Locate hidden cells on a worksheet
When you want to unhide cells in hidden rows or columns in a worksheet, it can be hard to locate them. By finding and selecting all visible cells in the worksheet, you can more easily detect the hidden rows and columns.
For more information about displaying hidden rows or columns, see Hide or display rows and columns.
Click the worksheet that contains the hidden rows and columns that you want to locate.
On the Home tab, in the Editing group, click Find & Select.
Click Go To Special.
Under Select, click Visible cells only, and then click OK.
All visible cells are selected and the borders of rows and columns that are adjacent to hidden rows and columns are marked with a white border.
