The sheet Owner, Admins, and Editors can add, version, or delete attachments. Anyone with access to the sheet can view and download attachments. Attachments can be sent in an email to anyone with a valid email address.

System Admins for Enterprise accounts can disable any file attachment options. For more information, see Manage Global Account Settings.

You can attach almost any type of file to a sheet, row, or comment. This is useful when you want to relate files to items that you're keeping track of in Smartsheet.

You can attach files stored on your computer or files stored in supported third-party cloud storage services. This article discusses attaching files from your computer. For information on how to attach files from supported third-party services, see Attach a File From an Online Resource.
