Hey Product Hunt! 👋 I built jsonfmt.dev because I was frustrated with existing JSON tools — they're either bloated with ads, require an account, send your data to a server, or just look terrible. My goal was simple: the fastest, cleanest JSON tool that works entirely in your browser. No backend. No tracking. No data ever leaves your machine. What started as a formatter quickly grew as I kept...
jsonfmt.devFormat, validate, diff, convert JSON. 100% client-side.
Instantly format, validate, minify and beautify JSON online. Tree view, diff, JSON→YAML/CSV/XML, JWT decoder, repair. Free, no signup, works offline.
