Understanding the ENDS_WITH Function in Looker Studio: Syntax, Functionality, Examples, Limitations, and Usage Tips

Introduction to ENDS_WITH Function in Google Data Studio

The Google Data Studio function "ENDS_WITH" is a versatile command used to evaluate whether a given field or expression concludes with a specified text. This function can be instrumental in a variety of data visualization and analysis contexts, particularly in the areas of data mapping, text analysis, advertisement campaign evaluations, and product sales analysis.

Syntax of ENDS_WITH Function

The syntax of the ENDS_WITH function is relatively straightforward:

ENDS_WITH(X, text)

In this syntax,

represents a field or an expression of any type. The

text

parameter signifies the text to locate within

. Worth noting is that

text

could be a field, expression, or literal value and is case-sensitive.

Functionality of ENDS_WITH Function

The "ENDS_WITH" function operates by scanning characteristic fields or expressions for a specific string of text at their end. If the specified text is found, the function will return a boolean value of 'true.' Otherwise, if the applied field or expression does not conclude with the indicated text, it will return 'false.'

Notably, the sensitivity of the function to the case of the text input enhances its precision. However, it also necessitates a meticulous approach to text inputting to ensure the accurate execution of the function.

Examples of ENDS_WITH Function

Let's envision a scenario where you are analyzing the sales data for an electronic store. You want to distinguish transactions where the product type field ends with the word "Television." Here's how you could use the ENDS_WITH function:

ENDS_WITH(Product_Type, "Television")

In this instance, the data field

Product_Type

is evaluated. For every record ending with "Television", the result will be 'true.' For all others, the outcome will be 'false.'

Another example might involve the analysis of a promotional campaign with different campaign tags. Using the ENDS_WITH function could allow you to single out all campaigns ending with the "Summer":

ENDS_WITH(Campaign_Tag, "Summer")

Again, all records concluding with the "Summer" tag will return 'true,' separating them from the remaining records.

Limitations of ENDS_WITH Function

While the "ENDS_WITH" function is valuable, it also has its limitations. Chiefly, it is sensitive to case and spacing. Therefore, applying the function on a data field with inconsistent text format could result in inaccurate results.

Tips for Use

Keep your data persistent. When using the ENDS_WITH function, ensure the expression or field has a consistent text format. For example, use either all uppercase or all lowercase text.

Overall, dispatching the ENDS_WITH function in Google Data Studio can offer insightful data perspectives, notwithstanding its limitations. Directed and mindful data input use can defy these limitations and conceptualize rewarding data analytics outcomes.
