- Product
- Excel for the web (Excel Online)
- Device & OS
- not provided
- Scenario
- Filtering data in a frequently updated online workbook.
- Observed behavior
- The filter drop-down menus stop responding when clicked if the filter range is positioned below frozen rows, despite working perfectly in the desktop application.
Verify that your data doesn't contain grouped sheets or active background macros that might interfere with Excel for the web functionalities.
Unfreeze Panes Above the Filter Range
This is the most effective fix, as Excel for the web currently experiences a known bug when filters are placed below frozen rows.
When your data headers and filters are located in the second row (or below) and the rows above them are frozen, the web version of Excel struggles to render the drop-down action. Unfreezing the panes resolves the conflict immediately.
In your open workbook in Excel for the web, navigate to the top ribbon and click on the 'View' tab.
Click on 'Freeze Panes' and select 'Unfreeze Panes' from the drop-down menu.
Click on your data filter drop-down again to confirm that it is now responding correctly.

Move Headers and Recreate the Filter in Row 1
If you absolutely must use frozen panes, moving your headers to the very first row bypasses the bug in Excel Online.

Frequently Asked Questions
Why do Excel Online filters stop working when rows are frozen?
This is a known bug in Excel for the web. When a filter range is placed in the second row or below, and the rows above it are frozen, the web interface fails to register clicks on the drop-down arrows.
Will my filters work if I open the file in the Excel desktop app?
Yes, the desktop version of Excel does not suffer from this specific frozen pane filter bug. The drop-downs will function normally, although switching to desktop might not be practical for frequently updated collaborative files.
How can I freeze rows without breaking the filter in Excel Online?
To avoid breaking the filter, ensure that your data headers and filters are located exactly in Row 1. You can then safely freeze Row 1 without causing the drop-downs to freeze or become unresponsive.
