OpenAI is launching ChatGPT for Excel in beta, an Excel add-in that embeds ChatGPT directly into workbooks to help build and update models, run scenarios, and generate outputs based on cells and formulas. Powered by GPT‑5.4, it assists users in doing more within Excel, enables power users to work faster, and can improve consistency across teams.
OpenAI is also adding financial data integrations directly into ChatGPT for providers including FactSet, Dow Jones Factiva, LSEG, Daloopa, S&P Global, and others, making it simpler to work with trusted financial data inside ChatGPT. Together, these capabilities help teams reduce manual work and spend more time on analysis, decisions, and execution.
An AI Model Optimized for Finance Workflows
GPT‑5.4 (as GPT‑5.4 Thinking) is available in ChatGPT, Codex, and the API. It is OpenAI's most advanced model, well-suited for financial reasoning and Excel-based modeling. OpenAI collaborated closely with industry practitioners to improve GPT‑5.4 on real-world finance workflows that typically take analysts hours or days, including financial modeling, scenario analysis, data extraction, and long-form research. The result is stronger performance on the tasks finance professionals depend on daily.
On OpenAI's internal investment banking benchmark-which evaluates real-world workflows such as building a three-statement model with proper formatting and citations-performance improved from 43.7% with GPT‑5 to 87.3% with GPT‑5.4 Thinking.
ChatGPT for Excel in Beta: Build, Update, and Analyze Spreadsheet Models Directly in a Workbook
ChatGPT for Excel is a version of ChatGPT embedded directly in spreadsheets that can build, analyze, and update models using the same formulas and structures teams already rely on. Analysts, strategists, researchers, and accountants can move faster, reduce manual work, and focus on judgment and decision-making rather than writing formulas, tracing links, and fixing models.
How It Works
- Build and update spreadsheet models faster. Instead of building spreadsheet models or running scenario analysis manually, teams can describe what they need in plain language, and ChatGPT will create or update live Excel models directly in the workbook. Teams can run data analysis, reporting, inventory management, and budgeting-all while preserving structure, formulas, and assumptions in a formatted, Excel-native workbook.
- Get insights from large spreadsheets without manual reconciliation. ChatGPT can reason across workbooks, understand how sheets and formulas connect across the model, explain why outputs changed, trace and fix errors, and show how assumptions flow through a model. This is especially useful when users inherit existing templates, need to get up to speed quickly, or want to understand and test a workbook before making decisions.
- Follow the logic and trust the outputs. ChatGPT explains what it is doing as it works and links answers to the exact cells it references and updates. Because calculations run directly in Excel, teams can trace assumptions, audit formulas, and verify how results were produced. Before making changes to a workbook, ChatGPT asks for permission, so users can review each step and undo edits if needed.
Known Limitations in Beta
OpenAI is improving ChatGPT for Excel quickly based on user feedback. Some responses may take longer as performance is optimized, and generated outputs may occasionally require cleanup or adjustment to match preferred spreadsheet formatting or layout conventions. ChatGPT can generate and explain formulas, but complex formulas or edge cases may still require manual refinement.
Getting Started
ChatGPT for Excel in beta is rolling out for ChatGPT Business, Enterprise, Edu, Teachers, Pro, and Plus users in the U.S., Canada, and Australia. ChatGPT for Google Sheets is coming soon.
In Enterprise, Edu, and Teacher workspaces, access is off by default. Admins can enable it for specific users with custom roles and group permissions.
Financial Data Integrations in ChatGPT
For teams working in financial workflows, new data integrations and support for proprietary data through building custom apps using Model Context Protocol (MCP) make it easier to bring market, company, and internal data into a single workflow in ChatGPT. With GPT‑5.4, ChatGPT can handle longer context and more complex tasks, helping teams move faster on company research, model refreshes, and cited outputs for valuation, diligence, underwriting, and related work.
Simplify research and analysis: Integrations released alongside this launch-including Moody's, Dow Jones Factiva, MSCI, Third Bridge, and MT Newswire, with FactSet coming soon-bring market, company, and internal data into a single workflow in ChatGPT as part of a growing ecosystem of apps. This helps users spend less time gathering inputs and produce cited outputs such as earnings summaries, valuation snapshots, and credit memos faster.
Quickly conduct due diligence: Teams can also use apps with research in ChatGPT to pull from filings, transcripts, decks, and spreadsheets to produce structured, cited outputs that export to PDF or Microsoft Word. Recent updates give users more control over the research process, including the ability to focus on specific websites and data sources, shape the research plan before and during a run, and review sources and citations in a redesigned workspace.
Security, Governance, and Control
For organizations adopting ChatGPT at work, ChatGPT Enterprise includes the security, governance, and access controls needed to use ChatGPT confidently, especially in regulated or data-sensitive environments:
- Manage and monitor access with RBAC, SAML SSO, SCIM, and audit logs, with support for common DLP and SIEM tools.
- Protect firm data with encryption in transit using TLS 1.2+ and at rest with AES-256, plus enterprise key management support.
- Meet regional data requirements with data residency and regional processing controls.
- By default, data shared with ChatGPT Enterprise is not used to train or improve OpenAI's models.
Customer Impact
OpenAI is working closely with financial institutions as they apply ChatGPT across research, underwriting, auditing, client engagement, code modernization, and operations. Across banks, asset managers, and insurance companies, impact is being seen in workflows like due diligence, client experience, and investment research.
Looking Ahead
This launch builds on OpenAI's ongoing work with analysts, strategists, researchers, and accountants. OpenAI is learning from real-world deployments to improve its products and models and help institutions move faster while operating responsibly in regulated environments. Enterprise customers can build directly with OpenAI or work alongside experienced partners such as Accenture, Bain, Boston Consulting Group (BCG), McKinsey & Company, and PwC to integrate AI into existing data, applications, and operating models.
