The very long name of this program, Excel IBM DB2 Import, Export & Convert Software, is enough to explain what it does.
It is a plug-in for MS Excel that lets you interact with IBM DB2 databases; in other words, thanks to Excel IBM DB2 you can both import and export tables from that database directly to Excel, and vice versa.
To use Excel IBM DB2 you don`t need any knowledge of MS Excel or SQL. For it to work correctly you need to apply it to MS Excel 2000 or later.
