In addition to PDF, you can now choose one of the following new attachment types for your subscription(s) –
PowerPoint presentation (PPTX)
Excel Workbook (XLSX)
Word Document (DOCX)
CSV file
XML
To choose one of these new attachment types, head to one of your paginated reports in Power BI and click on the “Subscribe” button in the toolbar
You’ll now see a new dropdown menu in your subscription pane that allows you to select an attachment type format when you’re creating or editing your paginated report subscription.
Your subscription will now include the attachment type you’ve selected each time it’s delivered to your inbox.
In addition to these new attachment types, we’ve also raised the attachment file size limit to 25 MB for paginated reports to provide new options for popular customer scenarios like scheduled large data exports.
We’d love to hear your feedback in the comments below about your experiences with Paginated Reports. Stay tuned for another announcement soon around new features for both paginated reports subscriptions and a BIG new update for Power BI Report Builder.
