Microsoft Excel is no longer just a spreadsheet tool for data entry and basic calculations. With the integration of artificial intelligence (AI), Excel has evolved into a powerful platform for data analysis, automation, and intelligent decision-making. In this article, you’ll learn how to leverage AI in Excel through various methods—from Microsoft Copilot to OpenAI integrations—along with detailed steps and practical applications.
Microsoft 365 Copilot: AI Built into Excel
What Is Microsoft Copilot?
Microsoft Copilot is an AI assistant embedded directly into Microsoft 365 applications, including Excel. It uses large language models to understand natural language queries and perform complex operations without requiring manual formulas or scripting.
Requirements to Access Copilot

An updated version of Excel that supports Copilot
Internet access for cloud-based AI processing
How to Enable and Use Copilot in Excel
1. Open Excel with a Microsoft 365 account
2. Locate the Copilot icon at the top-right corner of the screen
3. Click on it to activate the AI assistant
4. Enter a natural language prompt such as:
“Summarize total revenue by month”
5. Copilot automatically generates formulas, tables, or charts based on the query
Key Features of Copilot
Data summarization
Automatic chart creation
Formula explanation and generation

Using External ChatGPT to Analyze Excel Data
This approach involves manually copying data from Excel and pasting it into an AI interface like ChatGPT to obtain external analysis.
How It Works
Step 1: Copy Excel Data
Select the relevant range and copy it (Ctrl+C)
Step 2: Paste into ChatGPT
Open ChatGPT and paste the data with a prompt like:
“Analyze this table and identify key insights.”
Step 3: Paste Results Back into Excel
Once ChatGPT provides the analysis, copy the response and paste it into a new worksheet or notes column in Excel.

Using VBA and OpenAI API for Custom AI Functions
Advanced users can connect Excel to the OpenAI API via VBA scripting. This allows direct AI interactions within Excel cells.
What Is the OpenAI API?
The OpenAI API enables access to powerful AI models like GPT-4 using HTTP requests. You can send data to the model and receive intelligent responses programmatically.
Setting Up the VBA Script
Prerequisites
OpenAI API key (accessible from OpenAI account)
Basic knowledge of VBA scripting in Excel
Example VBA Code
Sub GetAIResponse()
Dim http As Object
Set http = CreateObject(“MSXML2.XMLHTTP”)
Dim url As String
url = “https://api.openai.com/v1/completions”
Dim API_KEY As String
API_KEY = “YOUR_API_KEY_HERE”
Dim data As String
data = “{“”model””:””text-davinci-003″”,””prompt””:””Summarize this data.””,””max_tokens””:100}”
http.Open “POST”, url, False
http.setRequestHeader “Content-Type”, “application/json”
http.setRequestHeader “Authorization”, “Bearer ” & API_KEY
http.Send data
MsgBox http.responseText
End Sub
Use Cases of VBA + AI Integration
Classifying data based on custom criteria
Summarizing long text in cells
Auto-generating responses or reports
Enhancing spreadsheet automation
Conclusion: AI Transforms Excel into a Smart Analytics Tool ,
Artificial intelligence dramatically expands what Excel can do. Whether through Microsoft Copilot, ChatGPT add-ins, external integrations, or custom VBA coding, AI empowers users to work smarter, not harder. As AI continues to evolve, Excel will become an even more essential tool for intelligent data management.
