OpenAI is bringing its flagship AI directly into Microsoft Excel with the beta launch of ChatGPT for Excel. This new add-in allows users to build, update, and analyze spreadsheet models using natural language prompts, aiming to accelerate workflows for analysts, strategists, and accountants.
The integration is powered by OpenAI's latest model, GPT-5.4, which has been fine-tuned for financial reasoning and complex spreadsheet tasks. This marks a significant step in embedding AI into core business tools, moving beyond standalone chatbots.
