Workbooks are subject to limits on the amount of attachments and images they can contain based on your current Spreadsheet.com plan. The limits are:
| Free | Standard | Premium | Enterprise |
| 100 MB | 2 GB | 50 GB | Unlimited |
Individual attachments are each limited to a maximum file size of 20 MB. Cells can contain an unlimited number of attached files, but the maximum number of files that can be attached at one time is 5.
