Smartsheet allows you to attach and manage files directly in your sheet so you can access all of your work in one place. Files can be attached from your desktop and the most popular cloud storage providers.


Learn how to attach files to a sheet and keep all your key project information in one place, so your team can access the latest version at any time. Attach files from other services or upload files from your computer to keep large attachments out of your email inbox.

Follow the step-by-step instructions to add attachments to your sheet.

Attach Files Stored on Your Computer to a Sheet

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.

Who can use this capability

Permission requirements icon Owners, Admins, and Editors on a sheet can add, version, or delete attachments. Anyone with access to the sheet can view and download attachments. You can send an attachment in an email to anyone with a valid email address.
Plan availability icon All plan types. System Admins for Enterprise and Premier accounts can disable any file attachment options. (See Manage Global Account Settings.)

How you attach files depends on where you'd like them to be connected. You can attach files on the sheet level, or relate files more directly to a line item or comment by attaching them there.
