How to Integrate OpenAI with Microsoft Excel

January 24, 2025

Learn how to seamlessly integrate OpenAI with Microsoft Excel to enhance your data analysis and automation skills. Step-by-step guide included.

How to Connect OpenAI to Microsoft Excel: a Simple Guide

 

Set Up OpenAI API Key

 

  • Go to the OpenAI Platform to create an account or log in.

    •  

  • Navigate to the API section to obtain your API key. This key will be used to authenticate your requests to OpenAI.

 

Enable Developer Tools in Excel

 

  • Open Microsoft Excel and access the Excel Options by clicking on "File" > "Options".

    •  

  • Select "Customize Ribbon" and enable the "Developer" option. This adds the Developer tab to Excel's toolbar, allowing you to insert macros and scripts.

 

Install Power Query and Power Query SDK

 

  • Ensure that Power Query is installed in your version of Excel. It typically comes built-in with Excel 2016 and later.

    •  

  • Install the Power Query SDK to enable advanced querying and data manipulation.

 

Create a Power Query Script to Call OpenAI

 

  • Open the Power Query Editor by selecting "Data" > "Get Data" > "Launch Power Query Editor".

    •  

  • Create a new blank query in which you will write the script to call the OpenAI API.

    •  

  • Enter the following Power Query M script to access OpenAI using your API key:

 

let
    apiKey = "YOUR_API_KEY",
    smallBusinessDescription = "YOUR_PROMPT_OR_INPUT",
    url = "https://api.openai.com/v1/engines/davinci-codex/completions",
    body = 
    "{" &
    """prompt"":""" & smallBusinessDescription & """," &
    """max_tokens"":100" &
    "}",
    source = Json.Document(Web.Contents(url,
        [
            Headers=[
                #"Content-Type"="application/json",
                #"Authorization"="Bearer "&apiKey
            ],
            Content=Text.ToBinary(body)
        ]))
in
    source

 

Retrieve and Use Data in Excel

 

  • After executing the query, retrieve the output from OpenAI in a structured format by transforming the JSON response into a table.

    •  

  • Load the data back into Excel for manipulation and analysis by clicking on "Close & Load" within the Power Query Editor.

 

Automate the Query with VBA (Optional)

 

  • For automation, use VBA to refresh the query or send different requests to OpenAI. Access the Developer tab and click on "Visual Basic".

    •  

  • Insert a new module and write a macro to automate the data retrieval process:

 

Sub RefreshOpenAIQuery()

    ThisWorkbook.Connections("Query - YourQueryName").Refresh

End Sub

 

Test and Iterate

 

  • Run your macro to ensure data is fetched from OpenAI and loads correctly into Excel.

    •  

  • Iteratively refine your query and VBA code to suit your specific use case.

How to Use OpenAI with Microsoft Excel: Usecases

 

Automated Financial Analysis using OpenAI and Microsoft Excel

 

  • Data Integration with Ease: Use Excel to import financial data from various sources, including live feeds or static datasets.

    •  

  • Natural Language Queries: Utilize OpenAI's natural language processing capabilities to perform sophisticated queries on financial data. Instead of traditional Excel formulas, input complex financial queries in plain English.

    •  

  • Trend Analysis and Forecasting: OpenAI models can analyze historical data trends and forecast future metrics directly within Excel, providing visualizations and insights to help in decision-making.

    •  

  • Automated Reporting: Create automated reports by combining Excel's data manipulation features with OpenAI's text generation capabilities. Craft detailed financial narratives based on data-driven insights.

    •  

  • Sentiment Analysis on Market News: Fetch financial news articles and run sentiment analysis using OpenAI, with results directly populating Excel charts to correlate market movements with public sentiment.

    •  

  • Error Detection and Suggestions: OpenAI can review Excel models, suggesting corrections for potential errors or optimizations for complex formulas and calculations.

 

import openai_excel_integration  

result = openai_excel_integration.analyze_financial_data(excel_file)

 

 

Enhanced Customer Feedback Analysis with OpenAI and Microsoft Excel

 

  • Data Aggregation: Gather customer feedback from various platforms and collate the data into an Excel spreadsheet for streamlined analysis.

    •  

  • Text Analysis with AI: Use OpenAI to perform sentiment analysis on customer feedback directly within Excel. This allows you to categorize feedback as positive, negative, or neutral without manually reading through each comment.

    •  

  • Actionable Insights: Generate actionable insights from customer comments using OpenAI to identify common themes or issues, which can be visualized in Excel for strategic decision-making.

    •  

  • Automated Feedback Summarization: Utilize OpenAI to create concise summaries of large volumes of feedback, presenting key takeaways in Excel dashboards for quick review by management.

    •  

  • Predictive Customer Satisfaction Trends: OpenAI's machine learning capabilities can be leveraged to predict future customer satisfaction trends based on historical feedback data visualized in Excel graphs.

    •  

  • Intelligent Prioritization of Customer Issues: With OpenAI, categorize and prioritize customer issues based on urgency and frequency, directly from within Excel, to optimize responses and enhance customer satisfaction.

 

import openai_excel_feedback  

summarized_feedback = openai_excel_feedback.analyze_feedback(excel_data)

Troubleshooting OpenAI and Microsoft Excel Integration

How to fix OpenAI API errors in Excel?

 

Understand the Error

 

  • Check the error message returned by the API. It often contains critical information about what went wrong. Common errors can be authentication issues, rate limits, or incorrect parameters.

    •  

  • Review OpenAI API documentation to ensure you're using the correct endpoint and parameters.

 

Troubleshoot Common Issues

 

  • Ensure your API key is correctly set in Excel. Verify that there are no extra spaces or unseen characters.

    •  

  • Check your network stability. A poor connection might cause intermittent errors.
  • Make sure to respect API rate limits. Implement mechanisms to manage requests effectively.

 

Implement Fixes

 

  • To handle missing headers or wrong methods, correct your Excel script:

 


With CreateObject("MSXML2.ServerXMLHTTP.6.0")
    
    .Open "POST", "https://api.openai.com/v1/endpoint", False
    .setRequestHeader "Content-Type", "application/json"
    .setRequestHeader "Authorization", "Bearer YOUR_API_KEY"
    .Send "{ ""your"": ""payload"" }"

End With

 

  • If rate limiting is an issue, consider adding delays between requests:

 


Application.Wait (Now + TimeValue("0:00:10"))

 

Can ChatGPT generate Excel formulas?

 

Can ChatGPT Generate Excel Formulas?

 

  • Overview: ChatGPT can help generate and explain Excel formulas based on user queries.

    •  

  • Use Cases:
    • Simple arithmetic operations: =SUM(A1:A10)
    • Conditional logic with =IF(A1>10, "Yes", "No")
    • Lookup functions: =VLOOKUP(B2, A1:D10, 3, FALSE)

    •  

  • Guidance: Describe the problem clearly, including cell references and desired outcomes.

    •  

  • Limitations: ChatGPT requires context; ambiguous requests may need clarification.

    •  

 

```excel

=AVERAGE(B1:B10)

```

 

How to connect OpenAI language models with Excel VBA?

 

Setup Environment

 

  • Register for an API key from OpenAI if you haven't already.

    •  

  • Ensure the VBA environment is prepared for HTTP requests. This might require a library like MSXML2.

 

Create API Request Function

 

  • Write a VBA function to make HTTP POST requests to OpenAI's API.

    •  

  • Use the MSXML2 library objects for XML HTTP requests.

 

Function CallOpenAIAPI(prompt As String) As String
    Dim http As Object
    Set http = CreateObject("MSXML2.XMLHTTP")
    Dim url As String
    Dim apiKey As String
    apiKey = "YOUR_OPENAI_API_KEY"
    url = "https://api.openai.com/v1/engines/davinci-codex/completions"

    Dim requestBody As String
    requestBody = "{""prompt"":""" & prompt & """, ""max_tokens"":150}"

    http.Open "POST", url, False
    http.setRequestHeader "Content-Type", "application/json"
    http.setRequestHeader "Authorization", "Bearer " & apiKey
    http.send requestBody

    CallOpenAIAPI = http.responseText
End Function

 

Integrate with Excel

 

  • Invoke the function within an Excel worksheet to display results.

    •  

  • Map the function to a button for UI integration.
