Excel's undo dies when you need it most
Excel's built-in undo (Ctrl+Z) has severe limitations. Close the workbook? Undo history is gone. Run a macro? Undo history is cleared. Save the file? Many operations become unrecoverable.
The most painful loss: deleting a worksheet. Excel warns you with a dialog, but once confirmed, there is no undo. If you accidentally delete a sheet with hours of work, it's gone — unless you have a backup file from before the deletion.
For power users who work with macros, this is especially frustrating. A single macro run wipes the entire undo stack, meaning you can't undo any changes made before the macro ran.
The Solution
Snapshots that persist across sessions
Smart Undo creates document-specific snapshots that persist in IndexedDB on your machine. Your undo history survives saves, macro runs, and even session restarts.
If a worksheet is deleted, you can restore it from the most recent snapshot — complete with all cell values, formulas, and formatting. No need to hunt for backup files.
The free tier keeps your 5 most recent operations. Pro users get up to 100 operations, with older ones automatically removed to manage storage.
