Clears values from a range in an Excel-format file (.xlsx or .xls) on Google Drive. Similar to clearSpreadsheetRange but preserves Excel format.
AI agents call clearExcelRange to permanently remove resources in Google Workspace MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing data from a range is an irreversible operation — once values are erased, the original content cannot be recovered without a backup or version history. This goes beyond a simple write/update and constitutes destructive data removal, potentially affecting large datasets across spreadsheet ranges.
