Snowflake Querying Semi-Structured Data Documentation (2026)

Official Snowflake documentation for VARIANT and semi-structured data querying.

Key facts surfaced (2026-05-19):

• Dot notation (e.g., src:salesperson.name) and bracket notation for nested structure traversal.
• FLATTEN function explodes nested values into separate rows; supports recursive discovery of all keys.
• Higher-order functions FILTER, REDUCE, TRANSFORM with lambda expressions streamline array manipulation.
• Supports JSON, Avro, ORC, and Parquet source formats.
• Curriculum reference: composable CDP equivalent of AEP dot-notation XDM field access for GA4 BigQuery export normalization (Module 12).
