Anthropic rolled out Claude Sheets, Claude Whiteboards and Claude Data to all paid plans on Tuesday, pushing the company straight into the office software market that Microsoft and Google have owned for decades. The announcement from the official Claude account drew more than 53,000 likes, making it the most engaged AI product post of the day, with users reading it as a direct shot at Microsoft's productivity suite.
Wall Street reacted immediately. Microsoft shares fell nearly 3 percent after the launch, a paper loss of more than $115 billion, while the wider Nasdaq 100 slipped only about 0.5 percent over the same stretch. Microsoft has since won back roughly half of that drop. Claude Sheets builds spreadsheets with tabs, formulas, formatting and dropdowns from a single prompt, and files export to .xlsx or CSV when users need the full power of Excel.
Claude Whiteboards turns a spoken plan into a shared board with timelines, owners and dates, so a team can brainstorm with Claude instead of pasting answers into another app. Both Whiteboards and Sheets are in beta, while Claude Data, formerly Dashboards, is now generally available and connects to warehouses and CRMs including BigQuery and Salesforce. Enterprise admins keep Sheets and Whiteboards off by default until they enable them, and Claude Data switches on automatically on November 19. The launch landed the same day Anthropic opened the roadshow for its proposed IPO.
