JSON Viewer

Paste or open a JSON file and read it comfortably, with colors and line numbers.

● Your files are processed locally in your browser and are not uploaded to our servers.

How it works

The JSON is parsed, pretty-printed and colored: keys, strings, numbers, booleans and null each get their own color. Large files are displayed quickly because the work is done once, in your browser.
