Upload an Attachment

You can attach almost any type of file to a sheet, row, discussion, or workspace. You can attach files from your computer or files stored in supported third-party cloud storage services. This article discusses attaching files from your computer.

For information about attaching files from third-party cloud storage services, see Attachments from Google Drive, OneDrive, Box, Dropbox, Evernote, Egnyte & URL.

TIP: If you commonly receive attachments in email, note that you can capture those in a sheet via the Smartsheet for Gmail add-on or the Smartsheet for Outlook add-in. For more information, see these articles:

• Smartsheet for Gmail Add-on
• Smartsheet for Outlook Add-in

Attachments and Sharing Permissions

Anyone who has been shared the sheet or workspace (Viewer, Editor, Admin) can view and download the attachments. Everyone except Viewers will be able to add, edit, or delete attachments.

Upload an Attachment from Your Computer

The steps you use to attach a file will depend on the type of Smartsheet item you're working with. Follow the steps for the item type you're using to open the Attachment Summary form.

NOTE: You won't be able to attach files at all if you're using an Enterprise account and your SysAdmin has disabled file attachment options. For more information, see "File Attachment Options" in the Global Account Settings article.

Supported File Formats and Sizes

The vast majority of file types are supported for uploading, including image, PDF, Microsoft Word, Microsoft Excel, and Microsoft PowerPoint files. For security reasons we don’t allow you to upload file types that could pose a risk when downloaded, such as .exe, .cmd, .js, .jsp, and .bat file types.

The maximum size of a file that can be uploaded to a sheet owned by a licensed (paid) user is 250 MB per file. For a sheet owned by a trial account, this maximum is 30 MB per file. You can upload 100 files at a time. While there isn't a limit to the total number of attachments allowed on a row or sheet, you are bound by the amount of storage space included in the sheet owner's subscription.

An account SysAdmin can review the storage space allowed on your plan and the amount you're currently using by clicking Account > Account Admin.

NOTE: A browser that supports HTML 5 is required to upload files larger than 30 MB. For more information about supported browser types and versions, please see System Requirements for Using Smartsheet.
