Cross two categorical columns, aggregate a number, and read the pattern by color. Perfect for spotting where values cluster — by region × month, product × channel, anything.

A heatmap turns a cross-tab into color so patterns jump out. Pick the two columns to cross and the number to aggregate. Darker cells mean larger values; empty cells are left blank.
We detect delimiters and column types. Excel files are converted automatically.
Rows × columns, aggregated by sum, average or count. We pre-fill good defaults from your data.
Read the hot and cold cells, hover for exact values, then download the heatmap as SVG or PNG.
A grid of numbers hides the story. The same grid in color tells it instantly.
A perceptually-even color scale maps small-to-large onto light-to-saturated so relative size reads at a glance.
We rank dimensions by total and show the most significant cells, so a wide dataset stays readable.
Color shows the shape; hover any cell for the precise aggregated value.
Download a crisp SVG for decks and docs, or a 2× PNG for quick sharing.
