What command is used to remove the outer array structure when loading JSON files?

1. REMOVE_OUTER_ARRAY

2. STRIP_OUTER_ARRAY

3. ELIMINATE_OUTER_ARRAY

4. FLATTEN_ARRAY

The correct answer is: STRIP_OUTER_ARRAY

The command to remove the outer array structure when loading JSON files is known as STRIP_OUTER_ARRAY. This function is specifically designed to handle JSON data that may be structured in an array format. Organizations often encounter JSON files where the data is wrapped in an outer array, which needs to be unpacked to facilitate individual record processing. By utilizing the STRIP_OUTER_ARRAY command, the outermost array brackets are eliminated, allowing seamless access to the individual objects or records contained within. This is especially useful in scenarios where data is ingested into systems that expect a structured record format, rather than an array of records. The other terms mentioned do not correspond to actual commands within Snowflake, which is why they do not fulfill the requirement of removing the outer array structure. Understanding the correct usage of STRIP_OUTER_ARRAY enhances data ingestion processes and aids in managing JSON data effectively in Snowflake environments.
