Turn a recurring CSV export into a cleaned file, a separate report of rows that need review, and a reusable Python script for future exports with the same columns and agreed rules. Originals stay unchanged. Input/output reconciliation counts and automated checks help you verify the results. Starter scope: US$60 service fee for one UTF-8 CSV, up to 100 rows and 10 columns, with up to three agreed cleanup or validation rules and one in-scope revision. Target delivery is within five days after scope and inputs are agreed. Any platform fees are shown separately by Contra before payment. Message first; this is not an automatic order. Deliverables: cleaned CSV, row-level exceptions report, input/output reconciliation counts, reusable dependency-free Python script, automated checks and a short run guide. Rules can cover exact duplicates, whitespace, agreed date formats and required fields. Missing or conflicting facts are flagged rather than invented. To confirm fit, send column names, row count, desired output and a small synthetic or redacted sample. We agree acceptance checks, total price and delivery date before work begins. Larger files or additional rules are quoted separately. Profile examples are independent synthetic portfolio projects, not client engagements. Confidential data and AI tool use require prior client agreement. No production access, live CRM imports, fuzzy identity matching, guessed corrections or regulated personal data.
