Enhancing Power BI Data Analysis with OpenAI API: A Follow-Up Guide


In our previous blog post, we walked you through the process of integrating Power BI with OpenAI’s GPT-4 to generate textual insights. This time, we will dive deeper into leveraging the OpenAI API to analyze data in Power BI and enhance your data-driven decision-making process. By incorporating OpenAI’s natural language processing capabilities, you can extract valuable information from textual data and make informed decisions based on your Power BI analysis.


  1. Familiarity with the previous blog post on integrating Power BI with OpenAI
  2. A Power BI Pro or Premium account
  3. OpenAI API Key
  4. Python and required libraries installed (openai, pandas, powerbiclient)

Note – Please be aware that this solution involves interacting with OpenAI’s API. I encourage users to familiarize themselves with OpenAI’s data usage policy (https://platform.openai.com/docs/data-usage-policy) and take necessary precautions to ensure the privacy and security of their data.

Step 1: Fetch and Process Textual Data

Before analyzing textual data with the OpenAI API, you need to fetch and preprocess it. In this example, we will work with customer reviews data. You can import this data into Power BI from various sources like a CSV file, Excel file, or a database.

  1. Import customer reviews data into Power BI and create a dataset.
  2. Clean and preprocess the data as necessary (e.g., removing duplicates, handling missing values, etc.).

Step 2: Update the Python Script to Analyze Textual Data with OpenAI

  1. Open the Python script you created in the previous blog post (e.g., ‘openai_powerbi_integration.py’) and locate the fetch_openai_data function.
  2. Modify the function to accept the text to be analyzed as an input parameter:
def fetch_openai_data(text):

3. Update the OpenAI API call within the function to perform the desired analysis task. For example, you can modify the prompt to perform sentiment analysis:

def fetch_openai_data(text):
    prompt = f"Analyze the sentiment of the following customer review: '{text}'. Is it positive, negative, or neutral?"
    response = openai.Completion.create(
    generated_text = response.choices[0].text.strip()
    return generated_text

Step 3: Analyze Textual Data in Power BI Using the Updated Python Script

  1. In Power BI, create a new column in the customer reviews dataset to store the sentiment analysis results.
  2. Iterate through the customer reviews and call the fetch_openai_data function for each review. Store the sentiment analysis result in the new column:
for index, row in customer_reviews.iterrows():
    text = row["Review_Text"]
    sentiment = fetch_openai_data(text)
    customer_reviews.loc[index, "Sentiment"] = sentiment

Step 4: Visualize the Analyzed Data in Power BI

  1. In Power BI, create a new report using the updated customer reviews dataset.
  2. Design visualizations to display the sentiment analysis results, such as pie charts, bar charts, or word clouds. You can also create filters to allow users to interact with the data and explore specific segments, such as reviews with positive or negative sentiment.
  3. Save and publish the report to share the AI-enhanced insights with your team.


In this follow-up blog post, we demonstrated how to use the OpenAI API to analyze textual data in Power BI, enhancing your data analysis capabilities. By incorporating the power of OpenAI’s natural language

processing into your Power BI dashboard, you can gain deeper insights and make more informed decisions based on your data.

Remember that this is just one example of how you can integrate OpenAI with Power BI for data analysis. You can customize the Python script and the OpenAI prompt to perform other analysis tasks such as topic extraction, keyword identification, or summarization. The possibilities are vast, and with a little creativity, you can unlock the full potential of combining AI and business intelligence tools to drive your organization’s success.

As you continue exploring the integration of OpenAI and Power BI, always keep in mind the ethical considerations and usage guidelines of AI-generated content. Ensure that the generated insights align with your organization’s values and goals while adhering to responsible AI practices.
