title: Mixed Service Codes/Descriptions database
body: <p>I am facing an issue regarding a significantly large database that I have to reorganize. There are two columns, one consists of the Service Code of an item and next is a column containing the Description of the relevant item. Below is an example:</p>
  
  <pre><code>TSB Trim Booklet
  LMN Loading Manual
  GLM Grain Loading Manual
  </code></pre>
  
  <p>etc.</p>
  
  <p>There are a total of 170 different items.</p>
  
  <p>The problem is this: On a different Excel file, there is a column containing (mixed around 16,000 times) only the Descriptions of the items without the 3-letter Service Code.  </p>
  
  <p>How can I link them quickly?</p>
