Hey Product Hunt! We're Nomos Insights, and we built JSON Operations because we were tired of pasting sensitive API responses into random online tools that quietly send your data to their servers. Here is what JSON Operations does differently: Every single operation runs 100% in your browser. Your data never touches a server. No cookies. No analytics tracking your JSON. Nothing leaves your machine. The toolkit includes: - JSON Formatter with beautify, minify, stringify, and tree view - Real-time validation with line-level error highlighting - 9 converters: JSON to/from CSV, XML, YAML, Table, TOON, and a mock data generator We built this for ourselves first. Our dev team uses it daily for debugging API responses, cleaning config files, and converting data formats for client projects. After months of internal use, we decided to make it available to everyone. No signup. No freemium tricks. No "upgrade to unlock" walls. Just open the site and start working. I would love to hear what tools or converters you would want us to add next. We are actively building and shipping new features. Try it: https://jsonoperations.com
