Upload Excel or CSV data and describe the hierarchy and measure you want to compare. ExcelDashboard AI can aggregate parent and child categories, size each rectangle by value, add a defensible color measure, and produce an editable treemap with a concise explanation.

Why it matters
Comparing the relative size of many categories inside a hierarchy, such as product revenue within departments, portfolio value within asset classes, or cost within business units.
Avoid a treemap when exact comparisons between similarly sized values matter, when values can be negative, when there is no meaningful hierarchy, or when labels become unreadable across too many tiny categories.
Capabilities
The AI can aggregate repeated hierarchy paths, preserve parent-child relationships, size rectangles by a non-negative measure, group very small categories, and use color for a distinct metric such as growth or margin rather than decoration.
Provide one or more categorical hierarchy fields and a non-negative numeric size measure. Add a separate color measure only when its meaning and scale are clear, and document aggregation, missing values, and the total denominator.
Specify sums, averages, counts, rates, time intervals, and filters so the values behind the visual remain inspectable.
Refine titles, labels, colors, annotations, and chart type, then reuse the visual in a dashboard or report.
How it works
Start with Excel, CSV, or a table and confirm that headers, numeric values, categories, and dates were interpreted correctly.
Provide one or more categorical hierarchy fields and a non-negative numeric size measure. Add a separate color measure only when its meaning and scale are clear, and document aggregation, missing values, and the total denominator. Explain the audience and the question the chart should answer.
Check the values, labels, scale, and filters. Avoid a treemap when exact comparisons between similarly sized values matter, when values can be negative, when there is no meaningful hierarchy, or when labels become unreadable across too many tiny categories.
Common use cases
Show revenue, units, or margin by department, category, and product while keeping the full portfolio visible.
Compare spending across divisions, departments, programs, and accounts in one hierarchical view.
Explore account value, market size, or demand by region, segment, and customer group.

Yes. Review the data mapping first, then adjust the chart type, titles, labels, colors, annotations, and surrounding report content.
