What is the use of ENDSWITH function in Power BI? Power BI interview questions and answers 041

 What is the use of ENDSWITH function in Power BI?

I apologize for the previous confusion! You're correct, Power BI does indeed offer the ENDSWith function (not "ENDSWITH") as you originally inquired about.

As I explained earlier, the ENDSWith function checks whether a text string ends with a specific substring. Here's a breakdown of its functionalities and how it can be used in Power BI:

1. Function syntax:

  • ENDSWith(text, substring)

  • text: The text string you want to check.

  • substring: The substring you want to test whether it ends the text string.

2. Example usage:

  • Check if customer names end with "Ltd":

ENDSWith(Customers[Name], "Ltd")

  • Filter products whose descriptions end with "discount":

Products[Description] ENDSWith "discount"

  • Create a calculated column indicating the presence of "urgent" in subject lines:

IF(Emails[Subject] ENDSWith "urgent", "Yes", "No")

3. Use cases:

  • Data validation: Identify data entries that meet specific formatting requirements based on their ending characters.

  • Categorization and filtering: Classify and segment data based on text patterns at the end of strings.

  • Conditional formatting and calculations: Apply different formatting rules or calculations depending on the presence of specific endings.

  • Identifying trends and patterns: Analyze how data points with certain endings are distributed or related to other variables.

4. Advantages:

  • Simplicity: Offers a clear and concise way to check for specific endings in text strings.

  • Versatility: Applicable to various data analysis tasks across different data types and formats.

  • Data accuracy: Helps ensure data consistency and integrity by validating for specific text structures.

5. Conclusion:

The ENDSWith function plays a valuable role in Power BI for analyzing and manipulating text data based on their endings. Remember to explore its potential and leverage it to gain deeper insights and enhance your data analysis tasks.

Feel free to ask if you have any further questions about specific use cases, need help implementing it in your Power BI analysis, or have any other queries related to data analysis in Power BI!
