thanks for you email.

Translated csv to JSON, read it as a plain text file and then processed to 
objects. 
It solved my use case.

Hi,

    The CSV only supports the types listed in [1] and must use the types in 
this list, thus for other types some kind of workaround is needed, like first 
parsed as string and parsed again later in the program. 

Best,
Yun
