Excel's New Copilot Function: An AI-Powered Assistant in Your Spreadsheet

Updated on Nov 19,2025

Table of Contents

Microsoft Excel continues to evolve, incorporating artificial intelligence to enhance user experience and productivity. A recent addition is the Copilot function, designed to provide AI-driven answers directly within your spreadsheets. While currently available only to users on the Beta Insiders Channel with a paid Copilot license, it’s essential to understand its potential and limitations. This article explores the Excel Copilot function, its functionality, and whether it's a worthwhile investment.

Key Points

Excel's Copilot function uses AI to answer questions or instructions typed directly into cells.

Currently, it is exclusive to Microsoft 365 Beta Insiders with a $20/month Copilot license.

The function generates dynamic arrays or spill arrays based on AI analysis.

Copilot is designed to simplify complex tasks, but has limitations.

It is essential to remain aware of Microsoft's updates to Excel, even if they're not immediately relevant.

Users provide feedback with thumbs up or thumbs down to tweak and improve the tool.

Copilot may return results which are not reliable, and therefore should not be used in any high-stakes applications.

Understanding the Excel Copilot Function

What is Excel Copilot?

The Excel Copilot function is a new feature added by Microsoft that allows users to type a question or instruction directly into a cell. The function then uses artificial intelligence (AI) to analyze the input and provide an answer. This aims to streamline processes and make data analysis more accessible, particularly for complex tasks. It uses AI to provide answers and is intended to function as an assistant within Excel, offering solutions and insights based on user queries.

To use the Copilot function, you simply type your question or request into a cell, following the format =COPILOT(“[Your question or instruction]”). Excel then processes your input and generates a dynamic array or a spill array, which presents the answer directly within the spreadsheet.

However, there are limitations. As of now, the Copilot function is only available to users who are part of the Microsoft 365 Beta Insiders Channel and have a paid Copilot license, costing $20 per month. Also, to ensure the tool works, the Prompt should specify the column and row for the function.

The functionality has limited usage. It is more important than ever to make sure to stay aware of what Microsoft is adding to Excel, even if the features are not directly relevant.

How to Use the Copilot Function in Excel: A Step-by-Step Guide

Let’s walk through a practical example to illustrate how the Copilot function operates within Excel:

Scenario: You need a list of Mac operating systems since 2007.

Step 1: In cell A1, type the formula =COPILOT(“[Your question or instruction]”)

Step 2: Enter the prompt. Double click the field for the text and then type, “I need a list of the names of the Mac Operating Systems since 2007”.

Press enter.

Step 3: Review the results. A list of names are dynamically generated down column A. Each cell indicates “AI-generated”.

When you select a cell that the Copilot function generated, a pop-up that the value in that cell has been generated by AI shows in the lower-right corner.

You can provide feedback to Microsoft, tweaking and improving the tool for other users.

It's worth noting that when this demo was tested, the function only produced a list of names. Because of this, a second demo was required:

Step 1: Change the formula. To improve the output, edit the formula and add, “include the year of release”, to produce =COPILOT(“I need a list of the names of the Mac Operating Systems since 2007 include the year of release”).

As a result, the function alters what was in column A. This illustrates the ever-changing and slightly unstable nature of AI and the Copilot function.

However, to keep the original result, it is recommended to copy and paste values, rather than formulas. As functions recalculate when edited, use copy and paste > values to replace the formulas with static values.

Practical Use Cases and Examples of Excel Copilot

Analyzing and Summarizing Sales Data

Imagine you have a large dataset of sales records and need to quickly derive key insights. The Copilot function can help identify trends, patterns, and anomalies.

It is important to note that while the average result might be correct, it is more important than ever to acknowledge the limitations.

You can use a prompt like this:

=COPILOT(“I need 5 key insights from this data to give to the CEO”,’Sales Data’!A1:H51)

This will look at the range in the 'Sales Data' sheet, and put those insights in separate cells. To then present them to the CEO, you can combine the text with a few line breaks:

=TEXTJOIN(CHAR(10)&CHAR(10),TRUE,COPILOT(“I need 5 key insights from this data to give to the CEO”,’Sales Data’!A1:H51)) 

It is important to note that because you used AI, there is no guarantee that it will give appropriate feedback. Make sure to use the thumbs up or thumbs down to give feedback to Microsoft.

Extracting Information from Unstructured Data

Consider having a list of client contact details where the information is inconsistent, but you are looking to get contact emails. [t: 577]Instead of getting information through VLOOKUP, consider using this function:

=COPILOT(“Extract the email address”,A1:A20)

Copilot will then analyze the email address, extract it and display it.

Determining Sentiment in Performance Reviews

Copilot can help with providing employee performance reports by analyzing employee sentiments:

=COPILOT(“Is the review Positive, Negative or Neutral”,B2:B11)

Copilot will then analyze their strengths and weaknesses, and put positive or negative or neutral depending on the response.

Using the Correct Contexts

It is important to learn what context is needed. The second argument should be a range of cells. You should also specify whether you would like a positive, negative, or neutral sentiment.

Feedback

Clicking on the thumbs up or thumbs down sends feedback to Microsoft, which can be used to tweak and improve the tool.
