DAX, standing for Data Analysis Expressions, is a file extension commonly used by Analysis Services Formula Expressions to represent a collection of functions, operators and constants that can perform a set array of operations in Analysis Services, Power BI Desktop and Power Pivot in Excel.
In the context of Power BI and Excel, DAX file extensions are used as a part of the Power Pivot in Excel and reporting in Power BI. These files are designed to perform powerful aggregations and calculations on data, fostering superior data modeling, data analyses, as well as enhanced reporting. Making use of DAX language in Power BI and Excel, users can create custom measures and calculated columns in tables for advanced data manipulation and analysis.
The DAX language also forms an integral part of SQL Server Analysis Services. It enhances the capabilities of SQL Server Analysis Services, specifically in the creation of tabular data models. In this context, DAX files are used to define custom formulas for calculated columns and measures, enabling more complex and powerful data insights and visualizations.
Considering its particular use-cases, DAX files aren't intended to be opened in the conventional way -- such as double-clicking the file to view its contents. Instead, DAX files are typically loaded into the relevant Microsoft tools (Excel, Power BI, or SQL Server Analysis Services) where they are used within data models or reports.
It is important to note that DAX is not a conventional data file but rather a language that helps unlock powerful possibilities with data analysis and visualization tools within the Microsoft ecosystem. While you cannot open a .dax file directly as you would with standard file formats like .txt or .docx, mastering DAX can substantially boost your data analysis capabilities within Power BI, Excel, and Analysis Services. For further learning, Microsoft provides detailed documentation and resources to master the art of DAX.
