Maker here 👋 I built this because I disliked pasting API responses (often with tokens) into JSON formatters that upload to a server. This one does it all client-side: format/minify, validation that points to the exact line:column, a collapsible tree view, copy/download, drag-and-drop. Single static HTML, zero deps. It's one of a few free, no-signup tools I make (image converter, audio cutter, QR generator). Would love your feedback — especially edge cases in the validator.
