Inventory replenishment — self-initiated Excel demo with fictional data.

Eight SKUs: six ready and two flagged for review. The valid rows propose 45 units across two items. Available stock accounts for reservations and inbound quantities. Missing, negative, fractional and duplicate-key inputs remain visible for review.

Editable workbook with formula-driven reorder quantities. Checks covered input changes, zero versus blank, duplicate keys and restoration of the sample values.

AI-assisted implementation. This is a working demonstration, not client work. Formula and visual checks passed; native Excel application testing was not performed.
