Reply To: Unlink .xlsx files from text?

Thank you for posting a smaller file! :-)

This file is linked on Master Page B. I see that in the right column of the Links panel. If you open Master Page B in the Pages panel and delete everything, the link goes away.

If you want it in the document, but not linked, you’ll have to update or locate the link (it’s missing for me), and then select it in the Links panel and choose Unlink from the panel menu.

(Linking to spreadsheets is inside Preferences > File Handling)
