title: Delete A1 cell if B1 is empty
body: <p>I need excel formula for office 2007.
  If cell <code>B1</code> is empty then make <code>A1</code> empty by deleting <code>A1</code> cell. I just want to make A1 empty not want to delete entire row.</p>
  
  <p>If <code>B1</code> is not empty, Keep <code>A1</code> values unchanged.</p>
