Hello,
To export data in qListView to an Excel document, please enable the Show Export Button property under Toolbar Appearances to enable the item in the toolbar of qListView.
Now you can select Export from the Action menu, which will open a panel that lets you configure your Export options.
Please try these steps for exporting a basic qListView. If it does not work properly, please provide some details of how the web part and cross-referenced list are set up, so that we can provide further assistance.
Thanks,
Yuan
