If you want to continue using the same spreadsheet, just copy it to a thumb drive or CD, and place it on the new PC after you have installed Excel. If you want a new version of the sheet, the instructions to transfer the data to the new sheet are on the account info tab in MyCostPro.
If you want your boss to use your token, you can just let him use the sheet. If you want him to be able to see your current data without being able to connect to eBay, you can remove your download key from the account info section of MyCostPro, and save as a different file. If you give him this new file, it should contain all of your data, but he will not be able to retrieve more or update your listings.
