Security and privacy notes

This plugin processes user-provided Excel/CSV files, performs local filesystem operations in temporary directories, stores parsed worksheet data in Dify plugin storage, and executes user-provided read-only DuckDB SELECT/CTE statements. It does not execute commands or send workbook data to third-party APIs beyond the Dify-provided file URL.

Local validation

• Package contents and ZIP integrity checked locally.
• Python smoke test could not run in this environment because the local Python executable session is unavailable.
• PR changes exactly one .difypkg file.
