Export the contacts (Google Contacts) as a CSV file (either one). (Make sure that all your contacts are Google contacts first, of course - just in case you entered some as Phone, Device or SIM contacts.) That gives you a file you can open in Excel (or OpenOffice or Libre Office or any spreadsheet program). You don't even need your phone - you can do it all with the laptop - including creating the file at Google Contacts and downloading it.
