What is JSON Toolbox by mackan.eu?

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.
