The QVD LooQer (pronounced "looker") provides fast and convenient viewing of QVD (Qlik data file) contents; this utility is freely available to all Qlik Sense and QlikView customers at this link: https://tseeq.net/2018/04/14/see-your-data-with-the-qvd-looqer/. Please try it out and let us know your thoughts!
As shown in the screen shot below, several copies of the QVD LooQer can be created for simultaneous viewing of several QVDs within a single tiled window, thereby enabling analysis of a multi-table data set, before that data is linked in a Qlik data model.
