OpenAI is launching "ChatGPT for Excel," a beta add-in that lets users create, edit, and analyze spreadsheets through natural language. The tool runs on the new GPT-5.4 model, which OpenAI says is specifically optimized for financial tasks like modeling, scenario analysis, and data evaluation.

OpenAI tested its own models alongside Opus 4.6 on an internal benchmark designed to evaluate real investment banking tasks, such as building a three-statement model with correct formatting and sources.
