The JSON debugging tool I always wanted
Ever spent 30 minutes debugging a JSON parsing error only to find it was a missing comma? Yeah, me too. That's why I built this JSON Formatter. It's not just another online tool—it's the debugging companion I wish I had when I was knee-deep in API integrations and microservice configs.
My daily workflow with this tool:
- Validating webhook payloads before processing them in production
- Converting API responses to YAML for Kubernetes deployments
- Minifying large JSON datasets for faster API responses
- Beautifying legacy config files that look like they were written by a cat
Pro tip: Use the validator before deploying any JSON-based config. A single syntax error can bring down your entire service. And always convert to YAML for Kubernetes—it's just more readable than JSON for configs.
Built this because I was tired of context-switching between different tools. Now everything happens in one place, client-side, with zero privacy concerns. If you're dealing with JSON daily, this should save you hours.
