Yes, there is a way to force text in a cell to overlap the cells to its left and right. Here's how you can do it:

1. Select the cell with the text you want to overlap.
2. Click on the "Home" tab in the Excel ribbon.
3. Click on the "Alignment" group.
4. Click on the "Wrap Text" button. This will allow the text to wrap within the cell.
5. Double-click on the cell to enter edit mode.
6. Place your cursor where you want the text to overlap the adjacent cells.
7. Hold down the "Alt" key on your keyboard and type
   Formula:

   010 

   on the numeric keypad. This will insert a line break character.
8. Repeat step 6 and 7 for any other places where you want the text to overlap.

By inserting line breaks, you can force the text to overlap the adjacent cells without changing the size of the cells or the text. You can also adjust the font size or cell width to fine-tune the appearance of the text.
