Heatmap Generator

Create heatmaps from row-column-value data matrices.

Data & Statistics

Heatmap Generator transforms row-column-value data into an intensity matrix so patterns and hotspots are visible immediately. It is useful for regional performance grids, cohort analysis, staffing utilization, and product-category comparisons where tabular values are hard to scan quickly. The tool ingests `Row, Column, Value` lines, computes min/max, and colors cells by normalized intensity. Missing combinations remain visible so data gaps are easy to detect. Use it to compare many combinations at once and identify where values are unusually high or low.

Input guidance

Provide data as `Row, Column, Value` lines for each matrix cell you want to populate.

How to use this tool

  1. Provide data as `Row, Column, Value` lines for each matrix cell you want to populate.
  2. Click `Generate Heatmap` to build the intensity table and value range summary.
  3. Use darkest/lightest cells to identify hotspots, weak areas, and missing combinations.

Heatmap Inputs

Use Row, Column, Value on each line.
