This is an Excel replica of excellent Tableau visual on Tour de France winner data made by Marc Reid.

Last week I saw a stunning visualization on Tour de France using radial charts. I wanted to replicate it in Excel. So here we go.

This is a quick, fun and elegant way to make impressive charts. You can easily create info-graphic style charts in Excel using shape fill technique. Something like this:

Can we predict cricket match score in Excel? Using machine learning, ensemble modeling, multiple regression and Excel formulas we can. This tutorial explains how.

I recently went to Sydney to conduct some training programs on Advanced Excel and Power BI. While I was there, I met my good friend Danielle, who runs Plum Solutions, a financial modeling consultancy & training company. We got talking about various things and the topic eventually turned to “finance people and Power BI”. We […]

Say you want to combine multiple Excel files, but there is a twist. Each file has few tabs (worksheets) and you want to combine like for like, ie , all Sheet1s to one dataset, all Sheet2s to another dataset…

To make matters interesting each sheet has a different format.

What now?

Of course Power Query to the rescue.

Here is a very useful and almost secret Excel tip for you. Imagine you are looking at a big, complex workbook with lots of calculations. You want to understand where everything is pointing to and how the workbook is set up.

You can use trace precedents in Excel to do this. Read this tip to learn how it works.

For every column chart that is done right, there are a dozen that get messed up. That is why lets talk about 5 simple rules for making awesome column charts.

Tip: Same rules apply for bar charts too.

Time for another Excel formula / Power Query challenge. This is based on a common business data analysis problem. Say you have two tables – calls log and office hours. Call log tells when each call is received. Office hours tell us working hours for seven days of the week. We want to know how many calls are outside office hours.

Recently, Microsoft Power BI introduced a very useful visualization, called key influencers visualization. As the name suggests, this is a chart of key parameters that effect a measure or outcome.

For example, you have customer satisfaction rating as a measure. Now you want to know which aspects of your data impact the ratings most? You can create the key influencer visual and Power BI finds all the top ranking influencers (using rules and machine learning).

But can we make it in Excel?

Let’s see…

Imagine you are in a life sustaining planet named Pearth, in another galaxy. One day you got to work, fired up Excel (hey, what else would you use? Excel is the best data software in any galaxy 🙂 ) and started working.

You came across a dataset that need sorting, but left to right – horizontally.

Now what? Do you turn your monitor sideways?

Its Easter time. At Chandoo.org, I have tradition of publishing Easter Egg hunts since 2009. This is the first time our Easter egg hunt is on Power BI. Changing times, eh?

We all know that VLOOKUP can find first match and return the results. But what if you want all the matches? Use this simple trick instead.

Let’s say you manage a fund or charity. You get money from various places and you use that money for various reasons. How do you tell the story of source vs. uses of funds? In this post, let’s review 14 charting options. Source vs. Use of funds – Sample Data for this problem Let’s say […]

Excel has hundreds of formulas. But as a new learner or user, you may want to just focus on top 10 formulas to get the most out of it. Assuming you already know the basics (check out Beginner Excel page if you are complete newbie), here is a list of top 10 Excel formulas for you.

If you want to tell the story of how your business / project / charity / thing is going on, then making a dashboard is the best way to go about it. Dashboards can combine heaps of data, insights and messages in to one concise format that fits on to a desktop or table or mobile screen.

But let’s be honest. Creating them in Excel is a lot of work. Even after spending hours on them, they might still look meh. So, let me share a trick to make your dashboards look snazzy (without compromising on insights per inch).

Create dashboard tiles, something like above.
