导出 SharePoint 列表的版本历史事件日志

Question

我正在寻找一个事件日志或完整版本历史记录，其中包含对 SharePoint 列表项目所做的所有更改。

版本历史已启用。当我右键单击一个项目并选择版本历史记录时，它实际上向我显示了我需要的所有数据：

• 修改的时间戳
• (Column, value) 新修改的列和它的新值对
• 修改人

现在我“只”需要在表格或文件（xlsx、xml、json、csv）中构建这些数据。并且对于 List 的所有项目。

我可以看到数据在那里。但是我还没有找到导出它的方法。到目前为止，我已经尝试使用 PowerShell 和 Power Automate 自定义 .iqy 文件，但没有成功。

我希望有一些方法可以让我获得完整的历史记录。我需要它来计算平均运行时间。

对于 SharePoint Online：
