CSV Cleaner

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/

  • I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

    Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
