CSV Tools Online

I’m super excited to share CSV Tools Online with you all — a privacy-focused, all-in-one toolkit built for developers, data analysts, and curious minds working with CSV, Excel, and JSON files. 💡 Why I built it: I was tired of bloated software and privacy concerns just to run a few SQL queries, join files, or generate a simple chart. So I built a toolkit that does all that — right in your browser, no logins, no uploads. -> What you can do: 🧮 Run SQL queries on CSVs 📊 Build charts instantly 🔗 Join CSVs like SQL JOINs 🧠 Build no-code ML models (regression/classification) 🔄 Convert JSON ↔ SQL, JSON diff 🎯 Create pivot tables And much more..... 🔒 If you want to verify it’s safe? Open DevTools → Upload a file → You'll see zero network requests. Everything happens on your device. Your feedback, upvotes, and suggestions mean the world! 🙏 Let me know what features you'd like to see next 🚀 Explore now → https://csvtoolsonline.com/tools
