#### src
> The _src_ can be either the location of a file (_./content/file.docx_) or a string of textual input ("_# Hello, Bananas_").

Converting a word.docx file to a markdown.md

`js
// In EcmaScript 5...

var nodePandoc = require('node-pandoc-promise');
var src, args;

src = './word.docx';

// Arguments can be either a single string:
args = '-f docx -t markdown -o ./markdown.md';
// Or in an array of strings -- careful no spaces are present:
args = ['-f','docx','-t','markdown','-o','markdown.md'];


// Call pandoc
nodePandoc(src, args)
.then(res=>{
console.log(res);
}).catch(err=>{
console.error('Oh No: ',err);
});
`
`js
// In ES-6 (ES-2015)
import nodePandoc from 'node-pandoc-promise'

let src = './word.docx';

// Arguments can be either a single String or in an Array
let args = '-f docx -t markdown -o ./markdown.md';


// Call pandoc
await nodePandoc(src, args);
`

Converting a word.docx file and returning HTML.

`js
var pandoc = require('node-pandoc-promise'),
src = './word.docx',
// Arguments in either a single String or as an Array:
args = '-f docx -t html5';


// Call pandoc
await pandoc(src, args);
`

This also works the other way ’round; converting a bit of HTML and saving it as word.docx

`js
var pandoc = require('node-pandoc-promise'),
src = '

Hello

It’s bananas

',
// Arguments in either a single String or as an Array:
args = '-f html -t docx -o word.docx';


// Call pandoc
await pandoc(src, args);
`

Or give-a-string/get-a-string: Markdown -> HTML

`js
var pandoc = require('node-pandoc-promise'),
src = '# Hello \n\nIt\'s bananas',
// Arguments in either a single String or as an Array:
args = '-f markdown -t html';


// Call pandoc
await pandoc(src, args);
`

...and in reverse: HTML -> Markdown

`js
var pandoc = require('node-pandoc-promise'),
src = '

Hello

It’s bananas

',
// Arguments in either a single String or as an Array:
args = '-f html -t markdown --atx-headers';

// NOTE: The --atx-headers flag set above will produce

s as:
// # Hello
//
// ...while omitting --atx-headers flat will result in this style:
// Hello
// =====


// Call pandoc
await pandoc(src, args);
`

One more thing...

It does URLs too.

`js
var pandoc = require('node-pandoc-promise'),
src = 'https://www.npmjs.com/package/node-pandoc-promise',
// Arguments in either a single String or as an Array:
args = '-f html -t docx -o node-pandoc-promise.docx';


// Call pandoc
await pandoc(src, args);
