Hi,

There is currently not yet any general JSON writing functionality included in Arrow C++ (only the reading part), see https://issues.apache.org/jira/browse/ARROW-5033. So I don't think this is directly possible.

Best,
Joris

Hi~all
I can read the Parquet file to Arrow::table in c++ now, but have no idea how to convert them to the JSON file.

Is there any example to do that?

Thanks~
