How to pretty json output from curl?

Question

I am trying to do this:

curl localhost:3000/api/items/15/tools

This is the return right now:

{"recipe_tools":[{"id":19,"name":"Cutting Board","prices":{"display":"$49.99","value":"49.99"},"description":"Built to last,
... (and then like a million lines)

And it keeps going...

How do I pretty print or awesome print this? What can I do?

Within curl? You can't; it doesn't. There are plenty of tools you could pipe some JSON into and format it though. As such, I would suggest this is actually a software recommendation request. — Sobrique

There are things you can install, but the simplest way is to use Python as it's typically already installed.

curl localhost:3000/api/items/15/tools | python -m json.tool

I use jq to pretty-print it.

jq is a lightweight and flexible command-line JSON processor.

jq is written in portable C, and it has zero runtime dependencies.

E.g.

Without JSON formatter

$ curl -s http://localhost:3000; echo
{"account":{"id":"HXRC","uri":["mailto:[email protected]","tel:366-643-7219"],"features":["585"],"nickname":"Consultant"}}

Install jq(Ubuntu):

$ sudo apt-get install jq

Use jq json formatter.

$ curl -s http://localhost:3000 | jq '.'
{
  "account": {
    "id": "HXRC",
    "uri": [
      "mailto:[email protected]",
      "tel:366-643-7219"
    ],
    "features": [
      "585"
    ],
    "nickname": "Consultant"
  }
}

You can find more examples in tutorial. You can find the installation for each OS in download page

jq is also available through Homebrew, so brew install jq

Port 3000 makes me think you are using Rails.

I have used JSON.pretty_generate(json_obj) on my RoR applications to have a JSON object return properly indented.

On macOS, use json_pp

Example:

curl your_request_url | json_pp
