WHAT IT DOES

RISK

Why freezeRowsAndColumns is rated Medium

This tool creates or modifies document state reversibly—freezing/unfreezing rows is a formatting operation that can be undone. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read). The ability to unfreeze (set to 0) confirms reversibility.

From the tool's definition The tool modifies document formatting state by setting frozen rows/columns (frozenRows parameter), which changes the visual presentation of the spreadsheet. This is a persistent change to the document structure, though fully reversible by setting values to 0.
