What happens to the data types of Query Editor that are not available in the data model while loading data?

When loading data from the Query Editor to the data model in Power BI, any data types that are not supported by the data model are automatically converted to compatible types. This ensures that the data can be loaded successfully without interruption. For instance, if a particular data type like a list or record, which is present in the Query Editor, has no direct equivalent in the data model, Power BI will convert it to a type that can be stored in the model, such as a string or a number.

This conversion is crucial for maintaining the integrity of the data flow and allowing for seamless analysis post load. It facilitates users in focusing on the data analysis instead of getting caught up in type compatibility issues. The other options do not accurately reflect how Power BI handles unsupported types; no errors will be thrown, and data is not entirely ignored or omitted from the model. Hence, the conversion process is a fundamental part of how Power BI manages data types during the loading process.
