Exports a sheet to CSV format
AI agents call export_sheet_to_csv to retrieve information from Smartsheet MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Exporting to CSV is a read-only operation that retrieves and transforms data into a portable format. It does not create, modify, delete, or trigger any side effects on the source data. The blast radius is low since misuse would only expose data rather than corrupt or destroy it.
