Hell yeah! So I made a spider web generator in Excel. Just use it to make a spooky cob web pattern and add it to your report / dashboard / time sheet or whatever else. Surprise your colleagues.

Find the seals [Excel puzzle]

Find the seals [Excel puzzle]

First a little back story:

Last Friday (on 29th of July), we (Jo, kids & I) went on a day walk to Red Rocks. It is a rugged coastal walk near Owhiro bay in Wellington. It was a windy & cold day. So why did we brave the elements of nature on this 10km walk? To see seals of course. And we did find a few of them. We also caught glimpses of snowy peaks in Southern Island of New Zealand.

3 Seals Excel Puzzle

Now I can’t take you on the same walk thru internet. There is no Excel function that can teleport you from your office (or home) to Owhiro bay. So I made the next best thing.

There are seven pandas hidden in this workbook [Easter Eggs]

It is Easter time again. This year, we drove to my brother’s house in Hyderabad (700 km away from my home) to spend a weekend doing absolutely nothing (we will eat copious amount of food, share family memories, laugh and laze). It is Chandoo.org tradition to share few puzzles during Easter time, a la an Excel themed virtual Easter egg hunt. This year, I have prepared an amazing challenge for you.

Happy Diwali for all our readers – Animated Flower Pot Cracker in Excel for you…

Today is Diwali, the festival of lights. I wish you and your family a happy, bright and prosperous festive time. May your house shower with lots of light, laughter and love.

Diwali is one of my favorite festivals. It is a time when all family members get together, eat delicious food, laugh to hearts content and light up diyas (small oil lamps) to celebrate the victory of good over evil. This year, my kids (who are 6 yrs btw) are very excited about the festival. They are looking forward to lighting up diyas and crackers (fire works).

To celebrate the holiday, I made something for you.

Narrating the story of change using Excel charts – case study

market-share-changes-over-time

Here are three questions you often hear from your boss:

  1. What changes are happening in our business and how do they look?
  2. Do you know how to operate this new coffee machine?
  3. Why does every list has 3 items?

Jokes aside, our urge to find change in environment predates cave drawing, slice bread and Tommy Lee Jones. So, today let’s examine a very effective chart that tells the story of change and re-create it in Excel.

ABC Inventory Analysis using Excel

Published on Oct 1, 2014 in Charts and Graphs, Learn Excel
ABC Inventory Analysis using Excel

ABC analysis is a popular technique to understand and categorize inventories. Imagine you are handling inventory at a plant that manufactures high-end super expensive cars. Each car requires several parts (4,693 to be exact) to assemble. Some of these parts are very costly (say few thousand dollars per part), while others are cheap (50 cents per part). So how do you make sure that your inventory tracking efforts are optimized so that you waste less time on 50 cent parts & spend more time on costly ones?

This is where ABC analysis helps.

We group the parts in to 3 classes.

  • Class A: High cost items. Very tight control & tracking.
  • Class B: Medium cost items. Tight control & moderate tracking.
  • Class C: Low cost items. No or little control & tracking.

Given a list of items (part numbers, unit costs & number of units needed for assembly), how do we automatically figure which class each item belongs to?

And how do we generate above ABC analysis chart from it?

4th of July Fireworks – an Excel animation for you

Published on Jul 4, 2014 in Charts and Graphs, VBA Macros

To all our readers & friends from USA,

I wish you a happy, fun & safe 4th of July.

For the last 4th of July (2013), we (Jo, kids & I) were in USA. We went to Washington DC to meet up a few friends for that weekend. And we had one of the most memorable evenings of our lives when we went to national mall area in the evening to watch beautifully choreographed fireworks. Kids really loved the amazing display of fire-crackers and enthusiasm.

While we all are back in India this time, it doesn’t mean we cant celebrate 4th of July. So I made some fireworks. In Excel of course.

Here is a little Excel animation I made for all of us.

Is this a FIFA worldcup of late goals? Lets ask Excel

Is this a FIFA worldcup of late goals? Lets ask Excel

Just like millions of viewers around the world, I too have been spending hours watching FIFA world cup football matches on TV. I don’t like spending hours watching TV. But when its FIFA world-cup time (which is once every 4 years), I am glued to the idiot box. Blame it on PaWaRa, my school teacher in 8th grade who instilled this passion.

So while watching the match day before yesterday (it was Holland vs. Chile), the commentator said, “This has been a world-cup of late goals” as both teams maintained 0-0 until 77 minute mark when Leroy Fer scored a goal for Holland.

That got me thinking,

Is this really a world-cup of late goals?

But I quickly brushed away the thought to focus on the match.

Later yesterday, I went looking and downloaded all the goal data for 2006, 2010 & 2014 FIFA world-cup matches (2014 data for first 36 matches).

Lets examine the hypothesis “2014 has been a world-cup of late goals”.

Creating Triangular Plots using Excel

Triangular plot…! What is it?

Recently, a Chandoo.org forum member asked this,

‘I want to be able to make a graph that, in some aspects, looks like below, but I have no idea how to do it at all.’

After seeing it, I said to myself in Barney Stinson’s tone, ‘Challenge Accepted!

The final plot looks like above. Read on to learn how this is made.
