Sure, this is the file type i tried to upload. After saving this file to my desktop I open up the ComicBase program I just purchased.
File
Import
Select this text file then select open
Then select these four fields to import. Title, Item #, Qty, Condition
I check to make sure the item separator is set to tab and not comma.
Then select import and hit enter.
Now, when I go to File, collection statistics, i get no comics in my collect but the file I imported contains 1555 copies.
