Extracting field transformation from app load script [Qlik Sense]

[CariceHouten]

Is there a way, using the API, to retrieve the transformations applied to a field during the data load script?

For example:

MyTable:

LOAD num(mystringfield) as MyNumField

RESIDENT tmp_table;

I'd like to retrieve the final field name (MyNumField) as well as the transformation applied (num(mystringfield)).

I know some tools like Nodegraph do this kind of task (lineage) but we're not big enough to warrant such a tool and was also interested in trying it myself. I have been unable to find this information so far.

There is an API that you can call to get the script code for the app, conveniently named getScript. https://help.qlik.com/en-US/sense-developer/November2020/Subsystems/APIs/Content/Sense_ClientAPIs/Ca...

Parsing the code is why partners like NodeGraph charge for the tremendous amount of work that they have done handling all of the many transformation scenarios that Qlik handles.
