Hi Product Hunt! 👋 I’m a software engineer who spent way too much time worrying about where my data goes when I use 'quick' online converters. We’ve all been there: you have a snippet of production JSON or sensitive CSV data that needs a quick reformat, and you paste it into a random site. The security risk is real. I built data-converter.app to solve this. It’s a 100% client-side tool, your data stays in your browser's memory and never touches a server. Key Features: 🛠 Privacy First: Pure client-side logic. 🌍 Multilingual: Supporting EN, ES, PT, DE, FR, and NL. ⚡ Next.js 15 Power: Optimized for speed and instant state changes. 🆓 Always Free: No accounts, no paywalls, just utility. I’m currently at a 17-hour 'quiet' period post-indexing, and I’d love for this community to be the first real humans to put it to the test. What formats should I add next? Any feedback on the UI/UX? I'll be here all day to answer your technical questions! 🚀
