Hey Product Hunt! 👋 I'm excited to share Merge JSON with the community. The idea came from a simple frustration: whenever I needed to merge, validate, format, compare, or transform JSON data, I ended up jumping between multiple websites. Most tools either required uploading files, had limited functionality, or raised privacy concerns. So I built Merge JSON — a collection of 50+ free JSON tools in one place. Everything runs directly in your browser, meaning your data never leaves your device. No signup, no uploads, and no server-side processing. Current features include: ✅ JSON Merge ✅ JSON Validator ✅ JSON Formatter & Minifier ✅ JSON Compare ✅ JSON Converter Tools ✅ JSON Flattening & Transformation Tools ✅ And many more My goal is to create the most complete privacy-first JSON toolkit for developers, data engineers, QA engineers, and API teams. I'd love your feedback: Which JSON tool should I add next? Which existing tool can be improved? What workflows are still painful when working with JSON? Thank you for checking it out and supporting the launch! 🚀
