Parse Data

I have a spreadsheet that lists over 200 business names, addresses, phone numbers, and email addresses. Instead of the data being separated to columns, it is all in one column. Every 12th line starts a new set of data. All the data is in the same order(i.e. Business name, owner, street address, city, state, zip, phone, fax, url, email address, blank line) How can I parse eleven consecutive lines to columns, then the next 11 lines to matching columns, and so on quickly?
