Thanks, Syaman, for this add-in. It worked great for me.
You can get the add-in by looking at Syaman's post from January 11, #447923. In the title bar of the post will be an Attachment link. Follow that to download a .zip file with the add-in in it.
I just installed the add-in in Office XP, and it worked with QC 9.0 patch 18. These are the steps I took to install the add-in:
Unzip the 447923-QC2Excel.zip file. Copy the QC2Excel.xla add-in file to your C:\Program Files\Microsoft Office\Office10\Library directory. Launch Excel. In Excel, select Tools -> Add-Ins... Ensure that the "Export To Excel v1.1" entry is checked. Click OK. Select Tools -> Export To Excel to run the export.
