Final answer:
The Sort dialog box allows up to 64 nested levels of sort criteria, enabling detailed sorting on multiple levels.
Step-by-step explanation:
In the Sort dialog box, you can utilize up to 64 nested levels of sort criteria. This allows you to sort data in a spreadsheet or database on multiple levels, creating a hierarchy of sort conditions. For instance, you could first sort a list of names alphabetically by last name, then by first name, and perhaps even by a third criterion like city or birth date. As you increase the number of nested levels, the data becomes more finely sorted according to the additional criteria.
