To connect Claude AI to Excel, you need to follow one of the methods mentioned below.

Finally, you will be able to access Claude on Excel.
2] For Admins
If you have access to the Microsoft 365 Admin Center, and want to deploy the add-in to multiple users in an organization, go through the steps mentioned below.
- Go to the Microsoft 365 Admin Center.
- Navigate to Settings > Org Settings > User owner apps and services.
- Ensure the toggle for Let users access the Office Store is turned on. (Note: If this is disabled, admin-deployed add-ins may not appear. In that case, use the manifest file method below.)

Finally, try out Claude in Excel.
How to automate Data Analysis
Once connected, you can use the following features to automate your analysis workflow.
- Use cell-level citations: Ask questions about your data. Claude will highlight the relevant cells and provide clickable links to navigate to them directly. You do not need to search manually.
- Track changes: Ask Claude to update numbers or fix errors. It will highlight every cell it modifies and add explanatory comments. Review changes before accepting them.
- Update inputs safely: Change an assumption or input value. Claude will automatically maintain all formula dependencies and relationships. You do not need to trace dependent cells manually.
- Work across tabs: Ask questions that reference multiple sheets. Claude can read and analyze data across the entire workbook without you switching tabs.
- Apply formatting directly: Ask Claude to sort data, filter tables, modify pivot tables, or apply conditional formatting. The add-in uses Excel’s native controls to make these changes.
