Migration Assessment Scan: Large Excel Files
Learn how to mitigate issues with large Excel files during migration.
Overview
The maximum limit for opening XLSX files in the browser is 10 MB in the target environment. This setting is configurable in the source environment that may result in a change in behavior for your users. If you attempt to open a file larger than 10 MB from a SharePoint site, it prompts you to open the file in the Excel client application.
Data Migration
XLSX files are migrated.
Important
Any site that is configured as "No Access" (locked), in SharePoint will be skipped. To see a list of locked site collections see the Locked Sites scan output.
Preparing for Migration
Notify users of the expected behavior.
Post Migration
Attempting to open an XLSX file larger than 10 MB will prompt you to open the file in the Excel client. You'll be prompted with a dialog.
