Free Treemap Maker — Paste Data, Download Instantly
A treemap turns your rows into rectangles — area proportional to value — so a long list of numbers becomes one picture where the biggest contributors are impossible to miss.

Treemaps use the first numeric column only.
No editable .xlsx for Treemap — Excel's standard chart format has no such chart, so there is nothing editable to export. Use Download PNG instead.

Frequently asked questions
When is a treemap better than a pie chart?
With many categories. A pie becomes unreadable past 6 slices; a treemap stays legible with dozens of rectangles.
Which column does the treemap use?
The first numeric column — a note under the chart reminds you if your table has more.
Is it free?
