How to use

  1. 1 Paste CSV with headers in the first row and labels in the first column.
  2. 2 Toggle stacked or horizontal to switch layout. Multiple data columns become side-by-side or stacked groups.
  3. 3 Download the rendered chart as PNG for slides or reports.

Why use this tool

  • Stacked and horizontal toggles — one tool covers grouped, stacked and side-bar layouts.
  • Chart.js loaded lazily — fast first paint, no upload.
  • Multi-series ready — every numeric column in your CSV becomes a separate bar series.
  • Quoted CSV cells supported, including commas and newlines inside fields.
