Spreadsheet.com supports attachment file imports from Dropbox and other services.
With the Attachment data type, files can live in cells just like other data. And with attachment uploads, you can keep your team's files in Dropbox and attach them into Spreadsheet.com as needed.
How to Link Your Dropbox account
After you have set a cell, range of cells, or column to the Attachment data type, you can then link your Dropbox account to Spreadsheet.com. Linking your Dropbox account allows you to navigate your Dropbox files and chose ones to upload.
To link your account, choose to add an attachment by clicking on the Add attachment button in an attachment cell.
From the add attachment window, select Dropbox from the list of services, and follow the instructions to sign into and link your Dropbox account. Linking Dropbox may open another window in your browser.
How to Upload Attachments from Dropbox
After you have set a cell, range of cells, or column to the Attachment data type and linked your Dropbox account, you can then browse your Dropbox account and chose files to upload.
To link your account, choose to add an attachment by clicking on the Add attachment button in an attachment cell and select Dropbox from the Add attachment dialog. From here, you will open your linked Dropbox account, where you can browse, search, and select files to upload.
Select your desired file or files, chose to Upload the file or files, wait until the file has Completed uploading, and then close the import window. Your selected file will now appear in your attachment cell.
