Rule-based cleanup of one CSV file with up to 1,000 data rows and 10 columns. The $15 package includes agreed whitespace trimming, exact duplicate removal, consistent labels, and unambiguous format standardization. I preserve the original file and flag missing or ambiguous values for clarification. Delivery includes a cleaned UTF-8 CSV, a short change summary, and one revision within the agreed rules. Please send the file, column definitions, cleaning rules, and deadline before ordering. Timing is confirmed after review. This package excludes data scraping, enrichment, statistical modeling, and complex workbook repair. Samples use original fictional data.
