ChatGPT for Excel in Beta

OpenAI is rolling out ChatGPT for Excel in beta, an Excel add-in that brings ChatGPT directly into spreadsheets. The tool lets users build, update, and analyze models using plain language instead of manually writing formulas. Available for ChatGPT Business, Enterprise, Edu, Teachers, Pro, and Plus users in the U.S., Canada, and Australia, it helps analysts, strategists, researchers, and accountants move faster while reducing manual work.

Key Capabilities

  • Build and update models in plain language: Describe what you need, and ChatGPT creates or updates live Excel models directly in the workbook, preserving structure, formulas, and assumptions.
  • Analyze large spreadsheets: ChatGPT can reason across multiple workbooks, understand how sheets and formulas connect, trace errors, and explain how assumptions flow through a model.
  • Explainable and auditable: All calculations run directly in Excel. ChatGPT links answers to exact cell references, explains its work, and asks for permission before making changes—enabling full audit trails.

GPT-5.4: Finance-Optimized Model

GPT-5.4 (including GPT-5.4 Thinking) powers the new Excel feature and is available today in ChatGPT, Codex, and the API. On OpenAI's internal investment banking benchmark, GPT-5.4 Thinking achieved 87.3% accuracy, up from 43.7% with GPT-5, demonstrating significant improvement on real-world financial modeling, scenario analysis, and research workflows.

Financial Data Integrations

ChatGPT now integrates directly with major financial data providers—including FactSet, Dow Jones Factiva, LSEG, Moody's, MSCI, and others—allowing users to pull market, company, and internal data into a single workflow. Teams can produce cited outputs like earnings summaries, valuation snapshots, and investment dossiers faster. Users also have new controls over research, including the ability to focus on specific data sources and review citations in a redesigned workspace.

Known Limitations and Availability

In beta, some responses may take longer to process, and generated outputs may require minor formatting adjustments. Complex formulas and edge cases may still need manual refinement. ChatGPT for Google Sheets is coming soon. For Enterprise, Edu, and Teacher workspaces, access is off by default and must be enabled by admins with custom role controls.
