Automate CSV Import/Exports without Models

If I open Monarch, load a CSV without a model and export it it to Excel, it works perfectly right out of the box.   Headers, field types - everything is perfect.    I'd like to do this using automation.    The problem is that, if a model isn't defined, nothing is output.

Of course I can do this with libraries and other products and heavy lifting but Monarch is already doing it perfectly.   My objective is to be able to just use Monarch as a CSV to Excel converter that makes the header a little nice and preserves our customer numbers (which Excel always butchers).

Any workaround ideas?
