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.
