title: Stripping letter suffix from product identifiers?
body: <p>I have a CSV file with a list of SKU's, each of which is a separate row corresponding to other product attributes like description, color, etc.</p>
  
  <p>I need to import product color swatches for identical item identifiers that have multiple colors. I need to find a common identifier to make as a base for the rest of the colors.</p>
  
  <p>So the data is like:</p>
  
  <p><a href="https://i.stack.imgur.com/Bj20A.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Bj20A.png" alt="enter image description here"></a></p>
  
  <p>I need to cut the letter(s) suffix and paste it to the adjacent column, leaving just the base identifier from which I can remove duplicates and filter the base. The hard part is that each identifier can have different suffix length, so the next item can be <strong>ACC3205A-SET2</strong> -- the only real consistency is that every item has three <em>prefix</em> letters (<strong>ABC)</strong> followed by four adjacent numbers. Everything after that should be removed and pasted to adjacent column. Is this easily doable in VBA?</p>
