Hi, I'm Umesh. I'm working on a web based project which is written in Servlets and JSP's. My project allows clients to upload / download MS Excel sheets. I'm using MS Excel 2003 (.xls file format ) . But clients may be using MS Excel 2007/2010 (.xlsx file format) . So i need a solution in Java or a tool in Java to automate the task of converting *.xls to .xlsx and vice-versa.* ** I hope you will suggest me a good solution to this problem.
Thank You , Umesh
