Qlik Sense : Export In-Memory Loaded tables without data source

Hey Guys, had a question. I have a qvf file which contains a set of visualizations in the sheets. I dont have the data source for this qvf file with me, and I want to somehow export the in-memory tables out. I tried adding a section to my qvf file data load editor section

TRACE Number of tables: $(NoOfTables());
FOR i = 0 to NoOfTables() - 1
