If this is a one-time usage spreadsheet, you can use it and delete it. If you plan to use it again or would like to share it with others, you should upload your final draft of the spreadsheet back up into the SSRS environment. To do this, simply go into the proper SSRS folder and choose the Upload option. SSRS is a secure place to store data and spreadsheets, and it is also backed up every night to a server. Please give your spreadsheet a name that will tell people about it's purpose, and also consider documenting right inside of your spreadsheet.
