JSON to YAML

The purpose of this utility is to pretty-print JSON in the human-readable YAML object notation (ignore the misnomer, it's not a markup language at all)

You see, JSON is a proper subset of YAML, The difference is that YAML can use whitespace instead of syntax, which is more human-readable. Also, YAML supports comments.

So, for all the times you want to turn JSON int YAML (YML):

{
  "foo": "bar",
  "baz": [
    "qux",
    "quxx"
  ],
  "corge": null,
  "grault": 1,
  "garply": true,
  "waldo": "false",
  "fred": "undefined"
}

becomes

---
  foo: "bar"
  baz:
    - "qux"
    - "quxx"
  corge: null
  grault: 1
  garply: true
  waldo: "false"
  fred: "undefined"

Usage

Specify a file:

json2yaml ./example.json

yaml2json ./example.kml | json2yaml

Or pipe from stdin:

curl -s http://foobar3000.com/echo/echo.json | json2yaml

wget -qO- http://foobar3000.com/echo/echo.json | json2yaml

Or require:

(function () { "use strict";

  var YAML = require('json2yaml')
    , ymlText
    ;

  ymlText = YAML.stringify({
      "foo": "bar"
    , "baz": "corge"
  });

  console.log(ymlText);
}()); 

Installation

npm install -g json2yaml
