The tool that stops words in a cell from overflowing into adjacent cells is the "Wrap Text" feature. When you enable Wrap Text on a cell (such as A55), the text will automatically wrap within the cell boundaries, and the row height will adjust to fit the full content, preventing the text from spilling over into the next cell (e.g., B55)

How to apply Wrap Text:

• Select the cell(s) you want to stop from overflowing.
• Go to the Home tab in Excel.
• In the Alignment group, click the Wrap Text button.

This ensures all the text stays contained within the cell, making the spreadsheet look tidy and readable

Additional methods to control overflow:

• Adjust column width : Widen the column so the content fits without wrapping.
• Fill horizontal alignment : In Excel, setting horizontal alignment to "Fill" can truncate text at the cell boundary, but it may repeat text in shorter cells

• Insert a space in adjacent empty cells : Typing a space in neighboring empty cells prevents overflow visually by occupying those cells

• Use formulas like LEFT() : To limit displayed text length within a cell without overflow

Among these, Wrap Text is the most straightforward and commonly used tool to stop words from overflowing into adjacent cells.
