Sheets

Google Sheets and Microsoft Excel governance for AI assistants. These rules block spreadsheet formulas that exfiltrate data to external URLs (IMPORTXML / IMPORTDATA / IMPORTRANGE / WEBSERVICE) and require approval before an agent deletes a sheet or clears cells — the controls a non-technical user wants when an AI app is connected to their spreadsheets over MCP.
