Funnel chart
Show how a population narrows through sequential stages of a process. Create a private, publication-ready funnel chart directly in your browser without transmitting sensitive rows off-device. Data is processed locally on your hardware with zero server uploads, enabling instant export to SVG, PNG, and Excel data.
Edit the data, then export.
Everything runs in your browser. Your data is not uploaded.
Data
Paste tab-separated data from Excel or edit the cells directly.
Paste or import table data
Paste a header row, or choose a local CSV/TSV file. Files are read in this browser and capped at 500 rows.

SVG, PNG, and Excel exports are generated locally in this browser. PowerPoint export is temporarily unavailable while its dependency path is reviewed for a high-severity image parser advisory.
Multi-Variable Correlation & Flow Mechanics
A funnel chart visualizes how a starting population narrows through sequential, linear stages of a process. It achieves this by displaying progressively smaller, centered horizontal bands, where the width or area of each band represents the remaining volume at that step. This chart is ideal for identifying bottlenecks in user flows, lead generation, or sales pipelines. All your conversion data is processed locally on your device, ensuring complete privacy with no server uploads.
Coordinate & Matrix Data Structure
Format input columns for funnel chart with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.
Sample Observation Matrix
| Stage | Users | Conversion (%) |
Correlation Traps & Analytical Guidelines
- Ensure sufficient visual distinction for funnel chart marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for funnel chart elements.
- Double-check scale boundaries and zero-anchors before exporting funnel chart presentation artwork.
- Data shape
- Ordered stage and numeric value columns
- Exports
- SVG, PNG, and Excel data; PowerPoint export is temporarily unavailable pending dependency review.
How it works
You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.
Frequently asked questions
What is the most critical metric in a funnel chart?
The drop-off rate (churn) between adjacent steps, which pinpoints the exact stage where the largest friction occurs.
