Frequently Asked Questions

What does the #CONNECT! error mean in Excel?

The #CONNECT! error occurs when Excel cannot establish a connection to an external service to retrieve data. This typically happens when using linked data types (like Stocks or Geography) on unsupported platforms or during network connectivity issues.

Can I use linked data types on Excel for iPad?

Linked data types and their refresh capabilities have significant limitations on Excel for iPad and iPhone. While you might be able to view previously fetched static data, refreshing or adding new linked data generally requires the desktop version of Excel.

Is there a workaround for the STOCKHISTORY error on iOS?

The most reliable workaround is to open and refresh the spreadsheet using Excel on a Windows or Mac computer. Once the stock data is refreshed and the file is saved, you can view the updated static values on your iPhone or iPad.

Does an active Microsoft 365 subscription guarantee all features on mobile?

No. Although a Microsoft 365 subscription unlocks premium features in mobile apps, certain advanced functions and external data connections remain exclusive to the desktop versions of Excel due to mobile operating system constraints.
