Time for some good, old fashioned VLOOKUP love. Let’s say you are writing VLOOKUP()s to get data from an unusually fat table, ie one with heaps of columns. You want to get to lookup ID in first column and get thingamajig in what is that column number. Well, better get counting from 1 and after 19 seconds and lots of squinting you arrive at column number 53 – which has thingamajig.
If this sounds like your VLOOKUP routine, check out these three amazingly simple tips to save some time and effort with your lookups.Continue »

Game for some charting awesomeness?
Off late, I have been doing a lot of data analysis and visualization on performance ratings, salary hike, gender pay equality etc. Today let me share you an awesome way to visualize massive amounts of data.
Scenario: Your organization of 3,686 people recently went thru annual performance ratings & review process. At the end of it, everyone was offered some salary increase (from $0 to $24,000 per year). You have 7 business groups. How do you tell the story of all these salary hikes in one chart?
How about the one above?

Recently, I had to make a bunch of panel charts. After wrangling with Excel (and a tiny bit of VBA) to create them, I wondered if we are suffering needlessly by being too loyal to Excel. I switched to R and could create these panel charts in almost no time (well, first I had to learn how to pivot the data using dplyr). Today, let me share the experience.Continue »
Let’s say you got some text values and want to extract the amounts from them. Something like above.
How to go about it?
We could use a variety of techniques to extract the values.
- Formulas – not easy given the unstructured nature of data. But almost possible. See this for an example.
- VBA – possible, read this forum discussion few ways to do it.
- Power Query – at first glance it might seem tricky, but PQ makes this all too easy. Read on.
Over on Twitter, I came across this beautiful chart, aptly titled – Joyplot. It is the kind of chart that makes you all curious and awed. So I did what any Excel nerd would do. Recreated it in Excel of course. This post takes you thru the process.
Take a look at final outcome above. Read on to learn more.Continue »
When faced with tough problems I react in one of three ways
- Come up with ingenious solutions
- See if a simpler cheat solution is possible
- 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.Continue »
Imagine you are head of human resources at Casual Contracting Co. Every month you hire a lot of temporary staff who spend 1-4 months with CCC before leaving. Sometimes you hire the same people again. Of late, you have noticed a strange process gap. You are paying same person two (or more) salaries.
This is because you are hiring a person for new temp role even before their current one ended. See above picture.
So how to avoid making such hiring boo-boos.
Simple, using Excel of course.Continue »

Imagine you run an office furniture company. You want to stop reordering two brands of furniture – Relaxer (a type of chair) and Boca Top (a type of table). You currently have 20,000 Relaxer chairs and 5,000 Boca Tops. These are valued at $200,000 and $100,000 respectively. When sold, they will yield $100,000 and $25,000 gross profit. You are hoping to sell them off in 2 or 3 years. You forecast that we can sell off these as per some yearly schedule.
You need to analyze this and prepare a cash flow model.
Let’s learn how to answer such open ended questions using various analysis techniques in Excel.Continue »

Few days ago, I saw a beautiful homemade science experiment on Sand Pendulums on Bruce Yeany‘s YouTube channel. Go ahead and check it out. It is a cool project to do with your kids.
I will try this experiment with kids during school term holidays around Easter. But first, I wanted to try the simulation in Excel.

Late. Jayaram, my uncle is also a teacher. When I was a kid, I used to spend a lot of time with him, learning all sorts of things. He taught me chess, maths and so many life lessons. I remember one such lesson very vividly. One day, he asked me to do something. I did it in a very long way. After seeing me struggle for several minutes, he chipped in and showed me how to do it easily. He then said, “when someone asks you where your nose is, you don’t twist arm around your head. You just point to your nose directly.”
The idea is that when you have a direct, simple way to do something, you should use it.
Nose and pivot tables… how are they connected?
We are coming to the point. Read on for full case study and solution.Continue »
