How to Export "text" data type data from PBCS ASO plantype in columnar format

Summary:

I need to Export "text" data type data from PBCS ASO plantype in columnar format

Content (required):

I already can export numeric data with Data management, but it doesnt export "text" data.

Although I found a way to export text data from a PBCS ASO using REST data sclices export, that generates a Json file (which I tried to convert to columnar format without sucess).

Is there another method to export text data in columnar format or a method to effectively convert the data slice export to columnar?
