 What language does Power BI use ?

Power BI utilizes several languages for different aspects of its functionality:

1. Data Analysis Expressions (DAX):

  • DAX is the primary language for creating calculated columns and measures within your data model. It allows you to perform complex calculations, aggregations, and data transformations to derive meaningful insights from your data.

2. M language:

  • The M language powers Power Query Editor, which is the tool used for data transformation, cleansing, and shaping before it's imported into your data model. It offers a powerful and user-friendly interface for manipulating data and preparing it for analysis.

3. SQL:

  • While not directly used within Power BI Desktop, SQL plays a crucial role if you're connecting to relational databases. Understanding SQL queries can be helpful for setting up data connections and optimizing data retrieval from various sources.

4. JavaScript:

  • Power BI custom visuals utilize JavaScript for their development. If you're interested in creating or customizing these visuals, knowledge of JavaScript is necessary.

5. Natural Language:

  • Although not a programming language, Power BI's Q&A feature allows you to ask questions about your data using natural language. This feature leverages machine learning and understanding of your data model to dynamically generate insights and visualizations.


  • DAX and M are the core languages you'll encounter most frequently for data analysis and transformation within Power BI.

  • Understanding SQL can be helpful when dealing with relational databases.

  • JavaScript comes into play for custom visual development.

  • Natural language plays a role in interacting with your data through Q&A functionalities.

Remember, you don't necessarily need to be a programming expert to use Power BI effectively. However, having a basic understanding of these languages can enhance your data analysis capabilities and unlock more advanced features of the platform.

Feel free to ask if you have any further questions about specific languages or want to delve deeper into any of them!
