This week's #PreppinData challenge is about time reporting for our consultancy business (no, not The Information Lab before my colleagues start to panic!). Can you help us clean up our engagement data to prepare it for analysis? preppindata.blogspot.com/2024/09/2024-w…





When someone writes a review of your book and it's everything you could ever hope for. Jared has managed to capture why and who I wrote Tableau Prep Up & Running for perfectly. Thank you Jared Flores




It's week 43 of the year, so for #PreppinData this week it seems only right to return to the challenges that DS43 created for us earlier in the year! We need to identify the worst selling products in this dataset. Thanks Jess! preppindata.blogspot.com/2024/10/2024-w… Carl Allchin Tom Prowse


Jess is back with part 2 of her #PreppinData challenge this week. MiniBytes would like us to perform some analysis on their returns data and how much they should budget for refunds each month. preppindata.blogspot.com/2024/10/2024-w… Carl Allchin Tom Prowse

This week's #PreppinData is created by a Salesforce Agent rather than Jenny Martin or I. At the #DataFam conference in London, we tasked JP King to use Tableau Agent to create us a challenge and here is how it did. preppindata.blogspot.com/2024/11/2024-w…



This week's #PreppinData was created by Thomas Duong, a recent graduate from the The Data School UK training program. The data comes from Our World in Data and is looking at how Life Expectancy has changed around the world over time. preppindata.blogspot.com/2024/12/2024-w… Carl Allchin Tom Prowse

Hey #PreppinData fans, for 2025 Preppin' challenges will now be released more sporadically throughout the year. There's a bank of over 300 challenges to work through and new tools / languages to learn. Huge thanks to Jenny Martin and Tom Prowse for their years of challenges.

Tableau users looking to strengthen your data prep skills? #PreppinData offers weekly challenges. (preppindata.blogspot.com). I decided to go back and give 2024 week 1 a try. #TableauPrep #DataFam Carl Allchin Jenny Martin Tom Prowse
