How to open Password protected Excel file in ubuntu 12.04?

Question

Previously I was using dual boot (Windows 7 and Ubuntu 12.04). At that time I created some Excel files with password protection. Now I am using only Ubuntu 12.04 and not Windows. iI want to open those files in Ubuntu. How can I do that?
