About this product

Turn messy CSV exports into import-ready files in one local command.

CSV Cleanroom trims whitespace, normalizes emails and phones, removes blank rows and duplicate records, and writes a JSON report showing what changed. It runs on Python 3.9+, makes no network requests, and never uploads your data.

Included: a dependency-free Python utility, quick-start documentation, a synthetic sample CSV, a smoke test, and a commercial-use license.

Download the ZIP and run: python3 csvcleanroom.py messycontacts.csv

Your source CSV is never overwritten. Review the output before importing it elsewhere.
