What type of cells summarize contributing values?

Rollup cells are designed to summarize contributing values by aggregating data from other cells. They typically perform calculations such as sums, averages, or other statistical analysis based on the data inputs from the referenced cells. This makes them essential in scenarios where you want to simplify reports or financial statements by providing a consolidated view of multiple data points in a single location.

This type of cell enables a streamlined approach to managing large datasets by automatically updating whenever the underlying values change, ensuring that summaries remain accurate without requiring manual recalculations. This is particularly useful in financial planning and analysis, where maintaining accurate totals and summaries is essential for decision-making.

In contrast, read-only cells allow users to view data without the ability to modify it; even adjustment cells might handle specific corrective entries but do not inherently summarize values; and proportional cells involve distributing values in proportion to assigned weights, rather than summarizing contributions. Thus, rollup cells are the appropriate choice when the objective is to consolidate and summarize data effectively.
