File size limits for workbooks in SharePoint Online

SharePoint Online has some file size limits for workbooks. When you upload an Excel Online workbook to a SharePoint document library that's too large, it will either not open in a browser window, or let you edit or refresh data in the browser. To keep from consuming too much disk or memory space, Office 365 SharePoint Online puts some file size limits on the files or workbooks you can upload and work with online.

Whether you can view and interact with a workbook in a browser window depends on several factors, such as how big a workbook is in file size, what your Office 365 subscription includes, and where the workbook resides.

What are the current file size limits for workbooks?

Your file size limits are determined by your particular subscription to Office 365. If your subscription includes Power BI for Office 365, then you’ll be able to open, view, and interact with larger workbooks in a browser window than if you just had SharePoint Online.

What happens if the workbook’s file size is too big?
