Hi,
Thank you for sharing your question. I understand how frustrating it is when your stock data in Excel stops refreshing, and I’m glad you reached out for help.
Often this issue stems from Excel not being able to retrieve data from the online source due to connectivity issues, service outages, or file settings
The first thing to check is your internet connection, ensuring it’s stable and not blocking Excel from reaching Microsoft’s data servers. If connectivity is fine, confirm that your stock values are correctly formatted using Excel’s Stock data type—when a cell has that format, Excel treats it as a linked data type that should auto-refresh.
Next, review your refresh settings: right-click a stock data cell, choose Data Type → Refresh Settings, and ensure that the option is set to Automatically every 5 minutes or On file open, rather than “Manually”. If it's set to manual, you’ll need to refresh manually each time.
I hope this helps.
Best Regards,
Noel
