JSON Formatter & Validator - Professional online json tool | format, validate & convert

🚀 We’re Live! Hey Product Hunt! 👋 I’m excited to launch JSON Formatter & Validator — a fast, lightweight, and distraction-free tool to format, validate, and beautify your JSON in seconds. Why I built it: I often found myself juggling between different JSON tools, some overloaded with ads or unnecessary features. I wanted something blazing fast, privacy-focused, and simple enough to use every day. Key features: 🔹 Instant JSON formatting & validation 🔹 Error highlighting with line numbers 🔹 Works 100% in your browser (no data sent to servers) 🔹 Dark mode for late-night debugging 🔹 Mobile-friendly interface What’s next: I plan to add JSON minifying, syntax highlighting themes, and maybe even a shareable JSON link generator. 💬 I’d love to hear your feedback — especially any ideas for features you’d like to see next!
