What's coming next
Items on the public roadmap, in rough priority order:
- Native iOS and Android apps (with In-App Purchase unlock)
- Delimiter selector (tab, semicolon, pipe)
- Encoding selector (UTF-8, ANSI, ISO-8859-1)
- Column type assignment (number, currency, date, email)
- Deduplication tool
- CSV diff between two files
Some of these may live in higher-tier subscriptions in the future. Your current Pro plan stays included for everything in this list above.
