File size limits for workbooks in SharePoint Online

Applies to: Excel for the web, SharePoint Online.

SharePoint Online has some file size limits for workbooks. Once you upload an Excel for the web workbook to a SharePoint document library that’s too huge, it will either not open in a browser window, or let you edit or refresh data in the browser. To avoid occupying too much disc or memory space, Microsoft 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 is determined bt multiple factors, such as how big a workbook is in file size, what your Microsoft 365 subscription includes, and where the workbook resides.

What are the current file size limits for workbooks?

Your file size limits are influenced by your particular Microsoft 365 subscription.

If your Microsoft 365 subscription includes…And the workbook is stored here…Then these file size limits apply to workbooks in a browser window

Outlook Web AppAttached to an e-mail message0-10 MBIf you’re trying to open a workbook that is attached to an email message in Outlook Web App, a smaller file size limits applies. In this case, the workbook must be smaller than 10 MB to open in a browser window.

If you are using Excel for the web and Power BI, different file size limits apply. For more information, see Data storage in Power BI and Reduce the size of a workbook for Power BI.

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

If a workbook exceeds the file size limit that’s allocated for your Microsoft 365 subscription, you won’t be able to view it in a browser window. However, there are some things you can try:

  • If you have Excel installed on your device, you can download the workbook and then open it in Excel.
  • If you have edit permissions to the workbook, you can try to reduce the workbook’s file size.
