In this article, we will take a closer look at the ISTEXT function and explain how you can use it in Power BI. We’ll also provide some examples to help you better understand how this function works.
What is the ISTEXT Function in Power BI?
The ISTEXT function is a logical function in Power BI’s DAX language that checks whether a value is a text string or not. It returns a TRUE or FALSE value based on whether the value is a text string or not.
The syntax for the ISTEXT function is as follows:
ISTEXT(❰value❱)
The ❰value❱ parameter is the value that you want to test whether it is a text string or not. This can be a column name, cell reference, or any valid expression that evaluates to a text string.
How to Use the ISTEXT Function in Power BI
To use the ISTEXT function in Power BI, follow these steps:
1. Open the Power BI Desktop application.
2. Select the report that you want to work on.
3. Click on the Modeling tab in the ribbon.
4. Click on the New Column button in the Calculations group.
5. Enter a name for the new column in the formula bar.
6. Type the following formula in the formula bar:
ISTEXT(❰value❱)
Replace ❰value❱ with the name of the column that contains the value that you want to test if it is a text string or not.
7. Press Enter to create the new column.
Once you have created the new column, you can use it in your report to analyze your data. For example, you can filter it by TRUE or FALSE values to see only the text strings in your dataset.
Examples of Using the ISTEXT Function in Power BI
Let's take a look at some examples of how you can use the ISTEXT function in Power BI.
Example 1: Testing if a Value is a Text String
Suppose you have a dataset that contains a column named "Product Name" that contains the names of different products. You want to test whether each value in this column is a text string or not.
To do this, you would create a new column with the following formula:
ISTEXT([Product Name])
This formula checks whether each value in the "Product Name" column is a text string or not and returns a TRUE or FALSE value.
Example 2: Filtering a Column by Text Strings
Suppose you have a dataset that contains a column named "Product Type" that contains the types of different products. You want to filter this column to only show the text strings.
To do this, you would create a new column with the following formula:
ISTEXT([Product Type])
This formula checks whether each value in the "Product Type" column is a text string or not and returns a TRUE or FALSE value. You can then use this column to filter the "Product Type" column by TRUE values to only show the text strings.
The ISTEXT function in Power BI's DAX language is a powerful function that is incredibly useful for identifying text strings in large datasets. By following the steps outlined in this article, you can use the ISTEXT function to test whether a value is a text string or not and filter columns by text strings. Use this function to streamline your analysis and gain valuable insights from your data.
