Data Cleaning in Google Sheets by Ben Collins
Welcome to ” Data Cleaning in Google Sheets ”
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?
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 a series 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.
