Data Cleaning and Pivot Tables in Google Sheets
Transform messy data into robust, usable datasets and gain crucial insights by mastering Google Sheets' most powerful tool, Pivot Tables.
There's a joke in the data community that goes:
"You'll spend 90% of your time cleaning data, and the other 10% of your time complaining about cleaning your data."
Do you deal with badly formatted data that takes you hours to tidy up, preventing you from making progress on your "real" work?
Do you ever find yourself repeating a process manually, like extracting a zip code from an address?
Ever wondered what the heck a Pivot Table is, and why you should care about them?
This course is designed to help you work with messy, real-world datasets, and it's a fit for beginner-to-intermediate level Google Sheets users.
Through four hours of video tutorials, you'll learn techniques and best practices for cleaning data and preparing it for analysis and reporting -- saving you hours of tedious, repetitive work, and helping you get accurate results for your company.
What is Data Cleaning?
Data cleaning is the process of identifying and correcting errors, fixing incomplete data or dealing with irrelevant data in your data sets.
The goal of data cleaning is to create a consistent, clean data set, which gives you the confidence that any subsequent analysis and conclusions you draw will be accurate and thorough.
Why should you care?
Data cleaning is a crucial first step in the data analysis pipeline, yet one that people often overlook.
If you start with "bad" data -- if your data contains duplicate records for example -- you're inevitably going to end up with "bad" conclusions. You might end up double counting revenue, for example, which could have disastrous consequences for your business down the line.
This training course runs through professional techniques and best practices, using formulas and pivot tables, to clean your data, in a Google Sheets setting. Once you've grasped these concepts, you (and your boss!) will feel confident that your conclusions are based on sound data.What this course covers
- Best practices for working with data in Google Sheets.
- All the formulas required for data cleaning.
- Tips and tricks, such as shortcut keys, to make your workflow more efficient.
- Professional techniques for turning messy real-world data into clean, orderly data sets for your analysis.
- Pivot Tables! This course covers Pivot Tables from top-to-bottom. Even if you've never seen a Pivot Table before, you'll soon create cutting-edge ones, using advanced techniques like calculated fields and data extraction with special formulas. I don't think you'll find a more comprehensive course on Google Sheets Pivot Tables anywhere else on the web.
- Two in-depth case studies that show all these techniques being used together, in the wider context of a real-world problem.
- How to analyze your datasets or how to build dashboard reports (see my dashboard course if that's what you want to learn).
- How to use the scripting language, Apps Script, to work with data.
- How to create data visualizations or charts from your data.
What you get with this course:
- Over 4 hours of video tutorials that walk you step-by-step through techniques for cleaning data and using pivot tables.
- Access to all the raw data files used in the examples, copies of the formulas and links to online documentation and other great resources.
- Membership to our dedicated Facebook group, where you can post questions and get answers, share insights and interact with other students.
- All the videos are online and you'll have 24/7 access for life.
Who is this course for?
- Anyone who works with data in Google Sheets -- maybe you're a data analyst, a marketer, an educator, a scientist or someone in between.
- Anyones curious to learn more about working with data and Pivot Tables.
- Anyone who wants to learn best practices and how to be efficient with data.
- Anyone who wants to add new skills that will help you advance your career.
What are the prerequisites?
- A Google account.
- Access to Google Sheets.
- Basic familiarity with Google Sheets and spreadsheets.
- No assumptions are made about prior knowledge of functions or pivot tables -- all the topics are covered comprehensively from scratch, at a comfortable pace.
"Before this course I had used a few simple formulas (okay Average and Sum only) but now I know how to use a vlookup as well as create Pivot Tables.
I’ve been making “Pivot Tables” wrong for years, entering all of the raw data myself. I am now able to make a Pivot Table that will update as needed. I like how Ben shows multiple ways to do data cleaning and why you would choose one method over the other. I enjoyed the case studies at the end because they brought the entire course together.
I will definitely be on the lookout for additional courses from Ben."

"The course starts with a data cleaning section which is highly actionable and relevant to real world data sets that we all work with. My pivot table knowledge was pretty basic before this course and I am confident to say that I am now going to be able to implement them into my data analysis workflow.
This course also took my efficiency to the next level which is exactly what I needed as more of my time and analysis is starting to take place in sheets. I can't recommend this enough."
- John R.
"I am an academic librarian who has worked for years with massive raw data sets and pivot tables, and even gives related presentations at our regional conferences, and yet I learned from Ben's course several very useful tips and techniques that I didn't already know about and that will save me a lot of work.
I plan to recommend it to my colleagues as a very thorough course in getting data ready for the kind of data visualization contexts we need to provide to our decision-makers and stakeholders."
