Microsoft 365 Autosave with the Jet Reports Excel add-in
Microsoft 365 installations of Excel 2016 feature the AutoSave feature.
This feature is fully compatible with the Jet Excel add-in. Because AutoSave works "behind the scenes" to save your file every few seconds, it is possible to save modifications over a file that you did not intend to change.
If you do not want to save changes to an important file, you can turn AutoSave Off for a file, and Excel will remember to keep it off every time you reopen that file.
