I'm not sure if this is even possible, but if it is...

Is there a way to automatically create multiple packing slips or invoices
from excel data?

In my case, we can download a csv file with hundreds of customers' names,
addresses, and orders. I want a way to automatically create a packing slip
for each order (they can be on the same sheet, with page breaks) and print
the slip, instead of having to create a new packing slip manually for each
order. All the data is there.. I just need a way to create something out of
it.

We do this every morning, so something easy to use would be great.
