What is the purpose of adding secondary filters to a worksheet?

Adding secondary filters to a worksheet primarily serves the purpose of displaying more focused data for users. This allows for a refined view of the dataset that aligns with specific criteria or inquiries, enabling users to drill down into the information that is most relevant to them without being overwhelmed by extraneous data.

By implementing secondary filters, users can isolate particular subsets of their data, making it easier to analyze trends, derive insights, or assess performance in targeted areas. This customization is essential in environments where data sets are large and complex, as it enhances the utility of the worksheet by ensuring that users only see data that meets their specific conditions or interests.

The other options, while they may have merit in certain contexts, do not directly relate to the primary intent of secondary filters. Summarizing data quickly and eliminating duplicates are also valuable functions, but they address different aspects of data management rather than the focused data presentation that secondary filters provide. Enhancing visual representation relates more to formatting and design choices rather than filtering data itself.
