ChatGPT for Excel Launches with New Financial Data Integrations

OpenAI has unveiled a beta version of ChatGPT for Excel built on GPT-5.4. This Excel add-in supports building, updating, and analyzing models directly within workbooks, boosting the efficiency of analysts, accountants, and others.

It also supports direct integration with major financial data providers such as FactSet, Dow Jones Factiva, LSEG, Daloopa, and S&P Global. This allows users to focus more on analysis and decision-making by leveraging trusted financial data within ChatGPT.

The key features of ChatGPT for Excel are as follows:

• Model Building and Updating: Creates live Excel models or performs scenario analysis using natural language commands, while preserving existing formulas and structure.
• Deriving Data Insights: Understands the connection structure between sheets and formulas to trace and fix errors, and explains why result values have changed.
• Transparent Logic Verification: Explains the calculation process and specifies referenced cells, with all changes executed only after user approval.

The new GPT-5.4 Thinking model scored 87.3% on OpenAI's internal investment banking benchmark. This shows a significant improvement in financial reasoning and modeling capability compared to the existing GPT-5's 43.7%.
