title: Magento Magmi column mapper
body: <p>I am using Magmi to import products in Magento DB. I am trying to map columns but I don't have  to map all columns because they have got right name. But only few columns needs to map but I couldn't figure it out, how can I do this. </p>
  
  <p>Should I map all columns available in csv into the mapper ?</p>
  
  <p>What the format mapped column we should put in to the column mapper? Say I have sku_name,category_name,product_type. How this s should be mapped ?</p>
  
  <p>sku_name:sku,category_name:categories,product_type:type.</p>
  
  <p>Is this right format?</p>
  
  <p>Thanks</p>
