$ pretty-color-json < joke.json > joke_formatted.json

  "icon_url": "https://assets.chucknorris.host/img/avatar/chuck-norris.png",
  "id": "A7jUZR5wTZGvV-jtyIphOw",
  "updated_at": "2020-01-05 13:42:26.991637",
  "url": "https://api.chucknorris.io/jokes/A7jUZR5wTZGvV-jtyIphOw",
  "value": "Chuck Norris once ran a quarter mile in 3.7 seconds, while pulling an 18-wheeler in wet cement."
}

Note

This by default prints JSON like a JavaScript object literal which the keys are no longer wrapped with quotes, therefore the output will no longer be a valid JSON. Use json-format-cli or output to a file instead for formatted valid JSON.
