cardPresso has the ability to import data, however you will need to upgrade to the XS edition for Excel based files (.txt, .xls, .csv) or to XM edition for Microsoft Access files (.mdb). The main difference in these two databases is photo connection. Microsoft Access allows you to populate any given cell with an image, which cardPresso can then retrieve during import.
Above and Beyond
cardPresso even offers further versions (XL, XXL) for connecting to external databases via ODBC (Open Database Connectivity) so that you can retrieve all of your data with your current online database or local server.
