x.ai released a new Grok add-in for Microsoft Excel on July 20, 2026. This tool allows users to query spreadsheet data using plain English, generate formulas, and run scenarios directly within the interface. By selecting a data range, users can prompt the model to identify trends or outliers, with the system providing citations linked to specific cells and generating charts that appear directly within the sheet.

The add-in handles formula syntax based on user descriptions, allowing for complex tasks like averages, sorting, and filling data. It also supports predictive testing and forecasting without requiring manual sheet reconstruction. Furthermore, the tool integrates with connectors to pull context from SharePoint, Google Drive, or recent emails. Grok for Excel is available as a free Microsoft 365 add-in via the Microsoft Marketplace and supports Word and PowerPoint.
