JSON Toolbox by mackan.eu
Format, convert, repair, compare JSON in your browser
JSON Toolbox is one page that replaces three or four separate sites: format and minify JSON, validate it, repair broken JSON, diff two documents to see what changed, and convert between JSON and CSV, XML, or YAML. Everything runs client-side in the browser, so pasted JSON, whether it is an API response, a config file, or anything else sensitive, is never uploaded to a server. No signup, no ads, dark mode included.
I built this after switching between three or four different JSON sites in the same debugging session: one to format, another to diff, another to convert. JSON Toolbox puts all of that in one tab, and none of it touches a server. Open the network tab while you use it, nothing fires.
It is free, with no account and no ads. I maintain it myself, so feedback and feature requests are welcome.
