Explanation

STRIP_NULL_VALUE is the Snowflake function specifically designed to convert a JSON null (a valid JSON value of type null) into a SQL NULL. JSON null and SQL NULL are semantically different - JSON null is a typed value within a VARIANT, while SQL NULL represents the absence of a value. TO_CHAR and TO_VARCHAR convert values to strings, and TO_VARIANT converts a SQL value into the VARIANT type. None of these perform JSON-null to SQL-null translation.
