Create Data Types with Power Query

Use the Power Query Editor to create your own custom data types from any supported data source. Go to Power Query Editor, select several columns and use the Create Data Type button on the Transform tab of the ribbon to convert them into a new data type. Finally, load the data to the Excel grid, and easily consume and explore your custom data types with interactive data cards and formulas.
