I m launching CSV Cleanroom tomorrow: a small, offline browser tool for cleaning messy CSV exports without uploading sensitive files. It detects delimiters, normalizes headers, trims whitespace, removes blank and duplicate rows, and previews the result before export.

I deliberately kept it local-only, with no telemetry or account requirement. For people who regularly handle CRM, payments, survey, or operations exports: what would you need to see before trusting a CSV cleaner with real business data? I d especially value feedback on the default cleanup rules and which edge cases matter most.
