Larry Thompson

Changing the data type in Power Pivot in Excel is a useful skill that allows you to manipulate and analyze your data more effectively. Whether you want to convert a number to text or transform a date into a different format, Power Pivot provides the necessary tools to accomplish these tasks. In this tutorial, we will explore various techniques for changing data types using Power Pivot in Excel.

Changing Data Types Using the Power Pivot Editor

If you prefer working with an intuitive graphical interface, the Power Pivot Editor is the way to go. To access it, first, make sure you have enabled the Power Pivot add-in in Excel. Once enabled, click on the “Power Pivot” tab in the ribbon and select “Manage” to open the Power Pivot window.

In the Power Pivot window, you will see a list of tables from your Excel workbook. Locate and click on the table that contains the column you want to change the data type for.

Next, locate and click on the header of the column you wish to modify. This will highlight all cells within that column.

To change the data type of a column, right-click on any cell within that column and select “Change Data Type” from the context menu.

A dialog box will appear with a list of available data types. Select your desired data type from this list and click “OK”.

Changing Data Types Using Formulas

If you prefer working with formulas or need more flexibility in changing data types based on specific conditions, you can use DAX (Data Analysis Expressions) formulas in Power Pivot.

To change a data type using formulas, create a new calculated column by clicking on “New Calculated Column” in either the “Home” or “Design” tab of the Power Pivot window.

In the formula bar, enter the desired DAX formula to convert the data type. For example, to convert a numeric column called “Quantity” to text, you can use the following formula:


This formula converts each value in the “Quantity” column to text by concatenating it with an empty string.

Once you have entered the formula, press Enter to apply it. The calculated column will now display the converted values based on your specified data type.

Changing Data Types Using Power Query

If you are working with large datasets or need to perform complex transformations, using Power Query is recommended. Power Query provides a wide range of options for manipulating and shaping your data.

To change a data type using Power Query, click on the “Data” tab in Excel’s ribbon and select “Get Data”. Choose your desired data source from the available options.

In the Power Query Editor window, locate and select the column you wish to modify. Right-click on the selected column and choose “Change Type” from the context menu.

A sub-menu will appear with a list of available data types. Select your desired data type from this list.

If needed, you can also perform additional transformations or apply filters before loading your modified dataset back into Excel.


Changing data types in Power Pivot is a crucial step in analyzing and manipulating your data effectively. Whether you prefer using graphical interfaces or formulas, Power Pivot offers various methods for converting data types with ease. By mastering these techniques, you can enhance your analytical capabilities and gain valuable insights from your Excel datasets.
