Anthropic Takes Aim at Microsoft’s Core Office Products

At an event in San Francisco on Tuesday, Anthropic unveiled Claude Sheets, an AI-powered spreadsheet tool that competes directly with Microsoft Excel. The launch is part of Anthropic’s effort to take Claude beyond chatbot conversations and into the workplace ecosystems of Microsoft and Alphabet Inc. (NASDAQ:GOOG).

Claude Sheets can generate and edit files, create multiple tabs, insert formulas and apply formatting. Coworkers with editing access can work on a spreadsheet alongside Claude, and the tool outlines the AI’s changes so users can track them. Files export to Excel’s XLSX format or CSV, and the tool works with partner products such as Airtable, Asana, Monday.com and Smartsheet. Sheets is currently in beta for paid subscribers.

Excel was only one target. Anthropic also introduced Claude Meetings, an AI assistant that joins Google Meet calls to take notes, capture decisions and identify action items. The feature is limited to Team and Enterprise customers for now. The company also introduced Claude Whiteboards, a collaborative brainstorming tool that turns team ideas into action items, which is in beta for all paid users.

Investors worry that if businesses start handling spreadsheets, meetings and collaboration directly inside Claude, Microsoft could lose ground in its lucrative Microsoft 365 franchise, where per-seat subscriptions and Copilot add-ons drive a large share of its recurring revenue.

Microsoft Also Faces Washington Fight Over Chinese Data Center Gear

Microsoft is also dealing with a policy issue. The company and technology industry groups are reportedly pressing the Trump administration to drop a proposed ban on certain Chinese data-center technology, Reuters reported Tuesday.

The groups met with White House science policy and National Security Council officials and warned that supply-chain disruptions could delay data-center construction and weaken the U.S. lead in AI. According to market intelligence firm Cleanview, Microsoft has 35 U.S. data centers under construction and another 134 in the pipeline.

The Federal Communications Commission proposal targets Chinese optical transceivers used in AI data centers, over concerns Beijing could use them to steal data or disrupt operations. BNP Paribas warned in August that such a ban could make U.S. infrastructure harder and costlier to build.
