To unhide all rows in Excel, the most efficient method is:
- Select the entire worksheet by clicking the "Select All" button (the small triangle at the top-left corner between the row and column headers) or pressing Ctrl + A (press twice if needed to select the whole sheet).
- Then, press the keyboard shortcut Ctrl + Shift + 9. This will immediately unhide all the hidden rows in the sheet.
Alternatively, after selecting all rows, you can right-click anywhere on the row numbers and choose "Unhide," or go to the Home tab, click Format in the Cells group, go to Hide & Unhide, and click "Unhide Rows." These methods also unhide all rows instantly. If rows are hidden due to filters, you need to clear the filters from the Data tab to make those rows visible again. This approach works efficiently for unhiding all rows in Excel at once.
