It is election time in USA, and that means there is a whole lot of drama, discussions and of course data analysis. There are tons of cool visualizations published on all the data. Previously, we talked about “How Trump happened” chart.
Today let’s take a look at the beautiful decision tree chart by NY Times explaining what would happen if each of the 10 swing states vote for Democrats or Republicans. Go ahead and look at that chart. And when you are done playing with it, come back.
My first thought after looking at the chart is: Wow, that is cool. I wonder how we can recreate that experience in Excel?
But as you can guess, making a dynamic tree visualization in Excel is pretty hard. You can create a bubble chart mixed with XY chart to show all the nodes of the decision tree, but as this tree has 2^10 nodes at the bottom level (and 2^11-1 total nodes) our chart would look very clumsy and busy.
So, instead of replicating NY Times chart, why not make our own version that explains the data? You can reuse this idea when visualizing outcomes of several what-if scenarios.Continue »
Anyone who has made a pivot table and their grandma knows that formatting them is a pain. Let’s recap the steps to apply one of the most common formats – currency format.
- Right click on any value field
- Go to Value field settings
- Click on “Number Format” button
- Choose Currency format
- Close the boxes, one after another
Unless you get paid per click, you wont be happy with all those clicks.
Wouldn’t it be cool to just click once and apply most common format to your pivot fields?
Of course you can. Just add oneClickCurrency macro to your personal macros workbook. And then add this to your Home ribbon as a custom button and you have a one click format option for any pivot.Continue »
My twins (Nishanth & Nakshtra) are now almost 7. They are super keen to learn how computers work. So the other day, I showed them Code.org where there are several coding exercises disguised as games. They loved those games … err coding exercises. So that got me thinking… why not make a game in Excel that teaches kids simple programming concepts.
So I built a Snowman & Hot Chocolate Maze game. In this post, let’s understand how to build such a game using Excel VBA.Continue »
Recently I saw an interesting Earth Venus cosmic dance video on Facebook. See the original video below or here.
Although this is not entirely accurate from physics & astronomy perspectives, the dance is a stunning example of patterns that are generated by simple things.
I wanted to recreate this cosmic dance in Excel. How else am I to get my spreadsheet fix on a Saturday?
Here is a quick demo of the final outcome. Read on to learn more about the Earth Venus cosmic dance.Continue »

During last week, an alert reader of our blog, Jørgen emailed me a link to “How Trump happened“. It is an interactive visualization by Wall Street Journal. Jørgen asked me if we could replicate the visualization in Excel. My response: “Making a new chart in Excel? Hell yeah!”

Hello all, prepare to be amazed! Here are 43 creative, fun & informative ways to visualize KPI data.
About a month ago, I asked you to visualize KPI data. We received 65 entries for this contest. After carefully reviewing the entries, our panel of judges have discarded 22 of them due to poor charting choices, errors or just plain data dumps. We are left with 43 amazing entries, each creatively analyzed the data and presented results in a powerful way.

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.

Last night I asked members of our Chandoo.org facebook page to share an Excel problem you are struggling with. Francis asked,
How to save a file as .txt in vba without quotes? When I save as .txt, the file has got quotes inside of it. I used the code Print, but it didnt work because the file loses its delimitation.
Does anyone know how to solve this?
Let’s understand how to save a range as text and overcome the double quote problem.Continue »
Here is a familiar scenario: You are building a dashboard. Naturally, it has a few worksheets – data, assumptions, calculations and output. As you make changes to input data, you constantly switch to calculations (or output) page to check if the numbers are calculating as desired. This back and forth is slows you down.

Filtering a list is a powerful & easy way to analyze data. But filtering requires a lot of clicks & typing. Wouldn’t it be cool if Excel can filter as you type, something like above.
Let’s figure out how to do this using some really simple VBA code.Continue »
In the 39th session of Chandoo.org podcast, Let’s learn about FOR loops.
There is a special giveaway in this podcast. It is a workbook with several FOR loop VBA code examples. Listen to the episode for instructions.

- What is a loop – plain English & technical definitions
- For Loop vs. other kind of loops (While & Until)
- For Next loops
- For Each loops
- Nested For loops
- Special tips on For loops
- Performance issues & infinite loops
- Conclusions & giveaway
Filtering is one of the most used feature in Excel. It is a quick way to take lots of data and narrow down to the subset we want.
But here is one common filtering scenario that is slow as snail.
Imagine you are looking at some sort of sales data (if you can’t imagine, look at the above demo).
Now, you want to filter this list for gender=male, profession=self-employed, product category = chocolates and quantity = 1.
If you use the right click, filter > filter by selected value approach, this will take several clicks.
Wouldn’t it be cool if you can select the entire combination and say filter?
Unfortunately, no such feature exists in Excel.
But you are not aiming to be ordinary in Excel. You are aiming to be awesome in Excel. That means, you don’t take no for answer.
Fortunately, we can quickly write a VBA macro that filters a list by selection. So let’s do that.Continue »
