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).
Installation
npm install -g json2yaml
Note: To use npm
and json2yaml
you must have installed NodeJS.
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:
{ "use strict"; var YAML = ymlText ; ymlText = YAML; console;};
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.
