Whenever we deal with large amounts of data, one of the goals for analysis is, How is this data distributed?
This is where a Box plot can help. According to Wikipedia, a box plot is a convenient way of graphically depicting groups of numerical data through their five-number summaries: the smallest observation (sample minimum), lower quartile (Q1), median (Q2), upper quartile (Q3), and largest observation (sample maximum)
Today, let us learn how to create a box plot using MS Excel. You can also download the example workbook to play with static & interactive versions of box plots.Continue »

Each new sheet in MS Excel comes up with a 1,048,576 rows and 16,384 columns. While it has a certain binary romantic ring to it (2^20 rows & 2^14 columns), I am yet to meet anyone using even half the number of rows & columns Excel has to offer.
So why leave all those empty rows & columns hanging in your reports?
Would it not look cool if your reports showed only few rows & columns as needed, like this:Continue »
On 14th July, evening 4:51 PM (GMT), Chandoo.org received its 20,000th comment. 20,000!
The lucky commenter was Ishav Arora, who chimed, “Like super computers…Excel is a super calculator!!!!” in our recent poll.
It took us 8 years & 15 days since the very first comment to get here. And it took just 1 year 7 months & 23 days to add the last 10,000 comments (we had our 10,000th comment on 21st November, 2010).
Out of curiosity, I wanted to understand more about these 20,000 comments. So I downloaded our comment database, dumped it in Excel and start analyzing.Continue »

When I was in Perth, I visited Hui’s house one day. Lovely, Hui’s daughter (who is about 14) asked Hui how he knew me. So Hui told that we both share a passion for Excel and that;s how we got to know each other. Then she asked, What is Excel?
At this point, we both tried to explain what Excel is to her in a few ways with no success. Later Hui came up with a brilliant explanation.
He said, Excel has lots of small calculators all interconnected, so that you can do any sort of calculation.
So here is a challenge for you. How would you explain Excel to a small kid (computer literate, but not yet in college).Continue »

Did I tell you I love tennis? Some of my personal heroes & motivators are tennis players. And as you can guess, I admire Roger Federer. Watching him play inspires me to achieve more.

Jo (wife) likes to watch Masterchef Australia, a cooking reality show every night. Even though I do not find contestant’s culinary combats comforting, occasionally I just sit and watch. You see, I like food.
The basic premise of the program is who cooks best in given time. To tell people how much time is left, they use a clock that indicates how much time is left (much like a stop clock, with a small twist).
One day, while watching such intense battle, my mind went
It be cool to make such a clock using hmm… Excel?
While I cannot share my snapper (or pretty much any other food item) with you, I can share my Masterchef style Excel clock with you. So behold,Continue »
We know that using VLOOKUP, we can find a value corresponding to a given item. For example Sales of x. But what if you have multiple sales for each item and you want the last value?
Today lets understand how to find the last date of an activity, given data like above.
