I will build a focused Python script that automates one clearly defined CSV or Excel workflow: cleaning data, merging files, transforming columns, validating rows or producing a structured export. The delivery includes readable code, setup instructions and a short verification on sample data. Please provide example files, expected output and any edge cases.
Attached English PDF: a synthetic catalog-cleanup example. From 24 input rows, 12 products are accepted, 3 are identical duplicates and 9 need review. Conflicting prices are kept for a decision. Five acceptance tests passed. The sample processor takes the documented CSV format; its XLSX report is a snapshot of that run.
