Generate XLS File from Page List in Pega PRPC

I’m working in PRPC 7.x; I need to generate an xls file with two worksheets each of which is basically just information copied from each of two page lists.

We don’t have any jars aside from default PRPC, which means we don’t have apache poi. We do have access to iText, I am unfamiliar with the library but am informed it may have potential use here.

Is there a way in PRPC to generate simple XLS files with a high degree of control?
