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/

CSV GB+ gives you a fast, point-and-click interface built on dual backends (memory-optimized or disk-backed) so you can process huge datasets offline. Key Features: Handles massive CSVs with ease — merge, split, dedup, filter, batch export Smart engine switch: disk-based "V Core" or RAM-based "P…
