Bengaluru, March 6: OpenAI has introduced ChatGPT 5.4, its latest AI model upgrade designed to enhance professional productivity with advanced reasoning and deeper spreadsheet integration. The update brings a new “Thinking Mode” that improves problem-solving capabilities and provides users with a clearer view of how the AI reaches its conclusions. Alongside this, OpenAI has rolled out a native integration with Microsoft Excel and Google Sheets, allowing users to build and manage spreadsheets using simple natural language commands. The release is aimed particularly at finance professionals, analysts and data teams who rely heavily on complex spreadsheet workflows.

New ‘Thinking Mode’ for Better Reasoning

One of the most notable additions in ChatGPT 5.4 is the Thinking Model, which improves logical reasoning and complex analysis. Unlike earlier versions, the model presents an outline of its reasoning before generating results, giving users the ability to follow the AI’s logic and adjust instructions if necessary. ChatGPT Uninstallation Surge to 295% in US Amid OpenAI’s Controversial Defence Deal With Pentagon; Users Migrate to Anthropic Claude.

According to OpenAI’s internal benchmarks, the model shows a major improvement in financial reasoning tasks, with accuracy rising from 43.7 percent in earlier versions to 87.3 percent. This improvement can help professionals handle demanding tasks such as investment research, credit analysis and underwriting documentation. OpenAI Launches 'Your Year with ChatGPT' Feature, Allows Users to Get Personalised Recap of 2025 AI Interactions, Messages, Images, and More.

Native Excel and Google Sheets Integration

Another major highlight of the release is direct integration with Microsoft Excel through a new beta add-in. Instead of manually writing complicated formulas, users can simply describe a financial scenario in natural language, and the AI will generate a fully formatted spreadsheet.

Key capabilities include:

  • Formula Explanation: The AI can analyze existing spreadsheets and explain how formulas work or identify possible errors.

  • Verification Controls: Users must approve any changes, and the AI provides references to the exact cells used in calculations.

  • Google Sheets Compatibility: Similar functionality is being introduced for Google Sheets to support collaborative spreadsheet workflows.

Partnerships with Major Financial Data Providers

To improve reliability and real-world usefulness, OpenAI has partnered with several major financial data providers including S&P Global, Moody’s, LSEG and Dow Jones Factiva. Through these integrations, ChatGPT 5.4 can access market data, financial filings and corporate transcripts directly within spreadsheet workflows.

This allows analysts to automate valuation models, research reports and due diligence processes while working with trusted real-time data sources.

Availability and Enterprise Security

The new ChatGPT 5.4 features are currently rolling out in beta for users on ChatGPT Plus, Team, Enterprise and Edu plans. Initial access is available in the United States, Canada and Australia, with broader availability expected later.

OpenAI also emphasized enterprise security, confirming that data shared within the Enterprise version will not be used to train AI models. Despite improved reliability, the company still recommends human oversight when verifying complex financial models and specialized spreadsheet formatting.
