Import into Excel

[netaps]

I have a Java appliction running and this application needs to call Excel and probably fire off some script in Excel which imports the comma delimited file into a worksheet. However, the Java application keeps getting these comma delimited files every day, and the application needs to import this data and save it in the same worksheet but in different sheets day-wise.

I do not know VB, can you help me with the VB script to do this?
