Which programming language is used in Power Query ? Power BI interview questions and answers 015

 Which programming language is used in Power Query ?

The programming language used in Power Query is actually not a single, well-defined language. Instead, it's a hybrid approach that combines elements of several languages:

1. M Formula Language: This is the core language of Power Query. It's a functional, case-sensitive language with a concise syntax and a focus on data manipulation and transformation. M shares some similarities with F#, but it's not a direct subset.

2. Data Definition Language (DDL): Power Query incorporates elements of DDL, specifically for defining tables and columns. This allows you to structure your data and prepare it for analysis.

3. Expression Language: Power Query utilizes an expression language for defining calculations and transformations within your queries. This language borrows concepts from various languages like C# and Visual Basic, making it familiar to users with some programming experience.

4. Scripting Languages (Optional): Power Query allows you to embed code from other scripting languages like Python or R within your queries for specific tasks or integrations. This offers advanced users greater flexibility and customization options.

In summary, Power Query doesn't rely on a single, traditional programming language. It takes a hybrid approach, combining elements of M, DDL, expression languages, and even optional scripting languages, providing a powerful and flexible tool for data manipulation and transformation within the Power BI ecosystem.

If you're interested in learning more about the specific syntax and features of the M language, Microsoft provides comprehensive documentation and resources available online. Additionally, various online communities and forums offer support and guidance for Power Query users of all skill levels.

I hope this clarifies the unique and multifaceted nature of the programming language used in Power Query! Feel free to ask if you have any further questions or need help getting started with Power Query.
