Pretty Print JSON

How to use Pretty Print JSON

1. 1. Paste minified JSON. Or drop a .json file from logs or curl output.
2. 2. Pretty print. Pick indentation, then copy from the formatted pane.
3. 3. Explore structure. Open Tree view for nested objects without scrolling a wall of text.

About this tool

“Pretty print json” and “format json online” are the same practical task: make machine JSON human-readable. This alias exists so the title and H1 match that query instead of a generic tool name.

Code examples

const payload = JSON.parse(raw);
console.log(JSON.stringify(payload, null, 2));

import json
print(json.dumps(json.loads(raw), indent=2, sort_keys=True))

var buf bytes.Buffer
if err := json.Indent(&buf, []byte(raw), "", "  "); err != nil {
  log.Fatal(err)
}
