Funnel Chart Generator

Create funnel charts from stage values and inspect conversion drop-off.

Last validated: 2026-02-14

Funnel Chart Generator converts sequential stage values into a visual funnel so you can see where drop-off happens between steps. It is useful for sales pipelines, signup journeys, onboarding flows, and support resolution stages where conversion at each step matters. The tool accepts simple `Stage, Value` rows, scales widths relative to the largest stage, and calculates stage-to-stage conversion percentages automatically. Invalid lines are skipped with clear warnings for fast cleanup. Use it to identify bottlenecks and prioritize improvement efforts in the stages losing the most volume.
