ChatGPT GPT 5.4: The new ChatGPT is no longer just a chatbot but an ‘AI co-pilot’ that has the ability to solve your complex business tasks in a jiffy. This update is going to pose a big challenge for rivals like Google and Anthropic.

The new ChatGPT can now understand the relationships between multiple workbooks.
New Delhi. OpenAI has launched its new model GPT-5.4. Through this new version, ChatGPT will now work directly within your spreadsheets and office tools, making data management much easier. The biggest feature of this update of ChatGPT is its direct partnership with Excel and Google Sheets. You no longer need to spend hours manually applying formulas for complex data analysis or budgeting. You can create live Excel models from ChatGPT by giving instructions in simple language. Be it inventory management or budgeting, this AI can go directly inside the workbook, write formulas and update the data. The most important thing is that it works without damaging the basic structure of Excel.
According to OpenAI’s benchmark test (GDPval), this AI outperformed human workers in 83% of real-world tasks across 44 different professions. This model can now create complex files and documents with less ‘back-and-forth’ (repeated questions and answers). It solves difficult problems faster by using fewer tokens, which not only saves time but also reduces costs.
The power to understand complex spreadsheets
Often understanding old and complex Excel files or templates is no less than a headache. The new ChatGPT can now understand the relationships between multiple workbooks. It’s easy to see how different sheets and formulas are related. If there is a change in the output of a report or there is an error in the data, it can immediately trace and fix it. This will prove to be a boon for those who want to extract important insights from large files.
reliable calculations
The biggest concern with AI is how it derived its results. OpenAI has found a solution to this through ‘logic tracking’. When ChatGPT performs a calculation in Excel, it will clearly indicate which cells it refers to. Users can audit every formula and verify assumptions. For security reasons, the AI will ask for your permission before making changes to any workbook.
