“Claude can work directly in Microsoft Excel, PowerPoint, Word, and Outlook via add-ins. In Outlook, it can act as a chief of staff that triages your inbox, arranges meetings, and drafts responses in your voice. In Excel, it builds financial models from filings and data feeds, audits formulas across linked workbooks, and runs sensitivity analyses. In PowerPoint, it drafts decks that update automatically when the underlying numbers change. In Word, it edits credit memos against a firm’s own templates. Claude carries its knowledge and context across all four platforms: an analyst who’s started a model in Excel doesn’t need to re-explain it when that work moves to PowerPoint.”
