As one of the primary file types used by technologists it is so frustrating that people are still having to use the likes of XLSX or CSV to hold app configuration. XML is archaic.
https://community.qlik.com/t5/Suggest-an-Idea/JSON-File-type/idi-p/1667510 was my original post and I really do not think it should have been closed as the idea was nothing to do with exporting file format.
It is simply to add JSON files to the standard Load capability of Qlik Sense.
I remember listening to technology people in a previous job way back in 2014 saying they would not touch QlikView because of lack of direct JSON support. It is now 2021 and nothing has appeared for Qlik Sense, so again projects being promoted and managed by tech teams might question "why ?".
