Clear values in a specified range of a Google Sheets spreadsheet
AI agents call sheets_clear_values to permanently remove resources in Mcp Gsheets — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing cell values in a spreadsheet destroys the data in those cells. Unlike an update/overwrite that replaces content, a clear operation removes values entirely. This is irreversible through the API, making it Destructive. The blast radius is high because a misconfigured range could wipe large portions of a spreadsheet containing critical business data.
From the tool's definition 'Clear values in a specified range of a Google Sheets spreadsheet' — clearing values removes data from cells irreversibly (no undo via API)
