The quick answer is no.

Yes, you can convert the .xls spreadsheet to a CSV format. In this format, the
first row is your "header" or column row.
Note that all data is "text" data and is surrounded by ""s.
As to parsing the data, there's a bit of a snag.
Java's native string token parser ignores the \"s so that if you have a number
1,499.99 for example, it will get parsed as two separate fields. So you're
going to have to write your own. (Ok, so its a trivial problem...)
The negative thing about CSVs also include the fact that you no longer have a
viable excel spread sheet. So you'll have to "export" your spreadsheet to a
csv to work with.
Another option is to use a new class of objects that allow you to work with
native Microsoft data structures.
Again, here, you'll have to write your own code...
The bottom line, you'll have some work to do to so its not a simple "drag and
drop" type of activity
