SpaceXAI (SPCX.US) launches Excel version Grok plugin to fully embed in Office suite.

Elon Musk's SpaceXAI (SPCX.US) announced on Monday that it will be introducing its generative artificial intelligence (AI) chatbot Siasun Robot & Automation Grok into Microsoft Corporation (MSFT.US) Excel spreadsheet software. Users can now obtain this Microsoft 365 plugin for free through the Microsoft Marketplace. The plugin also supports Word and PowerPoint, marking Grok's full integration into the Microsoft Corporation Office suite. According to SpaceXAI, users can simply describe the desired outcome in everyday language, and Grok will automatically process the corresponding grammar and logic including calculating averages, sorting data, and auto-filling operations. These results will be displayed directly in the formula bar as with regular editing. Additionally, users can select a specific cell range and ask Grok questions, where Grok will reference specific data cells for answers and generate charts. The plugin also supports scenario testing and rerunning predictions, allowing users to test downside risk scenarios, rerun predictions, or complete tasks at the end of the month without manually rebuilding tables. The plugin can connect to external data sources, allowing users to request Grok to extract context information from recent emails or files in SharePoint, Google Drive.

On June 22nd, Grok was officially integrated into the Microsoft Corporation Office suite, allowing users to directly generate documents, presentations, and handle spreadsheet data based on text commands using the dedicated AI agent in the app sidebar.
