When exporting an Excel doc, for example to CSV, the app makes the new file (CSV) the active document. This has serious consequences if I continue to make changes in the new doc when I think I'm still in the native doc (xlsx). I find myself exporting to CSV, and then closing this CSV file, and finally reopening the original Excel doc.
