Hey hunters! 🎯 As a developer, I format JSON dozens of times a day—API responses, config files, debugging payloads. But I never felt comfortable pasting production data into online tools. So I built a JSON formatter that processes everything client-side. Zero data transmission. Features: → Format/beautify with customizable indentation → Validate with precise error locations → Compare two JSONs with semantic diff → Auto-fix trailing commas, missing quotes and common json problems → Generate TypeScript interfaces → Minify for production What JSON workflow problems do you face? I'm actively adding features based on feedback!
