Hi Renee,
We do not store your excel files that you use to import sessions, but within your event, you can always go to Agenda > Session List > Check off all of your sessions > Actions > Export Sessions and export all of the current session details in the same format that would be used to import them back into the system. So you can export, easily review and make any additional changes and re-import that same file back in if needed.
If you just need to look at a sample session import template, that can be done within Agenda > Session List >Import Sessions and then click on "Download a file containing the default column names that will be mapped to Cvent fields."
