Thank you and welcome.
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.
