24 alternatives to 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 built CSV GB+ by Data.olllo, a local data tool that lets you open, clean, and export gigabyte-sized CSVs (even billions of rows) without writing code. Most spreadsheet apps choke on big files. Coding in pandas or Polars works—but not everyone wants to write scripts just to filter or merge CSVs. 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…
