Data type Changes when loading Power BI Data

During the data loading process, Power BI Desktop evaluates the incoming data, and then assigns what it thinks is the correct data type. And in most cases, it makes a good choice. But what if it makes the wrong choice? 

For example, what if one of the columns is a text field made up of the month and the year? Such as December, 2015. Power BI Desktop decides that this is a data field, and changes the value to 12/1/2015. Great if that is what you want.

Editing the data types


During the initial load process, one of the first screens will be the Navigator. On the bottom right, select/click on the Edit button.




This will bring up the Query Editor. The Query Editor is one of the most powerful tools available to the Power BI Desktop, Over time, you'll find this tool more and more useful. On the right side of the Query Editor, locate the Applied Steps section. For this example, the last step the query editor performed was the Change Type.



Simply right click on the Change Type item, and select Delete. Or, simply select/click on the X immediately to the left of the Change Type item. Once the change has been made, the Sales Month column is now back to the value we wanted.




While we are in the Query Editor, lets update the data type for the monetary columns. Holding the Ctrl button, select/click on the monetary columns. On the Data Type combo box, select the Fixed Decimal Number value. 



For our example, the incoming column in Excel was configured as Currency. Once we change the Data Type to Fixed Decimal Number, Power BI recognizes the columns as Currency.


  
When you are finished, select/click the Close & Load button. After loading the data, you can review using the Data Tools. The currency columns are now presented as currency values.

At that point you get the chance to stress over interfaces between the instruments, reports, security (both inward and outside), and the superb, powerful, capricious, and in many cases decimation propensities for the end clients even after you've given total start to finish preparing on the new item.

When loading data into Power BI, data types may change due to automatic detection or mismatches between the source data and Power BI's expected data format. For example, Power BI might interpret a text column as a number if the data contains only digits or mistakenly treat a date column as text. To prevent issues, you can manually set the correct data types in the Power Query Editor before loading the data into the model.

Power BI Desktop often assigns data types automatically, but its assumptions may not always align with your needs, such as interpreting "December, 2015" as a date. You can correct this during data import by using the Query Editor, accessible via the Edit button in the Navigator. In the Query Editor, adjust data types in the Applied Steps section to ensure accurate data representation.
