One option could be to push that data off to Google Sheets or another similar service using the Zapier add-on.
We also offer a couple products over at ForGravity that could help you do something like this with slightly different approaches.
Entry Automation would allow you to set up your entry data to export automatically on a schedule in either CSV, Excel, PDF, or JSON format. These export files can be emailed to any email addresses of your choosing automatically, and with our Agency license tier can be pushed off elsewhere using our Dropbox, Amazon S3, or FTP extensions.
Advanced Permissions would allow you to have your users access your form entry data directly in the WordPress admin, but keep their access limited to just the forms, and the sub-components of those forms, they need access to.
By default with Gravity Forms, only administrator role users get access to the Gravity Forms pages in the WordPress admin, even if you grant those capabilities needed to other user roles using a role editor plugin, those capabilities are still applied globally across the entire Gravity Forms install, so it may give the user access to forms you don’t want them to have access to. Advanced Permissions allows you to apply those same Gravity Forms capabilities to any non-administrator user or role, but just for the forms you want the users to have access to, they won’t see or have access to others.
