The software and browser automation space is quickly becoming one of the biggest battlegrounds in AI. Every major player wants to be the tool people rely on inside the apps they already use every day. Claude made an early move with its Excel plugin, giving users a way to build spreadsheets, pull insights across tabs, work with formulas, and update workbooks much faster without doing everything manually. That kind of workflow is naturally appealing because Excel is still at the center of how many teams operate. So it made perfect sense for ChatGPT to enter the same space as ChatGPT for Excel.
And that matters because Excel is everywhere. It is one of the most widely used business tools in the world, and millions of people depend on it every day for forecasting, budgeting, financial modelling, reporting, sales tracking, operations planning, and performance analysis. The problem is that a lot of this work is repetitive, manual, and slow. That is exactly why AI inside Excel is so compelling. Instead of spending hours writing formulas, cleaning messy data, updating assumptions, or rebuilding reports, users can simply describe what they want in plain language and let the AI handle a big part of the heavy lifting.
In this tutorial, we’ll show you how to install ChatGPT for Excel, review existing spreadsheet models, use plain-language prompts to update formulas, edit assumptions and input values, add new calculated columns, and check the accuracy of the AI-generated changes.
By the end of this tutorial, you’ll be able to:
Install the ChatGPT for Excel plugin
Review the existing spreadsheet model
Edit assumptions and input values
Add new calculated columns
Reorganize and clean the model
Check the accuracy of the AI-generated changes
Let’s dive right into it!
