ChatGPT Revolutionizes Excel with Financial Data Integrations
OpenAI announced ChatGPT for Excel, a beta add‑in that embeds ChatGPT directly in Excel workbooks to build, update, and audit spreadsheet models using live formulas and workbook structure. The feature is powered by GPT‑5.4 (branded GPT‑5.4 Thinking), which OpenAI says is available in ChatGPT, Codex, and the API and has improved performance on finance workflows. OpenAI also added financial data integrations and partner apps (examples: FactSet, Dow Jones Factiva, LSEG, Daloopa, S&P Global, Moody’s, MSCI, Third Bridge, MT Newswires) and support for proprietary data via the Model Context Protocol (MCP). ChatGPT for Excel beta is available to Business, Enterprise, Edu, Teachers, K‑12, and to Pro/Plus users outside the EU; Enterprise workspaces include admin controls and security features (RBAC, SAML SSO, SCIM, audit logs, TLS/AES‑256, enterprise key management). OpenAI cites internal benchmark gains for GPT‑5.4 on investment‑banking tasks.
