Sales Data Cleanup — self-initiated demo using fictional data.

27 inputs = 18 clean records + 2 removed duplicates + 7 held exceptions. Accepted sample sales: USD 658.50 (fictional data, not income).

Deliverables: editable Excel workbook with Result, Raw and Exceptions sheets; repeatable Python cleaner; clean, exception and change-log CSVs.

Rules preserve the original, remove exact normalized duplicates, hold all conflicting IDs, and flag missing or ambiguous values.

Seven automated checks passed; formula recalculation and rendered workbook views checked. Native Excel application testing was not performed.

AI-assisted implementation. This is a demonstration, not a previous client engagement.

Messy books in. Clean books out. 📊

This is a simple before/after of a bank reconciliation (sample figures, no client data). Before: a duplicate payment and a missing entry left the books out by KES 13,650. After: both fixed, and the difference is KES 0.00.

This is the kind of work I do for small businesses every month: ✅ Bank and account reconciliations ✅ Accounts payable and receivable ✅ Invoice and payment processing ✅ Month-end support and financial reporting
