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. 🙂
[PS: if you are new to Chandoo.org, Read this and this before reading this post.]
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.

I see most are saying that array formulas are bad. But I thought that when you use array formulas it grabs all the data at once and performs the calculations in one fell swoop. At least that is how the UDFs that I created work. When I did the time test it was much faster that way. Maybe I'll go back and check to make sure my work is right, but that's what I did.
When I work with array formulas I get a full column of data then work on that column and return a full column of data all at once. Which has shown to be much faster than the alternative.
Anyone have special insights on this?
wow..! thats a pretty impressive list, some real gems in there. I read somewhere the other day that spreadsheet development should be 80% planning and 20% implementation - taking the time to think about layout, how you're going to calculate things and how to structure the data often results in a lot less headaches, and more time for deeper analysis...
Hi Chandoo...
Mixed feeling about this article, while I completely agree with you when you share everyone's points under their name giving credit to contributors, but at the same time I see alot of repeated tips and few those may not be applicable under all cases. (I may have sounded harsh). Some kind of sorting of tips were required than mere 3 categorization. (Tough ask, I know). Some really worthy and awesome tips get lost in occean.
I would have been happy to read only non repititive tips and more like standard chandoo articles.
Well, I have also got two tips (may get lost in the list above), which is not presented above:
1. When using too many pivots - Disable data drilling option. This reduces file size, cache memory and speeds up file.
2. If your macro has used too many files for gathering input, close the file and open. This is also release or kill unwanted space in memory and speeds up. Again this can be achieved by macro to close self file and reopen same file, using timer function.
Please do not count me negative.

Hey, one thing that really speeds up VBA processing of data is to extract ranges into arrays & then working on those arrays. Arrays are a lot faster than using cell offset or any other method for working with a database. After you are done you can also paste the value directly into the range with one single command. This will speed up the macros considerably.
Here is a msdn article with examples in it:
msdn.microsoft.com/en-us/library/aa139976(v=office.10).aspx
Hope this helps
oops, noticed a typo in the tip I posted:
Re directly assigning values in VBA rather than copying & pasting should have read:
Sheet2.Range( "B1:B200 ").Value= Sheet1.Range( "A1:A200 ").Value
not
Sheet2.Range( "B1:B200 ").Value= Sheet1.Range( "A1:A100 ").Value
Corrected with double quotes:
Sheet2.Range("B1:B200").Value= Sheet1.Range("A1:A200").Value

OK, I tested it. My UDFs were faster as array functions (like a couple thousand times). But Excel's built in functions are faster when not doing arrays. Not sure this is the case for all situations.
I can't help but to speak up.
Deleting a PivotTable will not speed up your workbook. It will only reduce the file size. There is zero memory processing for a pivot table if it just sits there.
Instead of destroying the pivot table, why not remove the redundant raw data. That would equally reduce the file size of the workbook, while keeping the pivot table functionality.

Thanks a lot guys for your valuable tips !!
It really worked for me
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
...
...
...
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
I would add:
Application.StatusBar = "Wait a second..."
............
Application.StatusBar = False
Optimizing Speed using Pivot Tables:
If you find that Pivot Tables are becoming sluggish becomes of the sheer volume of tables there is a way to increase performance. By default (xls 2010) pivot tables are designed to autofit the data within the columns as well as preserving formatting. I discovered that unchecking these two options alone will exponentially increase performance.
Here's how to do it:
Right click on your pivot table(s) --->choose 'Pivot Table Options' -->Layout & Format' Tab --->uncheck two boxes at the bottom. Done!
here is my list:
1. Avoid Variants when possible
2. Use long instead of integer
3. Use double instead of single
4. Use booleans as much as possible
5. pull data into arrays, manipulate, then dump back to workbook
6. use .value2 instead of .value if you are looking at strings or numeric values
7. set object variables
dim Wks as Excel.Worksheet
set wks = thisworkbook.Sheets("Sheet1")
8. use with statements...
with wks.cells(x,y)
.value2 = "abcd"
.interior.colorindex=4
with .font
.bold=true
.size =20
.underline=xlunderlinestylesingle
end with
9. use string version of functions (Left$() instead of Left())
10. Test for empty string variables with len() or lenb()...if lenb(String1)=0 then
11. Use the Mid$() function if it is possible instead of split()
12. use the join$() function instead of concatenating strings
13. AscW() to evaluate first characters
14. combine if statements and booleans together
boolean = (lenb(String1) = 0)
16. InStr(), InStrB(), InStrRev() are very fast, InStr() can be used to quickly return a substring occurrence of a string
17. DICTIONARIES!!!!!!!!!!!
18. FileSystemObject
19. My machine runs slightly faster when i fill in all the inputs of a function (instead of InStrB(String1, "abcd"), i use (InStrB(1,String1,"abcd",vbBinaryCompare)
20. Short Circuit If statements: If x = 2 then if y >3 then if z = 5 then b=true or
if x=2 then
if y >3 then
if z=5 then
b=true
c=true
end if
end if
end if
21. use ElseIf
22. my testing indicates ElseIf is slightly faster than a Case Select
23. set strings to empty by: = vbnullstring
24. with application
.screenupdating = false
.displayalerts = false
.enableevents = false
end with
25. UserForms can be very beneficial
26. User-Defined Types are a very neat way to encapsulate data
27. User-Defined Functions are handy, but can increase run-time if called thousands of times
28. if using ElseIfs, nested And Ifs or Select Case statements, put the argument that will occur most frequently at the beginning
29. Looping is not the worst thing...just got to figure out how to do it the most efficiently
30. Use dynamic arrays instead of static arrays
31. if you can figure out Win32 APIs, then they are usually much faster than VBA functions
I worked on a massive spreadsheet and it had become very slow over time as I developed it. I tried stripping down more and more formulas by replacing with pasted values, removed all conditional formatting etc. In the end what finally did the trick was when I removed the last single SUMPRODUCT fomula. It changed the updating time after one change from 7-8 seconds to instantaneously. The SUMPRODUCT I had used the full columns, and if I put it to only look at rows 1-500 it was fine.

TIPS FOR SPEEDING UP EXCEL
(1) Instead of writing a lot of formulas to organise data, you can VLOOKUP() the data in a Pivot table, thereby combining the advantages of Pivot table and VOOKUP().
(2) If you have a range named ‘TotalTaxForTheCurrentFinancialYear’, then it is not compulsory to use this name when making the worksheet. Naming the range as ‘Tax’ or simply ‘T’ will be sufficient. The formula =SUM(T) will be shorter and easier to use.
After completing typing all the formulas, simply edit the name of the range from ‘T’ to ‘TotalTaxForTheCurrentFinancialYear’, in the name box. The formula =SUM(T) will automatically change to =SUM(TotalTaxForTheCurrentFinancialYear).

I don't write many macros and like most of you when doing a recalculation it sometimes takes forever.
I have found that when I looked at my spreadsheet, I could determine which order of calcuations (by column) would produce the least number of iterations. So I wrote a macro to do my calculations on my terms. I picked the order of the columns I wanted to calcuate and it sped up my recalc 5-10X.
I did this so long ago, I believe I used "expression .Calculate".
TIPS TO SPEED UP EXCEL by Vijaykumar Shetye, India
You can view all the formulas in the entire worksheet quickly by pressing [ctrl] and [~] keys simultaneously.
To view results, press the key combination again.

I've had to do a lot of mass calculations for reports etc. that involved repetitive identical, yet complex formulae, which took forever...
I hit on a great time-saver: sort the spreadsheet data; if, for example, the same result was due to a lookup of Hotel Name (A column), Date (B column), and Room Type (F column), the formula (Z column) would be: "=IF(A2&B2&F2=A1&B1&F1,Z1,VLOOKUP(A2&B2&F2,LookUps!A:G,7,FALSE))".
This meant that if the result is the same as the row above, just use the same answer, thus saving loads of time instead of VLOOKUPs. (This is a simplified example, the actual one had INDIRECT(ADDRESS...) in it, too!)
Check files for invalid range names, invalid links and names that aren't needed any longer.
Clearing out some 200 old references in a template made the file open go from 30 seconds to 2.
You can improve the speed by stopping calculation during changing cell value and after that you can enable it. please follow the link.

If you want to highlight the content or result within a cell with colour, use content colour not cell fill colour. This make a large data sheet fast as full colour takes up more resource.
There are already so many useful replies, so don't be mad at me if I repeat someone with the following hints.
While using pivot tables:
1. Link (raw) data from external files, rather then building pivots in the same workbook of the data. => Reduces file size.
2. don't flag "keep source data" in pivot settings. => reduces cache.
Downside is when you want to use slicers, you must allow refresh of the source data and thus people need access to that file.
One extra when using tables above ranges: replace the table header references by cell references in heavy duty formulas. I'm not sure but it seems to be faster and lighter (in #MBs).

In VBA, send out values to the worksheet all together as an array then excel will only re-calculate once rather than each time a cell that is output.
to the guy who said avoid looping in VBA - easier said than done, it's one of the most powerful uses for VBA out there. I'd therefore recomend the half way house and break the loop as soon as you've got what you want, don't let it run until the end. Use While etc.
What I would say on VBA in general is minimise sheet to code interations. Suck all your data into a VBA array THEN do the maths don't use cells themselves as stand alone visual variables.
And to the lady who said it's faster offline - that's because Microsoft are constantly contacting their own website be it security verification and/or update checks
Apply some logic to the order of criteria in sumifs / countifs formula
order the most exclusive criteria first. Once one criteria fails the others do not execute.
Bing AI, given the following query, confirms this: "excel countifs. if one criteria is likely to exclude most of the data range then should this criteria go first in the list to prevent frivilous executions".
