Turn messy CSV/XLSX exports into a reconciled, repeatable workflow.

Deliverables • Cleaned workbook or CSV output • Duplicate, invalid-row, and warning log • Documented normalization rules • Reusable Python or Node.js automation script • QA report with row-count reconciliation and machine-readable receipt • One revision plus concise handoff notes

Defined scope • Up to 5 input files and 50,000 total rows • One agreed output schema and file format • Work starts only after the order is funded and sample/exported inputs are supplied • Delivery within 5 business days

Done means the output reproduces from the supplied script, source and output row counts reconcile, and the agreed validation checks pass. Before ordering, message the input formats, required output, and deadline so I can confirm fit.
