<p>You can do this by grabbing the keys of every object, sorting them, and then mapping them to an array.</p>

<p>Step by step:</p>

<p>Here's a an approach using <a href="https://lodash.com/docs/4.17.4#map" rel="nofollow noreferrer">lodash#map</a> with a <a href="https://lodash.com/docs/4.17.4#unary" rel="nofollow noreferrer">lodash#unary</a> wrapped <code>lodash#map</code> iteratee.</p>

<pre><code>var result = _.map(data, _.unary(_.map));
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="true" data-console="true" data-babel="false">
<div class="snippet-code snippet-currently-hidden">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var data = [{a:'one',aa:'eleven'},{a:'two',aa:'twelve'},{a:'three',aa:'thirteen'}];

var result = _.map(data, _.unary(_.map));

console.log(result);</code></pre>
<pre class="snippet-code-css lang-css prettyprint-override"><code>body &gt; div { min-height: 100%; top: 0; }</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.js"&gt;&lt;/script&gt;</code></pre>
</div>
</div>
</p>

<p><strong>Update</strong>
To preserve key orders, you may replace the <code>lodash#map</code> iteratee into <a href="https://lodash.com/docs/4.17.4#at" rel="nofollow noreferrer">lodash#at</a> that is <a href="https://lodash.com/docs/4.17.4#partialRight" rel="nofollow noreferrer">partially</a> applied with the <code>keys</code> that defines the order of the values.</p>

<pre><code>var keys = ['aa', 'a'];
var result = _.map(data, _.unary(_.partialRight(_.at, keys)));
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="true" data-console="true" data-babel="false">
<div class="snippet-code snippet-currently-hidden">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var data = [{a:'one',aa:'eleven'},{a:'two',aa:'twelve'},{a:'three',aa:'thirteen'}];

var keys = ['aa', 'a'];
var result = _.map(data, _.unary(_.partialRight(_.at, keys)));

console.log(result);</code></pre>
<pre class="snippet-code-css lang-css prettyprint-override"><code>body &gt; div { min-height: 100%; top: 0; }</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.js"&gt;&lt;/script&gt;</code></pre>
</div>
</div>
</p>

<p>An es6 alternative of the solution above would be:</p>

<pre><code>var keys = ['aa', 'a'];
var result = _.map(data, v =&gt; _.at(v, keys));
</code></pre>

<p><div class="snippet" data-lang="js" data-hide="true" data-console="true" data-babel="true">

var keys = ['aa', 'a'];

<p>I have an arrays of objects, lets say </p>

<pre><code>[{a:'one',aa:'eleven'},{a:'two',aa:'twelve'},{a:'three',aa:'thirteen'}]
</code></pre>

<p>I want to convert the objects into arrays, something like this</p>

<pre><code>[['one','eleven'], ['two','twelve'],['three','thirteen']]
</code></pre>

<p>as property name should map to a given correct index in the array</p>

<p>Is this possible using Lodash or javascript?</p>
