In this case, when you save an Excel Workbook, a "privacy issue warning" dialog box appears, for example, "privacy issue warning" is displayed in Excel 2010: this document contains macro, ActiveX control, XML extension package information, or Web components, which may contain personal information and cannot be deleted through the 'document Inspector."
The reason for this problem is that the workbook contains macros, ActiveX controls, and other content, while Excel is set to automatically delete the personal information in the file attributes when saving the file, so this dialog box appears. To avoid this prompt, perform the following settings:
Excel 2003: click "Tools> Options> Security" in the menu, cancel "delete personal information from file attributes when saving" under "personal information options", and then confirm.
Excel 2007/2010: click "office" (or file menu) → Excel options (or options) → trust center ", click" trust center Settings ", and select" personal information options ", under "document-specific settings", deselect "delete personal information from file attributes when saving" and then confirm. This option is only valid for the current workbook. In addition, this option is unavailable when you create a workbook. This option is available only when the document is checked and personal information is deleted with the document checker.
