At work, we deal with huge, messy JSON files every day, and I realized this frustration can’t be just mine—there must be a lot of devs facing the same thing.
So I built zeroformat.com.
Right now, it has:
JSON Viewer
JSON Formatter
JSON Validator
Simple, fast, clean UI — no login, no registration, just open and use it. Plug-and-play.
I’m actively building more tools, and honestly, if it grows — great. If not, my team and I will still use it daily But if you work with JSON often, I’d genuinely love for you to try it and share feedback.
In case you are busy and directly want to try the tool ,

If it helps you even a little, that’s a win.
