My company uses a horrible SAP interface. I then had the complexity of making an Excel sheet that actually works, and making it properly interface with SAP so I only have to use the excel sheet.
As a SAP developer there are so many ways to read Excel sheets but they all suck in one way or another - SAP itself does that but it depends on which SAP module you are programming in (MM/FICO/EWM) so each module has a mediocre implementation to read in XLS.
Somebody got fed up and did a general purpose XLS import library, but some sites forbid you using it.
