- SpaceXAI has just launched a Grok add-in for Excel
- However, OpenAI, Anthropic and others have already moved ahead of Grok.
- The latest Grok 4.5 model is considered an Excel genius
SpaceXAI (formerly xAI) launched Grok for Excel as an add-on that seeks to integrate Grok’s conversational AI capabilities into a side panel to make formulas, charts, analytics, and more easier.
Although the add-on is technically free, it requires a paid account to use the features, with only the SuperGrok, SuperGrok Heavy, and Business/Enterprise plans able to handle the tasks in the add-in.
SpaceXAI also refers to the add-in as a “free” Microsoft Marketplace tool, vaguely implying that it is free to use despite current account limitations.
Grok now also has an Excel add-in
“Describe the result and Grok handles the syntax: averages, sorts, and fills tasks like normal edits in the formula bar,” the company wrote in a post announcing the new tool.
Grok for Excel supports Excel 2019 or later on Mac as well as M365 and Web versions, and joins similar Word, PowerPoint, and Outlook add-ins. All Office add-ins promise to interact with documents, understand data, and write new content, but there are no standalone agent features like sending an email in Outlook.
In fact, SpaceXAI is just the latest company to recognize that individual sectors need role-specific support, with funding emerging as one of the priorities. OpenAI already has ChatGPT for Excel, Anthropic has Claude for Excel and of course Microsoft has its own Copilot add-on for paid plans.
The news comes days after the company launched its latest Grok 4.5 model. “Grok Build is capable of creating complex Excel models that involve web searches, using formulas across multiple sheets, and even leaving stickers or notes for future reference,” the company wrote.
SpaceXAI also praised the model’s capabilities in Word and PowerPoint.
