If you work on backend systems, APIs, or integrations, you probably spend more time staring at JSON than you’d like to admit.
I do too.
And honestly, that’s where the frustration started.
Most JSON tools I tried were either:
unreliable on Windows,
painfully slow with large payloads,
or had a UI that made debugging harder instead of easier.
At work, we regularly deal with large, deeply nested JSON, and jumping between tools just to view, format, and validate became a daily tax on productivity. After a point, I stopped searching and decided to build something I’d actually enjoy using.
What I built
I built https://zeroformat.com
— a lightweight, browser-based tool focused on doing a few things really well:
🔍 JSON Viewer
✨ JSON Formatter
✅ JSON Validator
No login.
No registration.
No setup.
Just open the site, paste your JSON, and get on with your work.
Why another JSON tool?
Because sometimes tools don’t need to be “feature-rich” — they need to be fast, clean, and predictable.
This isn’t a startup pitch or a growth hack experiment.
Even if no one else uses it, my team and I already do — daily.
That said, if it helps you even a little, I’d love for you to:
try it,
break it with real-world data,
and share feedback or feature ideas.
What’s next?
I’m planning to add more developer-centric utilities over time, based on actual pain points rather than trends. If this resonates with people, I’ll keep building.
If not, that’s okay too.
Either way, here it is:

Would love to hear what JSON tools you currently use — and what annoys you about them.
