Sql Extract Data From Complex Json In Big Query Stack Overflow You need to change the keys in order to be able to extract them properly. this key, f.e, "% features with post matching smd < 0.1" is not going to work with the json extract function, as you can see here:. This post will guide you through the process of parsing complex, nested json and transforming it into structured, queryable data within bigquery’s nested columns.

Extract Data From Json In Bigquery Stack Overflow I was asked today about dynamically extracting key value pairs from heterogeneous json like strings in bigquery sql and i've remembered this interesting approach i've seen a while ago. Dealing with unstructured or semi structured json data can be more challenging than working with structured data, as it requires additional efforts for data cleansing and extraction. Recap: we can use the json extract scalar function in standard sql bigquery to parse json data and extract values from it using jsonpath expressions. this enables us to work with complex json data in bigquery and extract meaningful insights from it.
