Follow data type conversion best practices
We previously discussed different Power Query types in Chapter 3, Data Preparation in Power Query Editor, in the Introduction to Power Query (M) section. In Chapter 5, Common Data Preparation Steps, we also discussed that data type conversion is one of the most common data preparation steps. In both chapters, we looked at different data types available in Power Query. So, as a data modeler, it is crucial to understand the importance of data type conversion. This section looks at some best practices for data conversion and how they can affect our data modeling.
Data type conversion can affect data modeling
As mentioned, we already discussed the data types in Power Query in Chapter 3, Data Preparation in Power Query Editor, and Chapter 5, Common Data Preparation Steps. However, briefly recalling some points in this section is worthwhile to emphasize the importance of understanding data types in Power Query. In Power Query, we have only...
