Get all values in a column. Returns column letter and values with row numbers.
AI agents call get_column to retrieve information from Google Connections without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from a Google Sheets column without modifying, creating, deleting, or executing any operations. It is a pure read operation with no side effects. The low severity reflects minimal risk even if misused by an AI agent—at worst, it could expose data the user already has access to.
