Handling Blanks, Empty Strings, and Zero Values
Handling Blanks
- Replace Missing Values: In Power Query Editor, you can replace blank values with a default value or another meaningful value using the âReplace Valuesâ option. This ensures that your data is complete and doesnât contain unexpected gaps.
- Conditional Columns: You can create conditional columns using Power Query to handle blanks. For instance, if a value is blank, you can replace it with a predefined value.
- DAX Functions: In DAX (Data Analysis Expressions), you can use functions like IF, ISBLANK, and COALESCE to handle blank values in calculations and measures.
Handling Empty Strings
- Replace Empty Strings: Similar to handling blanks, you can use the âReplace Valuesâ option in Power Query Editor to replace empty strings with a suitable value.
- Conditional Columns: Create conditional columns to detect and replace empty strings with a value that makes sense in your context.
- DAX Functions: In DAX, functions like IF and IFBLANK can be used to detect and replace empty strings in calculations.
Handling Zero Values
- Transform in Power Query: In Power Query Editor, you can perform transformations on your data to handle zero values. For example, you can add a small value to zeros or use conditional logic to replace them with other values.
- DAX Functions: In DAX, you can use functions like IF, SWITCH, and IFERROR to handle zero values in calculations and measures. For example, you can replace zeros with NULL or another appropriate value.
- Conditional Formatting: In the Report View of Power BI, you can apply conditional formatting to zero values to make them more visually distinguishable or hide them altogether.
