CODINGNOW JSON Formatter
Format, validate & explore JSON — 100% in your browser
A free, single-file JSON formatter, validator and tree viewer. Pretty-print or minify, jump to the exact line:column of any error, and browse big JSON in a collapsible, color-coded tree. Everything runs in your browser — no upload, no signup, no ads.
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.
