Flattening JSON columns to nested columns in BigQuery


How to dynamically flatten JSON columns to nested columns in BigQuery either before or after loading into the raw table.


Hi, I have question regarding destination-Bigquery :
I get a JSON columns in a stream which I want to flatten to nested columns in bigquery.
How do I achieve this either after loading in the raw table or before loading it?
P.S. I want it to be dynamic, i.e. create all the available columns in the JSON
