Nobody likes cleaning data, but it's just something that you have to do, right?

This course is Part 5 of our 14 Day Data Cleaning Challenge, where I’m going to teach you a method of data cleaning and preparation that I developed some years ago. It’s been tried and tested by hundreds of people, and it’s been tweaked along the way, improving it so that it’s always up-to-date and always works!

It will help you get your data clean and analysis-ready in minutes rather than weeks.

Yes, you read that correctly – minutes!

The 14D2C2 is a 14 day course that will take you through 1 hour of video lessons and practice sessions every day. In other words, with a 1 hour investment daily for 14 days you will become an expert in data collection, cleaning and preparation!

If you’re ready to take the 14D2C2, email me and I’ll send you the details to get started.
