Given that AppSheet now has App Script workflows, I'm hoping there will be a new Behavior for exporting current view, but instead of to CSV, to Google Sheet.
For organizations that are generally using Google Environment (and requesting MS Excel needs justifications), Exporting to CSV will pose limitations to users who want to work on the subset of files on a separate Google Sheet (since no Excel).
There is probably a way to do this via App Script call, but I'm not sure how to pass the current view only to the App Script as the parameter.
