Great tool to Qlik community.
The QV Convertor tool is available from the Dev Hub in QS 3.2+. It’s a pretty slick tool that converts QV Variables, Dimensions and Expressions to Master items and converts QV charts to Master QS Visualizations. It does not attempt to replicate the sheets, but expects you to place the visualizations on sheets yourself as required.
It’s a very useful tool with a good UI that allows for filtering and limiting what gets converted.
