Anthropic has unveiled Claude for Excel, an AI assistant that can read, edit, and generate spreadsheets from a sidebar while tracking its actions and citing source cells. The beta, limited to about 1,000 Max, Enterprise and Teams customers, connects to live financial data feeds from Moody’s, LSEG, Egnyte and Aiera, giving analysts real‑time pricing, earnings and credit information. Early deployments at AIG and Norway’s sovereign wealth fund claim five‑fold faster business‑review cycles and a 20% productivity boost, respectively, translating into hundreds of thousands of saved work hours.
