The message you are seeing in Excel is a warning that your document may contain macros, ActiveX controls, XML expansion pack information, or web components that could potentially contain personal information that cannot be removed by the Document Inspector.

To remove these elements from your Excel document, you can follow these steps:

1. Open the Excel document that you want to remove macros, ActiveX controls, XML expansion pack information, or web components from.
2. Click on the "File" tab in the top left corner of the screen.
3. Click on "Info" in the left-hand menu.
4. Click on "Check for Issues" in the middle of the screen.
5. Click on "Inspect Document" in the drop-down menu.
6. In the Document Inspector dialog box, check the boxes next to "Macros, ActiveX controls, XML expansion pack information, and/or Web components" depending on which elements you want to remove.
7. Click on "Inspect" to start the inspection process.
8. Once the inspection is complete, click on "Remove All" next to each element that was found.
9. Save the document.

This should remove any macros, ActiveX controls, XML expansion pack information, or web components that were present in your Excel document. If you are unsure about what these elements are or how they got into your document, it may be a good idea to consult with an IT professional or do some research to ensure that your document is secure.
