Unlocking the Power of Wildcards in Excel’s CUBEVALUE Formula
In the realm of data analysis and business intelligence, Excel remains an indispensable tool in the arsenal of data analysts and professionals worldwide. The CUBEVALUE formula, in particular, stands out for its robust capabilities in fetching aggregated data from OLAP (Online Analytical Processing) cubes, which are pivotal in multidimensional analysis. However, the real magic unfolds when we start to combine this powerful function with wildcards, especially when working with data models imported from Power BI into Excel's data model.
What is the CUBEVALUE Formula?
Before we dive into the nuts and bolts of using wildcards, let’s first understand what the CUBEVALUE formula does. At its core, the CUBEVALUE function is designed to retrieve aggregated data from a field in an OLAP cube. It allows users to pull summaries of data based on multidimensional analysis, which is especially useful in scenarios involving complex data sets, like those managed in Power BI.
The Power of Wildcards
Wildcards are symbols that substitute for one or more characters in a string. In the context of data analysis, they are instrumental in filtering data according to a specified pattern. This becomes particularly valuable when you wish to analyze subsets of data based on dynamic or partially known criteria.
Step 1: Crafting a CUBESET Function with Wildcards
In order to employ a wildcard in the CUBEVALUE formula, we must first create a =CUBESET function. This function is used to define a set of data from the cube that meets certain criteria. For our example, let's say we're interested in analyzing data specifically related to India within a Power BI dataset called 'Dashboard_Data'.
Here’s how you can create a CUBESET function in cell A1 of your Excel sheet:
=CUBESET("ThisWorkbookDataModel","Filter([Dashboard_Data].[Level_1].[Level_1].Members, Right([Dashboard_Data].[Level_1].CurrentMember.Name, 6)='_India')")
The essence of this MDX (Multi-Dimensional Expressions) language snippet is to filter members from our dataset where the last 6 characters of the member name equal '_India'. This effectively applies our wildcard condition, enabling us to zero in on data related to India.
Step 2: Using the CUBEVALUE Formula with Your CUBESET
Once you have your CUBESET function ready and referencing the specific data subset of interest, you can then use the CUBEVALUE function to pull aggregated data against this set. For example, if you wish to sum up bookings net amounts for the data subset, the formula would look something like this:
=CUBEVALUE("ThisWorkbookDataModel","[Measures].[Sum of Bookings_Net]",$A$1)
Here, the CUBEVALUE function is referencing the CUBESET we defined in cell A1, effectively pulling the sum of net bookings for our India-related data.
Connecting Excel with Power BI
One of the strengths of using Excel for data analysis is its seamless integration with Power BI. By importing Power BI datasets into Excel's data model, analysts can leverage the powerful data manipulation and visualization capabilities of Excel, augmented by the rich dataset and analytics capabilities of Power BI. This synergy not only amplifies the analytical prowess of Excel but also makes it a more dynamic tool for business intelligence.

Real-world Application
Imagine a scenario where a multinational corporation wants to analyze quarterly sales metrics across different countries in Asia. Using the wildcard strategy in combination with CUBESET and CUBEVALUE functions, the analyst can efficiently compile data for various countries by adjusting the wildcard parameters to fit specific country codes or names. This flexibility allows for rapid, comprehensive analysis without the need for manually sifting through extensive datasets.
Conclusion
Integrating wildcards into the CUBEVALUE formula in Excel opens up a myriad of possibilities for data analysis, especially when coupled with Power BI's advanced data analytics capabilities. By mastering these techniques, data analysts and business professionals can significantly enhance their ability to derive meaningful insights from complex data landscapes.
