OpenAI has launched ChatGPT for Excel in beta, an add-in powered by GPT-5.4 Thinking that builds, updates, and analyses financial models directly inside workbooks. The tool is available now to ChatGPT Pro, Enterprise, Business, and Edu subscribers.
The add-in integrates GPT-5.4 Thinking directly into the Excel environment. Users can prompt the model to create or modify financial models, run analysis, and work with data without leaving the spreadsheet. Financial data integrations are included in the beta, meaning the tool can reference live financial data as part of its workflow rather than relying solely on what is already in the file.
Excel is the backbone of financial reporting, budgeting, and data analysis for most Australian businesses, from small operators managing their own books to finance teams inside large organisations. The practical problem with most AI tools has been the overhead of moving data out of spreadsheets, working with it elsewhere, and reformatting results back into a usable structure. ChatGPT for Excel removes that step by working directly inside the tool teams already use.
For business owners whose teams spend significant time building or updating financial models, the relevant question is not whether this technology exists but whether it works reliably for the specific tasks your people do. Beta periods are the right time to run structured tests, document where the tool saves meaningful time, and identify where human review remains essential. The businesses that build that evaluation capability now will be in a much better position when the tool reaches general availability and competitors start using it at scale.
AI is not moving into business tools at some point in the future. It is in Excel now. The practical question for most business owners is whether their teams are aware of it and whether they have a way to test it properly.
