    You may consider and try below approach using BigQuery’s REGEX_EXTRACT function.

    with sample_data as (
  select "{"name": "Charles Darwin", "email": "[email protected]"}" as my_string
)

select REGEXP_EXTRACT(my_string, r'"name":(D+),') as ext_name,
REGEXP_EXTRACT(my_string, r'"email":(.+)}') as ext_email
from sample_data

    Sample Output:

    My sample REGEX is the most basic one since I am not familiar with your complete data. You may enhance or create your own REGEX that can fit your needed validation based on your own analysis on your data.
