Free Heatmap Maker — Paste Data, Download Instantly
A heatmap colors every cell of your table on a scale from light to dark — patterns, peaks and dead zones show up before you read a single number. Every cell of your pasted matrix becomes a tile.
| Month | Product A | Product B |
|---|---|---|
Each cell is one value: categories × series.
No editable .xlsx for Heatmap — Excel's standard chart format has no such chart, so there is nothing editable to export. Use Download PNG instead.
