Here is a sneak preview of how much you can accomplish using quick analysis tools in Excel!

We want to focus to show you what Data Cleansing is all about. Data cleansing is an important activity within Excel and one that we find ourselves doing day in day out. This is the prerequisite for you to perform data analysis in Excel.
So what is data cleansing you ask?
We get thrown data at us from external accounting systems, Enterprise Resource Planning systems (ERPs) or downloaded extracts from the company server and most of the time it is not imported in an Excel friendly way.
This drives me nuts! But the beautiful thing with Excel is it provides a multitude of ways with its analysis tools! You can use it for correlation analysis, trend analysis in Excel you name it!
Let us go over them one by one!

Unpivot Data

Power Query is a free add-in created by Microsoft for Excel 2010 (or later) and you can download and install it for Excel 2010 and 2013 here:

In Excel 2016  and newer version it comes built in the Ribbon menu under the Data tab and within the Get & Transform group. So no need to do anything here as you have the awesome Power Query out of the box!
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. You will be amazed on how easy this works!
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.
It is so common to have this format from data extracts. Especially if for example you got a csv file (comma delimited file) downloaded from a table in your database. It is not just conducive to Excel data analysis.
Here is how this is done:

Find & Replace

The Find & Replace feature or CTRL+H shortcut allows you to amend your data in seconds.  Imagine you had thousands of rows of data that was downloaded from an external system with the wrong date.  A simple CTRL+H will save you heaps of time!
Keep this Excel shortcut handy in your pocket so that you can use this anytime when you need to search and clean repetitive errors in your data!

Find & Replace Tips in Excel

Find Errors with Go to Special Constants

Say you have a data set and want to make sure that each column contains what it is supposed to.
For example, say you have a column which contains Dates and you want to check that there are no cells which contain Text.
You can easily check this by highlighting that column and pressing CTRL+G to bring up the Go To dialogue box (or by choosing from the menu Home > Find & Select > Go To…)
Then you need to choose Special > Constants and select the constant that you want to find in your column.
You would be surprised that CTRL+G could be used for this right? I used to think that this is just to jump in navigation over your worksheets!
In our example you will need to only select the Text box and de-select the other boxes and press OK.  This will highlight the cells that contain text and you can begin to format these cells.
Go to special constants

Find Blank Cells In Excel With A Color

In Excel you can have a data set that comes from an external source which isn’t always formatted to your liking.
One of the most common things you may encounter are blank cells in your Excel data which can hinder your analysis, especially if you are using a Pivot Table to analyze the data.
To find these annoying blank cells in Excel you will need to highlight all your data set (CTRL+*) and bring up the Go To shortcut:  CTRL+G > Special > Blanks.
This is another cool trick with CTRL+G! Imagine it doing the dirty work for you to find all the blank cells, then highlighting them for you so that you can quickly make the manual fixes.
Then you can fill in the blank cells with a color red and filter by that same color to drill down to these blank cells and take some formatting action.

Text To Columns: Dates

Sometimes “Date” values are downloaded as “Text”, so you cannot sort in the periodic date format.
No worries!  Text to Columns to the rescue! It will do the conversions for you.
Do take note that if the dates are not converting properly after you do the Text to Columns, it may be that your computer’s Region formats need changing.
Go to the Region settings in your Control Panel and make sure that the Short Date is in this format: dd/MM/yyyy
