Compare business performance
Scan regions, products, teams, or periods to find clusters of high and low performance.
Use Heatmap Generator to turn a labeled matrix into a readable color map. Compare exact values across rows and columns, switch color scales, and export SVG or PNG directly in your browser.
Start from an accurate matrix example, then replace its labels and values with your own data.
Use a heatmap when the relationship between two categorical dimensions matters as much as each exact value.
Scan regions, products, teams, or periods to find clusters of high and low performance.
Map activity by hour, weekday, cohort, channel, or another repeated dimension.
Visualize relationships among research variables with positive and negative values around zero.
Compare ratings across questions and groups while retaining the underlying scores.
See performance across students, classes, assessments, or curriculum areas in one view.
Visualize expression values, experimental measurements, or coded observations across samples.
Keep matrix input, color scale, exact values, preview, and export in one focused workspace.
Copy rows with the header row and row labels intact.
Upload CSV or XLSX files, or paste comma-, tab-, or semicolon-separated data from Excel, Google Sheets, CSV, or TSV.
Minimum and maximum values define a consistent scale across the full matrix.
Show each numeric cell on top of its color whenever readers need precise lookup as well as pattern recognition.
Use sequential colors for magnitude, diverging colors around a midpoint, or perceptually even Viridis.
Save an editable vector for reports or a ready-to-share bitmap for documents and slides.
Move from raw matrix to presentation-ready visual without rebuilding the data in a full design application.
Every cell color is calculated deterministically from the visible numeric data.
The preview updates as soon as you paste or change the matrix.
The browser-based chart renderer does not need to send the matrix to an image model.
SVG export keeps text, cells, and legend sharp at document, slide, or poster size.
Labels, values, contrast-aware text, and a shared legend keep the visual interpretable.
Switch palettes without re-entering the data or changing the matrix structure.
Paste a labeled matrix, choose a meaningful color scale, then export the heatmap you reviewed.
Step 1
Include column labels in the first row, row labels in the first column, and numeric values in the remaining cells.
Step 2
Use a sequential, diverging, or Viridis scale and decide whether exact values should appear in every cell.
Step 3
Check the minimum, maximum, missing cells, labels, and legend before exporting SVG or PNG.

Every cell uses one shared scale, so colors remain comparable across the entire matrix.
