Frequently Asked Questions

Why does a white rectangle appear in Excel for Mac?

This is a known graphical rendering bug affecting specific builds of Excel (like 16.69.1) on macOS running Apple Silicon. It is typically triggered by intensive UI actions, such as applying filters to datasets with tens of thousands of rows.

Does the white rectangle mean my spreadsheet data is lost?

No. The issue is strictly a visual display glitch. All your entered data, formulas, and formatting remain completely intact underneath the white rectangle.

Will reopening the workbook permanently fix the issue?

Saving and reopening the workbook will only temporarily remove the white rectangle. The graphical glitch may reappear if you perform the same intensive filtering actions again.

How can I safely share my workbook with Microsoft Support for troubleshooting?

Before submitting your workbook, create a duplicate file. Replace all sensitive client information, addresses, and financial figures with generic dummy data while keeping the exact row count, formulas, and table structures intact.
