Hey Product Hunt! 👋
I’m the creator of LocalJSON. I built this micro-utility because I was deeply frustrated by the lack of secure, privacy-focused data tools that don't compromise client information.
LocalJSON was designed to be purely frictionless—no heavy servers, no forced logins, and no data tracking. Just paste your JSON, map your structure, and get your clean data out.
I’m online and would love to hear your thoughts, feature requests, or any use cases you’d like to see supported next. Thank you so much for the support! 🚀
