Importrange from multiple google spread sheets
<p>I know how to import data from ONE spread sheet to another:</p>

<pre><code>=IMPORTRANGE(spreadsheet_key, range_string)
</code></pre>

<p>Source: <a href="https://support.google.com/docs/answer/3093340?hl=en&amp;ref_topic=3105411" rel="nofollow">https://support.google.com/docs/answer/3093340?hl=en&amp;ref_topic=3105411</a></p>

<p>But how do I import MULTIPLE spread sheets into one "master spread sheet"?</p>

<p>Something like this:</p>

<pre><code>=IMPORTRANGE(spreadsheet_key, range_string),IMPORTRANGE(spreadsheet_key, range_string),IMPORTRANGE(spreadsheet_key, range_string)
</code></pre>

<p>All spread sheets have the exact same structure.</p>

<p>I want all data in the same sheet in the same columns.</p>

<p>Preferebly I would like to import all spread sheets automaticly that are placed in one folder into the "master spread sheat".</p>
