Typical usage

Combined with official documents, Microsoft 365 Copilot has several types of high-frequency usage in AI office and efficiency scenarios:

• Word Copilot: Generate a draft article based on a brief description (such as "Write a 5-page report on market trends in 2025"); summarize existing documents, rewrite the tone, expand content, or compress and streamline existing documents; refine lengthy reports into key points and quickly understand long documents.
• Excel Copilot: Use natural language to query data (such as "Find products whose sales dropped by more than 10% in the last quarter"); automatically generate data analysis insights and visual charts; create complex formulas and pivot tables to explain the logic of existing formulas; identify trends and anomalies in the data.
• PowerPoint Copilot: Automatically generate a complete presentation based on a document or outline, including content, layout, and images; convert Word documents to PPT with one click; rewrite slide content to suit different audiences; add speaker notes to the presentation.
• Outlook Copilot: AI drafts replies to emails, generating contextually appropriate responses based on email content and conversation history; summarizes long email threads into key points with one click; intelligently sorts and prioritizes inboxes; and plans when emails are sent.
