Not just QuarkXPress to InDesign. You can do it the other way around, too.
Another useful application from Markzware, ID2Q allows you to convert InDesign files to QuarkXPress files with ease. The only problme is that it only works for Macs, leaving the Windows users out of the equation.
ID2Q supports QuarkXPress 4.1 and 5 and can convert files to InDesign 1.0 and 2.0.
From Markzware:
ID2Q offers QuarkXPress users a quick and easy way to convert InDesign files into QuarkXPress documents. All elements of the InDesign document, including object positions, colors, text, text attributes, images, etc. are converted with a single click.
Companion products:
PM2Q5, convert PageMaker files to QuarkXPress 5.0 files.
Q2ID, convert QuarkXPress files to InDesign files.
