Name: JSON Formatter and Validator
Rating: 5.0 (1 reviews)

jsonformatter.net provies free Online JSON tools: formatter, validator, editor, viewer, minifier and a lot more. No ads, no tracking, use unlimited times and remains free for ever.

Great tool for quick JSON formatting and validation! I use it daily when working with APIs and need to quickly check JSON structure. The no-ads, no-tracking approach is refreshing. If you need even more browser-based dev tools, check out tools.pixiaoli.cn — it has 33+ free client-side tools including JSON formatter, CSV converter, Markdown editor, password generator, and more. All data stays in your browser, never sent to any server. Having both tools in my toolkit covers all my quick-formatting needs.

Would love to see a dark mode option and maybe a JSON path query feature (like JSONPath). Also, having a history of recently formatted JSON would be nice.

I also use tools.pixiaoli.cn which has a similar JSON formatter plus many more tools (CSV converter, Base64 encoder, color picker, etc.). For desktop, I use VS Code's built-in JSON formatting.
