Hi Product Hunt! 👋
I'm excited to share Format JSON Online, a simple yet powerful tool I built to help developers quickly format, validate, and minify their JSON data.
I created this out of my own frustration with bulky, ad-filled JSON tools. I wanted something clean, fast, and distraction-free — so I built it.
🔧 It works 100% in-browser
🌐 No sign-ups, no tracking
⚡ Super fast response even for large JSON payloads
🌙 Light & Dark themes for comfort
Would love your feedback, ideas, or feature requests — and if you find it useful, I’d truly appreciate your support ❤️
