yamlxjson

Note: These utilities were taken from https://github.com/coolaj86/yaml2json and https://github.com/coolaj86/json2yaml

They are combined into one repo / package with the latest changes published to npm.

Installation

npm install -g yamlxjson

yaml2json

A command-line utility to convert YAML to JSON (meaning a .yml file to a .json file)

The purpose of this utility is to minify YAML as JSON. (ignore the misnomer, YAML is actually an Object Notation, not a Markup Language)

Usage

Specify a file:

yaml2json ./example.yml

json2yaml ./example.json | yaml2json

Or pipe from stdin:

curl -s http://foobar3000.com/echo/echo.json | json2yaml | yaml2json

wget -qO- http://foobar3000.com/echo/echo.json | json2yaml | yaml2json

Example

---
  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"
}

Note: 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.

Alias

yaml2json has the following aliases:

• yml2json
• yamltojson
• ymltojson

json2yaml

A command-line utility to convert JSON to YAML (meaning a .json file to a .yml file)

The purpose of this utility is to pretty-print JSON in the human-readable YAML object notation (ignore the misnomer, YAML is not a Markup Language at all).

Usage

Specify a file:

json2yaml ./example.json > ./example.yml

yaml2json ./example.yml | json2yaml > ./example.yml

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);
}());

Example

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"

Note: In fact, both of those Object Notations qualify as YAML because JSON technically is a proper subset of YAML. That is to say that all proper YAML parsers parse proper JSON.

YAML can use either whitespace and dashes or brackets and commas.

For human readability, the whitespace-based YAML is preferrable. For compression and computer readability, the JSON syntax of YAML is preferrable.
