How do you quickly determine whether spreadsheet data displayed in a Word document is linked to source file?

To quickly determine if spreadsheet data in a Word document is linked to a source file, right-click on the data and choose "Linked Worksheet Object" or "Linked Excel Chart" if available. If the option to "Edit Links" appears, it indicates that the data is linked to an external file. Additionally, you may see the "Update Link" prompt when opening the document, which further confirms the data’s linked status.
