Introducing ChatGPT for Excel and new financial data integrations

OpenAI has launched ChatGPT for Excel in beta, an add-in that embeds ChatGPT directly into workbooks to assist with building, updating models, and running scenarios using plain language commands. This feature is powered by GPT-5.4, an advanced model optimized for financial reasoning, which showed significant performance improvement on internal benchmarks compared to GPT-5. The tool allows users to generate or update live Excel models while preserving structure, trace errors, and explain formula logic, with calculations running natively in Excel for auditability. Access is rolling out to various paid users in the U.S., Canada, and Australia, with Google Sheets integration coming soon.

Additionally, ChatGPT is enhancing its capabilities for finance professionals through new data integrations with providers like Moody’s, Dow Jones Factiva, and others, making it easier to work with trusted external data inside ChatGPT workflows. This, combined with GPT-5.4's improved context handling, helps teams accelerate research, model refreshes, and cited outputs for tasks like valuation and due diligence. For enterprise users, ChatGPT Enterprise offers robust security, governance features including RBAC, SSO, and data encryption, ensuring firm data is protected and not used for model training by default.
