title: Split a JSON file into separate files
body: <p>I have a large JSON file that is an object of objects, which I would like to split into separate files name after object keys. Is it possible to achieve this using jq or any other off-the-shelf tools?</p>
  
  <p>The original JSON is in the following format</p>
  
  <p><code>{ "item1": {...}, "item2": {...}, ...}</code></p>
  
  <p>Given this input I would like to produce files item1.json, item2.json etc.</p>
