Get a cleaned CSV and a clear record of every change. I use AI-assisted tools to tidy agreed fields, remove identical full-row duplicates and flag records that need your decision. Your original file stays intact, and leading-zero IDs remain text.

Included for $75: one UTF-8, comma-delimited CSV with up to 5,000 data rows and 15 columns; agreed whitespace and case cleanup; exact full-row deduplication after cleanup; checks for one ID column and up to two YYYY-MM-DD date columns; one revision within the agreed rules.

You receive the cleaned CSV, unchanged source, change log, duplicate-removal log, review list and a summary reconciling the input and output counts.

Please message before starting with a redacted sample, row/column counts and the required cleanup rules. Scope and delivery date are confirmed after review. The listed one-week window starts after the scope is accepted and the source file is received. AI-assisted processing is subject to your permission and data requirements.

Not included: fuzzy identity matching, guessing missing values or ambiguous dates, email verification, web scraping, Excel workbook repair or live database integrations.
