In the 28th session of Chandoo.org podcast, let’s figure out how to express business rules & logic to Excel.
What is in this session?
What good are spreadsheets if they can’t solve business problems?
But we all struggle when it comes to modeling real world business conditions in Excel. For example, if you have below business rule to decide how much discount to offer a customer,
- If the customer bought 3 or more times previously and offer 15% discount
- If the customer bought 1 or 2 times previously AND customer’s age is >40, offer 10% discount
- If the customer visited our New York store between 6PM-9PM offer 5% discount
- Else no discount
How would you go about modeling these in Excel?
That is our topic for this podcast session.
In this podcast, you will learn
- The challenge of modeling business logic & rules in Excel
- My struggles with such formulas in early days
- 4 features of Excel that can help you with this.
- Example business rules & how to write formulas
Today lets learn about Excel CHOOSE() function.
CHOOSE eh? What does it do?
To understand CHOOSE() and appreciate its uses, lets invent an imaginary boos-subordinate pair.
Jasmine is the boss. She is, well, lets call her peculiar. She likes olives, Tuesdays & color Red. She hates potatoes.
Martin is the faithful butler of Jasmine. He is obedient, quirky and tall. He likes lotuses, Fridays & color blue. He hates potassium.
Enter Jasmine’s scarf problem:
Jasmine likes to wear a different colored scarf every weekday. She likes to wear Red colored scarf on Mondays & Tuesdays. She likes to put on the blue polka dot scarf on Wednesdays. On Thursdays, she wears her olive colored scarf. On Fridays & Saturdays, she prefers the lovely orange blue scarf. Sundays are no scarf days.
No wonder she is peculiar.Continue »
Sometime during the 2nd half of 2013, I finished 10 years of Excel usage. In the last 10 years, I completed my studies, got my first job, married, had kids, visited 15 different countries, quit my job to start a business, bought first car, first house, made dozens of new friends, read 100s of books, wrote a book and learned 1000s of new things. And all along, Excel stayed a true companion. Right from MBA entrance exam preparation in 2003 to making my summer internship project reports in 2005 to planning my wedding expenses in 2007 to getting a promotion in 2009 to planning my kids feeding schedule in 2010 to running a successful business in 2014, Excel helped me in every step.
So today, I want to tell you the top 10 things I learned using Excel in last decade. Grab a hot cup of coffee, buckle your belts and get ready for time travel.Continue »

Last Friday, we have learned about an interesting formula – IFERROR Formula using which you can easily handle errors in Excel workbooks.
Quite a few people reading that page asked, “Wow, this is good. But how can I take a sheet full of =IF(ISERROR(…)….) formulas and convert them to =IFERROR()”
There is a different set of folks who asked “Wow, this is good. But quite a few of my colleagues use Excel 2003 and they see a bunch of #NAME errors when I send them an excel workbook with IFERROR formulas. Any help?!?”
I am pleased to announce that I wrote 2 simple macros, iferror2iserror() and iserror2iferror() that would scan formulas in a bunch of selected cells and convert them from IFERROR to ISERROR and vice-a-versa.Continue »
IFERROR() were to be a person, I would hug her so hard that Jo (my wife) would get in to a cat fight with her. I know many a woman (and man) who get in to a fight with Excel formulas often. But thankfully, we avoid that as IFERROR is not a real person. It is, however a darned useful formula.
Since I cannot hug a formula anymore than I can get my son to sit tight, I will go ahead and sing an ode to her, in my style – by writing about how useful and powerful IFERROR formula is.Continue »
