If you are into data visualization and reporting, you are likely familiar with Looker Studio, a robust tool that allows users to connect to numerous data sources and create personalised dashboards and reports. Today, we focus on an essential feature of Looker Studio: the Case When statement, our key to unlocking advanced data analysis capabilities.
Understanding the functionality of Looker Studio Case When
CASE WHEN statement in Looker Studio defines conditions and returns a result based on the outcome of those conditions: if they are (or aren't) met. It enables you to create new categories or groupings based on conditional logic, thereby intensifying your data analysis and visualization potential.
Learn to operate Looker Studio Case When
Using the CASE WHEN statement in Looker Studio is straightforward. You commence with the keyword "CASE," followed by one or more "WHEN" clauses, each detailing a particular condition to evaluate. The "THEN" clause pinpoints the result to return if the condition is true. If none of the predefined conditions meet, a default result can be laid out through an optional "ELSE" clause. The statement concludes with the term "END".
For example, you possess a dataset comprising information about website visitors, and you aspire to categorize these visitors based on the device they use. Here's how CASE WHEN comes into play:
In this above example, if a visitor's "device_type" attribute equals "Desktop", the result displays as "Desktop User". If the "device_type" is "Mobile", the result exhibits as "Mobile User". In any case where none of these conditions meet, the output is "Unknown".
Enhance your data analysis capabilities with Looker Studio Case When
CASE WHEN in Looker Studio isn't a one-trick pony. It can also mingle with other functions and calculations within the tool.
