title: Cut and paste data range to bottom of another sheet
body: <p>I'm new to google app script and not sure how to solve this issue.</p>
  
  <p>I have two sheets, "Main" and "Extract". Throughout the day, data is pasted into the "Extract" sheet, cleaned up (script removes certain columns and removes rows where a value in column A also exist in column A of the "Main" sheet), and then added to the "Main" sheet, which contains all of the cleaned up extracts pulled throughout the day. </p>
  
  <p>I am trying to write a script that will take all of the cleaned up data in the "Extract" sheet and cut and paste it beneath the last row with data in the "Main" sheet. </p>
  
  <p>Once cleaned up the "Extract" sheet always has 8 columns (A-H), but the amount of rows varys each time. I do not need the header or column 8 (H) pasted to the "Main" sheet, only A2:G (stopping at the last row with data).  </p>
  
  <p>So far this is all I have been able to come up with (it is likely very wrong)</p>
  
  <pre><code>var data = sheet.getDataRange().getValues()
  .offset(0, 0, 1);
  </code></pre>
