the time I was inefficient. Then, I analyzed my time (in Excel, what else) and found that I could reduce the number of hours spent on e-mail and other activities to focus on what I love most – Excel, interacting with people and sharing new ideas. Now, I am spending <6 hours per day and I am happy with the results.
You need a supportive family: At least once a day, my son or daughter would walk up to my office-cum-guest-bedroom and knock on the doors, often violently, and scream – “daddy, da.” (meaning, Come out Daddy). Although, my heart would race to go out and hug them, I would say no and continue working.
There were days, when Jo (my wife) would feel lonely as I was locked inside the office room for a product launch or marathon recording session or crafting a dashboard etc.
But, thankfully, I have an understanding wife. So, they would be all smiles when I walk out. Also, I have learned to structure my working hours around my kids sleeping hours. For eg. I would get up at 4AM to do recording.
Saying NO is 100 times tougher than saying YES: While I feel immensely thankful for the growth in my business, it has also bought in a new challenge. There were too many opportunities. So many more than I can handle. I get requests for consulting, training, product development, testing, collaboration and more. Initially I used to say YES to everyone. Soon, I had a pipeline of things to do, with no clear plan on when I will finish everything. Then, I started being picky. I started accepting consulting work for projects which are challenging. I started collaborating with one company at a time. This reduced the workload. But the challenge of saying NO is so much more than YES.
Taking it easy is not so easy: When this blog was my side-business, I used to take it very easily. But during the initial months of making the switch, it was hard for me to take this easily. I would freak-out when my site went down, when a customer dis-liked my product or when I get an email with “Urgent” in the subject.
I learned to slow down things. For eg. I reduced the number of posts per week from 5 to 3. I also roped in more people. Hui, Paramdeep & a few guest authors to write on this blog. Ravindra to help me with emails & customer service. Naturally, this restored my sense of humor and ability to learn new things.
Ask and you shall receive: This is the most important lesson. I used to worry whether anyone would purchase my training or products. But then I realized that by just asking you to purchase, you would consider it. This is how I was able to generate revenues from Excel School, PM Templates and other products.
What next?
I am excited about the way my business has turned out. While I generally avoid from making long-term plans, here are a bunch of things I would continue to do,
- I would like to grow this business slowly and learn new things all along.
- I will continue to share my knowledge, mistakes and ideas with you.
- I will spend a great deal of time with Jo and kids. I love taking long walks with Jo, playing with kids.
- I like connecting with people all around the world and will continue to do so.
- I will continue making awesome products, training programs.
- We (our family) will continue to spend less, live meaningfully and give back a portion of what we make to society.
- I will continue to treat you, my dear reader, as my top-most priority.
Wishing you a happy Easter
I found an Easter egg in Excel. Instead of finding it on Easter day, I find it everyday. And I feel excited, fulfilled, grateful & honored.
I wish you will find your Easter egg. It might be in your profession, hobby, religion or community. I wish you will discover the same joy as I did and continue to spread it.
And if you have already found it, then I feel very happy for you.
Thank you.

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
