title: insert data to bigquery from gsheet
body: <p>I would like to upload data to a table in bigquery from gsheet, I mean I want to upload the data with code and not with add on, because it will be scheduled later on.
  Is there any code example that I can use for that for both ways (append and truncate)?
  I have a 2 columns data that I want to load.
  The columns are:</p>
  
  <pre><code>name    lastName    
  josh    big
  john    troble
  </code></pre>
  
  <p>May be some code using the following function </p>
  
  <pre><code>BigQuery.Jobs.insert(resource, projectId)
  </code></pre>
