ChatGPT for Excel review

ChatGPT for Excel is an add-in that opens ChatGPT in a sidebar next to your workbook, and OpenAI's help center says it can build, update and explain large multi-tab files with formulas, references and assumptions. You install it from the Microsoft Marketplace in Excel desktop or web and sign in with your ChatGPT account. It is available to Free, Go, Plus and Pro users as well as business plans, which makes it the easiest way to try an Excel AI add-in at no cost, though Free and Go get limited usage and Plus and Pro draw from an agentic usage limit. You can @ mention sheets, ask for a plan before big edits, and use Skills and apps. A version for Google Sheets works the same way. OpenAI lists limits: spreadsheet chats do not sync with your main history or memory, and VBA and macros may not be fully supported. We compared documented features and published prices.
