CSV Cleanroom is live on Product Hunt today. It runs entirely in the browser and cleans messy CSV exports without uploading customer or business data. It detects delimiters, normalizes headers, trims cells, removes blank and duplicate rows, infers column types, and previews the result before export.
There is a free 25-row demo, and the complete offline version is $12 as a one-time purchase. No account, subscription, telemetry, or internet connection is required.
I built it for the repetitive cleanup that follows CRM, payments, survey, and operations exports. I would genuinely value feedback on the defaults and the edge cases that matter most: https://www.producthunt.com/prod...
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.
CSV Cleanroom is a private, offline CSV cleaning utility. It detects delimiters, normalizes headers, trims whitespace, removes blank and duplicate rows, infers column types, and exports Excel-friendly UTF-8 CSV files. Everything runs in your browser, so files never leave your device.
