    <p>My end goal is to write a simple program that downloads one specific Google spreadsheet at the end of each week to my local hard drive. The file will be edited on a week to week basis by other people, and I will constantly need to download the updated version to pull out data and pass to a bash script that I have written. I am now doing this manually, but if I can pull down the spreadsheet in a csv format, can automate the entire process.</p> <p>I am slightly confused by Google's Documentation. I have copied their example method <code>downloadFile</code>, but am still unclear about the exact parameters that are being passed, and the <code>InputStream</code> return.</p> <p>If I were to add a main method to call the <code>downloadFile</code> method, what would be example parameters that I pass. </p> <p>Then, can I use the <code>InputPut</code> stream it returns to save the file is csv format? </p> <p>Also, is this the only method I need or do is there more to it? </p> <p><code>downloadFile</code> method is defined here (left out the import statements): </p> <pre class="lang-java prettyprint-override"><code>private static InputStream downloadFile (Drive service, File file) { if (file.getDownloadUrl() !=null &amp;&amp; file.getDownloadUrl().length() &gt; 0) { try { HttpResponse resp = service.getRequestFactory().buildGetRequest(new GenericUrl(file.getDownloadUrl())).execute(); return resp.getContent(); } catch (IOException e) { e.printStackTrace(); return null; } } else { return null; } } </code></pre>

    1. COFor the "Drive" parameter, you sure you did not mean "Driver"? I can't find any API on a Drive class.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
