About SheetGuard
SheetGuard is built by MotionTech LLC. We build tools that fix problems Microsoft has ignored for years in Excel — forced AI features, volatile undo history, no tab organization, and silent data loss from filtered edits.
SheetGuard started from a simple observation: Excel power users on Reddit consistently report the same pain points, and Microsoft has shown no intention of addressing them. The undo stack is volatile and shared across workbooks. Worksheet tabs have no grouping. Pasting into filtered data silently overwrites hidden rows. And Copilot was added without an off switch.
We built SheetGuard to solve these problems directly. The Excel add-in includes Tab Folders, Smart Undo, Filter Guard, and Hidden Row Protection. The free companion app blocks Excel Copilot at the Windows registry level.
Privacy by design
SheetGuard processes all spreadsheet data locally. Cell values, edit history, filter presets, and tab folder configurations never leave your computer. There is no cloud storage, no telemetry, and no analytics on spreadsheet content.
The only network requests SheetGuard makes are license validation pings that send a hashed key — never your data. Read our full Privacy Policy for details.
