100-word summary
OpenAI launched an Excel add-in that builds, updates, and analyzes financial models from conversational prompts. Type "add revenue scenarios" and GPT-5.4 edits your workbook directly, asking permission before changing cells and tracing every input to its result. It doubled accuracy on OpenAI's investment-banking benchmark, jumping from 44% to 87%. The beta includes live feeds from Moody's, MSCI, and Dow Jones, with FactSet coming soon. Available now to U.S., Canadian, and Australian business and premium subscribers. The question isn't whether AI will touch your spreadsheets anymore, it's whether anyone will still remember VLOOKUP syntax by 2027.
