OpenAI has introduced ChatGPT for Excel in beta, an add-in that embeds ChatGPT directly into spreadsheets to help users build, update, and analyze models using natural language. Powered by the GPT‑5.4 model, the tool enables teams to automate financial modeling, scenario analysis, and data reconciliation within Excel workbooks. The beta version is available to ChatGPT Business, Enterprise, Edu, Teachers, Pro, and Plus users in the U.S., Canada, and Australia, with Google Sheets support coming soon.

Alongside the Excel integration, OpenAI announced new financial data connections for ChatGPT, including integrations with FactSet, Dow Jones Factiva, LSEG, Daloopa, S&P Global, Moody’s, MSCI, Third Bridge, and MT Newswire. These additions allow users to access trusted market and company data directly within ChatGPT, streamlining research, valuation, and due diligence workflows. GPT‑5.4, optimized for finance, shows improved performance on internal benchmarks for financial reasoning and modeling tasks.

OpenAI emphasized enterprise-grade security and governance features in ChatGPT Enterprise, including encryption, role-based access control, and compliance tools. The company is collaborating with financial institutions to apply these capabilities across research, underwriting, auditing, and client engagement.
