Final answer:
The Format Painter is the tool used to copy formatting from one object and apply it to another within Microsoft Office applications.
Step-by-step explanation:
The tool in question for copying the attributes of an object and applying them to another object is known as Format Painter. This tool is widely used in various Microsoft Office applications such as Word, Excel, and PowerPoint. When you select an object with the Format Painter, it "picks up" the formatting attributes like font size, color, borders, and others from that object. You can then apply these attributes to another object by clicking on it, which makes the second object match the formatting of the first object.
