Notice how the functions require both a reference to the `String` column `tags` and a path in the JSON to extract. Nested paths require functions to be nested e.g. `JSONExtractUInt(JSONExtractString(tags, 'car'), 'year')` which extracts the column `tags.car.year`. The extraction of nested paths can be simplified through the functions [`JSON_QUERY`](/sql-reference/functions/json-functions#JSON_QUERY) and [`JSON_VALUE`](/sql-reference/functions/json-functions#json_value).

Consider the extreme case with the `arxiv` dataset where we consider the entire body to be a `String`.
