SUMPRODUCT Vs. Power Query on Mt. KauKau

When faced with tough problems I react in one of three ways

  1. Come up with ingenious solutions
  2. See if a simpler cheat solution is possible
  3. Sit back and ignore

For most problems, I choose 3rd reaction. Occasionally, I rely on 2nd option and very rarely the first one.

When faced with a tricky time sheet summary problem (as outlined above), after initial lethargy I wanted to solve it.

Finding if a cell has 7 in it… [Pattern matching in Excel]

Imagine you work at MI5 as a HR officer. You want to find all agents who have license to kill (licence 7). Your data looks like above.

How would you go about it? 

If you filter the list or use FIND() or SEARCH() formulas, you will end up with agents who also have licenses 77, 17 or not7. So how would you solve this problem?

Of course, you do what any smart person does. You summon Excel and ask it nicely by using some wicked pattern matching logic.

How to find out if a text contains question? [Excel formulas]

On Wednesday (15th July), I ran my first ever webinar, on a topic called, “How to be a BETTER Analyst?” (here is the replay link, in case you missed it).  It was a huge success. More than 1,100 people attend the live webinar and hundreds more watched the replay. As part of the webinar, we had interactive Q&A. Viewers posted their questions and I replied to as many of them as I can.

After the webinar, I wanted to make sure I covered all the questions. So I downloaded the chat history. There were more than 700 messages in it. And I am not in the mood to read line by line to find-out the questions. A good portion of chat messages were not questions but stuff like ‘hello everyone, I am from Idaho’, ‘Wow, Chandoo has beard!”, “Enjoying a beer in Belgium while watching webinar” etc. So I wanted a quick way to flag the messages as question or not.

Who is the most consistent seller? [BYOD]

Who is the most consistent of all?

Imagine you are a category manager at a large e-commerce company. Your site offers various products, but you don’t really make these products. You list products made by other vendors on your site. Every day, these vendors would send you invoices for the amount of product they have sold. Above is a snapshot of such invoices.

Looking at this list, you have a few questions.

  1. Who is the best seller?
  2. Who is the most active seller?
  3. Who is the most consistent seller?
  4. Which seller has fewest invoices?

Let’s go ahead and answer these using Excel. Shall we?

Looking up when the data won’t co-operate (case study)

Occasionally we deal with data that is so uncooperative that we might as well give up and go back to calculators & ledger books.

Recently I found myself in such a situation and learned something new.

Introducing … data that won’t play nice

Drum roll please. Here is a data-set that I got from somewhere.

The problem – build a lookup formula

And the problem. Oh, simple. Write a lookup formula to find how many customer walk-ins we have on any given day.

But how?

Top 10 things I learned using Excel for a decade

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.

Top 10 Formulas for Aspiring Analysts

Few weeks ago, someone asked me “What are the top 10 formulas?” That got me thinking.

If you want to become a data or business analyst then you must develop good understanding of Excel formulas & become fluent in them.

A good analyst should be familiar with below 10 formulas to begin with.
