I will clean and validate one UTF-8 product catalog CSV (up to 1,000 data rows) and return three files: a cleaned CSV, a row-by-row issue log with reasons, and a short summary of what changed. Included checks: required SKU and product name, duplicate SKUs, price and stock formats when those columns exist, blank values, and malformed rows. I will confirm your column names and duplicate-handling rule before processing. The original file stays unchanged. Please send only product data you are authorized to share, or a redacted sample first. This offer does not include manual research, enrichment, API integration, scraping, or repair of unrelated database systems. One round of corrections to the agreed rules is included.
