Как выгружать данные с вложенной структурой из Google BigQuery на примере пользовательских параметров Google Analytics

Why not to run simple query? You can easily join nested objects to parent rows

SELECT ...
FROM FROM `project.dataset.tablename` AS t
LEFT JOIN t.customDimensions tcd

I showed one of the methods that I use myself. For example, you can also use UNNEST or your method.
