How do I undo my last action in Excel using the CTRL + Z shortcut?

To undo the last action in Microsoft Excel, you can use the keyboard shortcut CTRL + Z. This will undo the last action you performed, whether it was typing, formatting, or editing data in a cell. If you want to undo multiple actions, you can continue to press CTRL + Z until you have undone all the actions you want to undo.

Another way to undo an action is to click on the 'Undo' button on the Quick Access Toolbar, which is located above the ribbon. The 'Undo' button has an arrow pointing to the left and the word 'Undo' next to it. Clicking on this button will also undo the last action you performed in Excel.
