Launching today: CSV cleanup without uploading your data

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/products/csv-cleanroom?launch=csv-cleanroom
