Anybody know if there's a way to import account codes from a CSV file???

I know this is an old post, but no, you cannot import account codes from a CSV file. Sharp uses their own .bin file system.

Now if you were to create 1 code and export that file, open it in notepad and see the layout, then copy the needed info from the csv file to the bin file and then import the bin file, that may work. I have done it a few times and although labor intensive, the customer is happy.
