How to get straight table values or table data into an variable in Qlikview ? As I am going to use the table data in Javascript fetched through variable and generate PPT reports using pptxgenjs library.
Use something like let MyVar = peek(...) (see documentation for peek() here).
If you need to merge values from multiple fields you should do that first using the scripting function concat() to load those values into a string in a new (temporary) table, and use peek on that table.
