Today AI Intelligence Brief
Microsoft has launched the Change History feature for Excel, which, combined with Copilot's
reasoning capabilities, generates modification descriptions. Users can understand important changes in a workbook during a specific period using natural language. The feature marks manual edits and Copilot-assisted modifications with different colors, supports undoing a collaborator's AI-assisted changes while retaining their manual edits, and can analyze recent modifications that may have caused formula failures when a formula is abnormal. The original text did not disclose parameters such as the maximum trace-back period, the scale that can be handled, and response time.
该功能读取 Excel 已有编辑记录，可汇总具体修改内容、影响及相关编辑者。微软还展示了针对协作者 AI 辅助改动的撤销操作，并支持在公式异常时分析近期哪些修改可能导致公式失效。最长追溯周期、工作簿规模和响应时间尚未披露。
Aioga 观点
Aioga 判断：Change History 将修改记录、自然语言查询和公式排错联系起来，重点价值在于降低多人协作工作簿的追溯成本。但其实际适用范围仍取决于历史记录覆盖、处理规模和分析准确性，现有材料不足以确认使用效果。
影响与后续
可能影响：团队需要关注人工编辑与 Copilot 辅助修改的区分方式，以及撤销 AI 辅助改动时保留手动编辑的边界。该功能可能减少逐项比对记录的工作，但不代表能够准确判定所有公式异常原因，使用时仍应复核修改内容。 后续观察：应关注微软后续是否公布最长历史追溯周期、可处理的工作簿规模、响应时间及具体开放范围；同时需要观察实际场景中自然语言修改说明、影响分析和公式排错结果的准确性。
