CSV Deduper
100% Private B2B CSV Lead List Cleaner via Telegram
Ultra-fast B2B CSV Deduper & Lead List Cleaner built on Rust + WebAssembly.
I built this tool because I was tired of uploading sensitive lead lists and B2B data backups to random websites just to clean duplicates. This is a Telegram Mini App powered by pure Rust + WebAssembly.
Why use it? • 100% Private: Zero backend. Processing happens strictly inside your device's WebView. Your data never leaves your chat. • Blazing Fast: Thanks to Rust compilation, it handles large CSV files easily on the fly without lagging your phone. • No Signup: Launch right inside Telegram and clean your files in seconds.
I'd love to hear your feedback on the performance and UI. Give it a spin at t.me/csv_deduper_bot
