💼 Grok Now Works in Microsoft Excel

xAI has released an official Grok add-in for Microsoft Excel, available via the Microsoft Marketplace. The plugin operates as a sidebar and allows for real-time searching, automatic data updates in spreadsheets, and building financial models based on text queries.

🌍 xAI is shifting from model development to fighting for the productivity market, directly challenging Microsoft Copilot and Google Gemini within office application ecosystems.

👤 Users can now leverage Grok's capabilities directly inside Excel spreadsheets to automate routine calculations; however, users should remain cautious due to the risks of AI hallucinations and data security concerns.
