ChatGPT to write your Excel formulas

To use ChatGPT for writing an Excel formula, you’ll need access to either Microsoft Excel or Google Sheets. These formulas can be used in both applications. To access ChatGPT, you’ll need an OpenAI account. Keep in mind that AI chatbots, while knowledgeable, may need help understanding nuances as well as humans do. They can make mistakes or need clarification on prompts.

1. Open ChatGPT and your spreadsheet


To access ChatGPT, open your Excel file or Sheets spreadsheet and visit If you’re not logged in with your OpenAI account. If you don’t have an account, you can create one here. Once you log in, you will be directed to a chat conversation with ChatGPT.

Here is an example spreadsheet for January 2023, showing a made-up inventory of devices. There are 45 products in column A. Each product has an SKU number in column B, inventory amount in column C, quantity purchased in January in column D, price per unit in column E, and the subtotal in column F (formula already applied).

We’ll use ChatGPT to make some examples of formulas. These include calculating sales tax (column G), seller’s commission (column H), total (column I), and leftover inventory for the next month (column J).

FAQs – ChatGPT to Write Excel Formulas

Is there a way to use AI for formulas within Excel?

It would be great if Microsoft Excel had an AI tool built-in, making it as easy to generate formulas as using ChatGPT. Currently, Microsoft is introducing AI tools called Copilot for its products, including the Microsoft 365 suite. Microsoft Copilot is not widely available yet, but it would be great to include a GPT-4-integrated Microsoft Excel.

Why is the formula from ChatGPT not working?

If ChatGPT gives you a formula that doesn’t work in Excel or Sheets, it may have needed to understand your prompt. Check the formula for errors on ChatGPT’s and modify your prompt to get the correct answer. For the total cost, create a formula that adds the values in columns F, G, & H.

I didn’t mention that I only wanted to add the values in cells F3, G3, & H3. As a result, the formula added the values in the entire column range, which is different from what we wanted. I fixed my request to ChatGPT. Now, I’m asking it to make a formula that adds the values in cells F3, G3, & H3 to calculate the total cost.

Can ChatGPT write intricate Excel formulas?

ChatGPT is an excellent tool for creating formulas in Excel or Google Sheets, whether simple or complex. For this example, we used simple formulas to guide you through the process. However, you can ask the AI chatbot to create more complex formulas and see how far they can go. To get accurate results from ChatGPT, make sure your prompts are clear.

Can you use Bing Chat to write Excel formulas?

Bing Chat and Google Bard, along with other AI chatbots, can also help you create Excel formulas using the same steps mentioned above.
