Turn messy spreadsheet exports into clean, reusable CSV files in seconds. This dependency-free Python toolkit normalizes column names, trims whitespace from every field, removes fully empty rows and removes duplicate records using either a chosen ID column or the complete row.

You receive reusable Python source code, a sample customer export, automated tests and a concise usage guide. The command prints an audit summary showing rows kept, empty rows removed and duplicates removed.

No subscription, API key or third-party package is required. Your data stays on your computer. Ideal for CRM exports, ecommerce customer lists, mailing lists, migration cleanup and spreadsheet QA. Requires Python 3.10+. Commercial use in your own workflows is allowed; redistribution or resale of the source is not included.
