Excel AI Assistant

Excel365 AI 万能助手

Excel365 AI 万能助手 is an AI productivity add-in for Microsoft Excel. It lets you describe a spreadsheet task in natural language and turns your request into a practical processing plan, formula recommendations, clear analysis steps, or executable code.

Key capabilities

• Natural-language spreadsheet work: Ask for data cleanup, formatting, categorization, summaries, calculations, or analysis without memorizing Excel formulas.
• Conversational task planning: The AI sidebar breaks a request into understandable steps and helps you review the intended result before execution.
• Flexible execution modes: Choose Speed Mode for high-volume routine work, Reasoning Mode for complex logic and anomaly analysis, or Comprehensive Mode for a balance of speed and reliability.
• Self-healing workflows: Detect and help correct common spreadsheet issues, such as formula errors after row changes, and support safe value completion and recalculation.
• Date-based local history: Organize conversation and operation records by date so you can copy, insert, resend, archive, or delete previous tasks when needed.
• Local data isolation: Keep frequent interactions and operation records in a locally isolated database for more controlled reuse and auditing.

Typical use cases

• Merge quarterly sales reports.
• Categorize a column and calculate month-over-month changes.
• Detect formula errors and clean financial or billing data.
• Fill missing cost values with an appropriate statistical value.
• Forecast sales trends and prepare analysis steps.
