title: How to convert multiple column from text to date?
body: <p>In my excel file, there are hundred columns. I want to convert some columns (eg. Column A, C,F, G..) from text to date. It really take time if manually change each column one column by one.
  How can I do it ? By using VBA ?</p>
  
  <p>The original text column format just like '31-Dec-2011 00:00:00'. I want to convert to 'dd/mm/yyyy' 31/12/2011</p>
  
  <p>Thanks</p>
