I will automate CSV data cleaning with a reusable python script

Turn a recurring CSV cleanup task into a reusable local Python script.

Basic package: one CSV layout, up to 100 data rows, 10 columns, 25 MiB and five agreed rules. Delivery in 3 days, with one revision within the agreed scope.

Supported rules include whitespace cleanup, required-field checks, exact duplicate removal, and date or decimal validation. Invalid records and conflicting IDs are separated into an audit file with reasons. Missing values are never invented.

You receive Python source, configuration, clean CSV and JSON output, an audit log, a summary and run instructions. The script runs locally with Python 3.8+ and needs no paid API. You can reuse it for the same file structure.

Development is AI-assisted. Please message me with 10-20 anonymized sample rows, your cleanup rules and expected output before ordering. Send only data you are authorized to share.

Native Excel files, OCR, integrations and ongoing support require a separate scope review. The demo uses synthetic data. Communication is in Chinese, with translation assistance for English messages.
