Tribix - Extended Emitters for BIRT

Hi, I´ve installed xls emitter 2.3.1 on BIRT 2.3.2. It´s working fine but I noticed that, when I have string values that start with zeros, those zeros are removed from the string when they are exported to Excel. For example, code "0A24" is shown as "A24", "0087" is shown as "87". I need those codes be shown as they are, with the zeros on the left.

Any suggestions?
