Answer: SnowSQL

The PUT command is specifically designed for staging local files to Snowflake internal stages, and according to Snowflake documentation and the community consensus (with 100% agreement and multiple upvoted comments), this command can only be executed from SnowSQL. The Snowflake web interfaces (both classic UI and Snowsight) do not support the PUT command directly, as they operate within the browser environment and cannot access local file systems. While the .NET driver might theoretically support file operations, the question specifically asks about interfaces, and SnowSQL is the primary and documented interface for using the PUT command to stage local files.
