Easiest way to compare two Excel files in Java?

Question

I\'m writing a JUnit test for some code that produces an Excel file (which is binary). I have another Excel file that contains my expected output. What\'s the easiest way to com

Answer 1

Maybe... compare MD5 digests of each file? I'm sure there are a lot of ways to do it. You could just open both files and compare each byte.

EDIT: James stated how the XLS format might have differences in the metadata. Perhaps you should use the same interface you used to generate the xls files to open them and compare the values from cell to cell?
