Categorise our products according to Google merchant centre

I have a list of about 1,100 products which I need to have matched up to the relevant category. I will supply a spreadsheet with our products listed in a column. I require the relevant Google category to be entered in the next column. These are the google categories - http://support.google.com/merchants/bin/answer.py?hl=en&answer=160081. The products are available to view on our site at http://tabswear.co.uk/all-products.
