Description

JSON Operations is a free online JSON formatter, validator and converter toolkit that runs 100% in your browser. Your data never leaves your device.
It includes 10 tools: a JSON formatter with beautify, minify, stringify and tree view modes, a real-time JSON validator with error highlighting, and converters for JSON to CSV, JSON to XML, JSON to YAML, YAML to JSON, XML to JSON, CSV to JSON, JSON to Table and a mock JSON data generator.
Built for developers, data analysts and DevOps engineers who work with JSON daily. No signup required. No usage limits. No ads. No cookies. No backend. Completely free forever.
We built this at Nomos Insights because we were tired of pasting sensitive API data into random online tools that send everything to their servers. JSON Operations processes everything locally using client-side JavaScript.
