Export (already loaded) LookUp table from Revit Family to desired directory based on LookUp table name

Hello, I am looking for a way (Dynamo / Python custom node) how to open a list of Revit Families in the background, export the existing LookUp table located in the family, and save it to the desired directory based on the lookup table name (there are multiple lookup tables in the families).

There are multiple ways how to export almost everything from Revit to .csv, also you can import/load new csv to the family, but I did not find any package or custom node to simply export the existing LookUp table out of the family.

Unfortunately, my Python knowledge is not sufficient, but it is supposed to be possible…
From revitAPI:

class FamilySizeTableManager(object,IDisposable):
def CreateFamilySizeTableManager(document,familyId):
def ExportSizeTable(self,tableName,filePath):

Revit 2018, Dynamo 2.04

@martin.javurekNHUTZ , hi

Its a bretty old version. Normaly i would say use package datashapes…

Hi @Draxl_Andreas

Thank you for your reaction, I have datashapes package, but i did not find anything what could solve my task. What nodes you had on your mind please?

Looks like you need to build your own exporter, as per here: Solved: Re: Exporting Type Catalogs using the api - Autodesk Community
