Microsoft adds accounting skills to Copilot in Excel
25+ finance skills and partner plugins: account reconciliations, draft journal entries (accruals, reclasses, allocations), variance reporting, plus audit, tax and compliance workpapers. Accounting capabilities are in Frontier (early access) for Copilot in Excel and Cowork; partner plugins include QuickBooks and Xero. Microsoft says prompts, responses and documents aren't used to train the foundation models.
