CSV Cleaner▲3
Hi HN, I built a small utility to clean up messy CSV exports without opening Excel or writing pandas scripts. Upload a CSV → preview → choose columns to dedupe → normalize/trim → download the cleaned file. Free tier, no signup required for basic use. Stack: -Lovable for the app -Supabase (auth, Postgres, storage, edge functions) -Stripe for subscriptions/day passes Processing runs server-side; I kept the architecture intentionally simple and low-ops. Would love feedback on UX, edge cases, or features you’d want. Website: https://csv-cleaner.com/
