Data cleansing is an important activity within Excel and one that we find ourselves doing day in day out, sometimes without even knowing it.
In this tutorial, you will learn the Top 8 Techniques on Data Cleaning in Excel!
So what is data cleansing?
In the words of Oz du Soleil, Excel MVP, it is like “Hercules being sent out to capture the three-headed dog that guards the entrance to hell!”
So you can see that Oz sees that data cleansing is hard work but one that needs to be done in order to succeed in Excel.
We get thrown data at us from external accounting systems, ERPs or downloads from the company server and most of the time it is not imported in an Excel friendly way. This is where you and I come in to clean the data! You can listen to our podcast episode which was highly entertaining and full of golden nuggets by clicking on below’s image and further down I will show you the My Top Data Cleansing Techniques, which include the ones that Oz uses:
In Excel 2016 it comes built in the Ribbon menu under the Data tab and within the Get & Transform group.
Power Query allows you to extract data from any source, clean and transform the data and then load it to another sheet within Excel, Power Pivot or the Power BI Designer canvas.
One of the best features is to Unpivot Columns.
What that does is transforms columns with similar characteristics (e.g. Jan, Feb, March…) and puts them in a unique column or tabular format (e.g. Month), which then allows you to do further analysis using Pivot Tables which was not possible before unpivoting.
