How do I merge cells in Excel using the ALT + H + M + C shortcut?

To merge cells in Excel using the ALT + H + M + C shortcut, you first need to select the cells you want to merge. Then, press and release the ALT key, followed by H, M, and C keys one after another, while holding down the ALT key throughout.

Once you press the final C key, the selected cells will be merged into a single cell, and the content in the upper-left cell of the selection will be preserved. Any other content in the adjacent cells will be discarded.

Alternatively, you can also use the Merge & Center button in the Alignment section of the Home tab, or select the Merge Cells option from the right-click context menu.
