Course overview

This course is part of the “Introduction to Data Analysis with Excel” skill path, which we designed for anyone who wants to gain the practical skills in Excel to perform data analysis and visualization, and ultimately help organizations make better informed decisions. We designed it for aspiring data professionals with little experience and learners who use basic Excel in their daily jobs and want to enhance their skills.

Preparing data involves cleaning and organizing. In this course you’ll not only learn how to prepare data with Excel by organizing data into a spreadsheet using worksheets and tables but also how to clean data by removing duplicates and irrelevant data. You’ll also learn how to consolidate the data to prepare it for analysis.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser.

  • Importing data into an Excel spreadsheet from more than one data source

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”

“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”
