2019: Week 1

Welcome to your first Preppin' Data challenge.

This week, Jonathan and I would like you to look at taking a simple Excel file on Car Sales and complete the following requirements:


  • Import the starter file (click to open the Google Drive link)
  • Make a date that will work in Tableau Desktop
  • Work out the total car sales per month / per car dealership
  • Retain the car sales per colour columns
  • Export the file 
Due to the way Tableau Prep works, your output:
  • Might not have the same row or column order as our output
  • Will have the same number of columns (7)
  • Will have the same number of rows (48)
For comparison, here's our output file.

For bonus points - you can build a visual analysis of this mocked up data set.

 Created by: Carl Allchin Welcome to a New Year of Preppin' Data. These are weekly exercises to help you learn and develop data preparation skills. We publish the challenges on a Wednesday and share a solution the following Tuesday. You can take the challenges whenever you want and we love to see your solutions. With data preparation, there is never just one way to complete the tasks so sharing your solutions will help others learn too. Share on Twitter, LinkedIn, the Tableau Forums or wherever you want to too. Tag Jenny Martin, Tom Prowse or myself or just use the #PreppinData to share your solutions.  The challenges are designed for learning Tableau Prep but we have a broad community who complete the challenges in R, Python, SQL, DBT, EasyMorph and many other tools.

We will use dif

How to...Handle Free Text

Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in
