To merge two cells without deleting data from the cell, you can follow these steps:

1. Select the two cells that you want to merge.
2. Right-click on the selected cells and choose "Format Cells" from the drop-down menu.
3. In the Format Cells dialog box, click on the "Alignment" tab.
4. Under the "Horizontal" section, select "Center Across Selection" from the drop-down menu.
5. Click "OK" to close the dialog box.

This will merge the two cells into one without deleting any data. The data from both cells will be displayed in the merged cell, with the data from the left cell appearing first and the data from the right cell appearing second.

Alternatively, you can also use the symbol to combine the data from two cells into one cell. Here's how:

1. Select the cell where you want to combine the data.
2. Type
   Code:

   ="

   followed by the cell reference of the first cell you want to combine.
3. Type
   Code:

   &

   (without the quotes).
4. Type the cell reference of the second cell you want to combine.
5. Press Enter.

This will combine the data from the two cells into one cell, without deleting any data.
