What is the advantage of using variables in filter expressions?

Using variables in filter expressions provides significant advantages, particularly in simplifying the process of data analysis and manipulation. The correct choice reflects that they help in simplifying complex data manipulations. By utilizing variables, users can define specific conditions that need to be met, which can make it easier to manage and analyze data sets with multiple criteria.

Variables allow users to create dynamic filters that automatically adjust based on user-defined values or external inputs. This means that instead of rewriting a filter expression every time conditions change, users can simply update the variable, enhancing efficiency and reducing the potential for error. Overall, effective use of variables leads to clearer and more maintainable code or expressions, making it easier for users to understand the underlying logic and improve their workflow.

Other choices mention ensuring values fit within preset ranges, merging records, or grouping records from different worksheets. While these are relevant in the context of data manipulation, they do not accurately capture the primary benefit of using variables in filter expressions, which is centered around simplifying the overall complexity of data management tasks.
