Hi, I am using duckdb for transformation and i am having custom column with json values. I need to convert that column into many column based on the json values for every rows. Please can anyone suggest solution. Is there any inbuilt to flattern that column into many.

Have you seen https://duckdb.org/docs/extensions/json.html#json-extraction-functions? I'm not sure whether there's a way to extract all keys into columns automatically, though_._
