- Evaluating different AI tools for generating formulas, analyzing data, and automating tasks in Excel.
- Observed behavior
- Seeking clarity on how integrations, AI features, and data-handling models differ between the two platforms.
Determine whether you need AI assistance directly integrated into your spreadsheet application or if a standalone web-based AI assistant is sufficient for your data tasks.
Review Microsoft's Official Comparison and Resources
Consult Microsoft's official documentation and community to understand the exact data-handling policies and integration features of Microsoft 365 Copilot compared to ChatGPT.
ChatGPT is a highly versatile, standalone AI model that requires you to manually copy and paste data or upload files for analysis. In contrast, Microsoft 365 Copilot is natively integrated into the Microsoft Office ecosystem, allowing it to directly read, analyze, and format your Excel spreadsheets.
Security and data handling are also major differences. Copilot inherits your organization's Microsoft 365 security and compliance policies, meaning it does not use your proprietary business data to train foundational models.
Visit the official Microsoft website and search for their detailed article comparing ChatGPT and Microsoft 365 Copilot to understand the architectural differences.
Check your Microsoft 365 Admin Center or Microsoft's Trust Center to see how Copilot processes your Excel data securely without training public models.
For specific questions on how to trigger Copilot within an Excel workbook (e.g., generating pivot tables or formula columns), visit the dedicated Microsoft 365 Copilot community forums.

Frequently Asked Questions
Can ChatGPT directly edit my Excel files like Microsoft Copilot?
No. ChatGPT operates in a web browser and cannot directly manipulate the cells in your local Excel application. You must either copy and paste data into ChatGPT or use the Advanced Data Analysis feature to upload a file, have ChatGPT process it, and then download the modified file. Microsoft Copilot works natively inside the Excel app.
Does Microsoft Copilot use my Excel data to train its AI models?
According to Microsoft, Microsoft 365 Copilot inherits your organization's existing security, privacy, and compliance policies. It processes your data within your organization's tenant and does not use your business data to train its foundational large language models.
Which AI is better for generating complex Excel macros (VBA)?
Both tools are proficient at writing code. ChatGPT is widely praised for generating complex VBA macros that you can easily copy and paste into the Excel VBA editor. Microsoft Copilot is also capable but currently leans heavily towards automating tasks using modern Office Scripts.
Is WPS Office compatible with standard Excel formulas generated by AI?
Yes. WPS Office is fully compatible with standard Microsoft Excel formats and formulas. If you use ChatGPT to generate a complex nested formula, you can confidently paste it into a WPS Spreadsheet and it will calculate correctly.
