This fictional 20-row sample includes inconsistent spacing and categories, leading-zero SKUs, missing values, a duplicate pair and ambiguous numbers and dates.
The workbook includes Original, Cleaned, Issues and Readme tabs. All 20 records and 120 original field values were preserved. Nineteen nonblank SKUs remained text with their leading zeros intact. Eleven issues were flagged for confirmation, including both duplicate records.
The workflow uses AI-assisted tools and scripted checks, comparison of the exported workbook against the source, and visual review of every sheet. Ambiguous values are left for confirmation rather than guessed.
This is a self-initiated demonstration, not a client engagement or a claim of sales results.
