Using GPT-4 for Microsoft DAX queries involves understanding that while GPT-4 can assist in generating DAX expressions, it does not replace the need for a deep understanding of the VertiPaq engine and the underlying principles of data modeling and DAX formula language. GPT-4 can provide a starting point for further exploration and refinement for users who may lack that level of expertise.

One way to integrate GPT-4 into Power BI to assist with DAX queries involves four steps:

  1. Set up a ChatGPT API: This can be done using an API provider such as RapidAPI or AWS. Once you have set up your ChatGPT API, you will be given an API key that you will need to use in Power BI.

  2. Create a Custom Function in Power BI: This function calls the ChatGPT API. The function takes a text input (query) and calls the ChatGPT API with the query as a parameter. The function then returns the response from the API, which is the generated DAX expression in plain English.

  3. Test the Custom Function: Before using the custom function in a report, it's important to test it to make sure it's working correctly. To test the function, select “Invoke Custom Function” from the Add Column tab in the Power Query Editor. Then, enter a sample query in the dialog box and click “OK”. If the custom function is working correctly, you should see the generated DAX expression in the new column.

  4. Use the Custom Function in a Report: Once you have confirmed that the custom function is working correctly, you can use it in a report. Simply create a new measure or calculated column and use the custom function as the formula.

Remember that while GPT-4 can help with generating DAX expressions, it's still important to understand the underlying data model and DAX language, as GPT-4's understanding of these is limited to patterns it's learned from its training data.

Unlock the Potential of DAX & GPT4

By asking the right questions and using well-structured prompts in GPT4, you can significantly enhance the DAX results you obtain. This approach enables you to gain deeper insights and improve reporting capabilities using Power BI and Excel. Leverage the available resources, like the downloadable prompts and comprehensive training provided by industry experts. Tap into the full potential of DAX and GPT4 to drive better decision-making for your organization.
