Turn Raw Data Into Charts Instantly
Stop wrestling with spreadsheet software or expensive charting libraries. This free data visualizer lets you paste raw CSV or JSON data and immediately see it rendered as a professional chart. Choose from bar, line, pie, doughnut, and horizontal bar chart types.
Supported Data Formats
- CSV / TSV — Standard comma or tab-separated data with a header row. Automatically detects the label and value columns.
- JSON Array — An array of objects like
[{label: "A", value: 10}]. Supports common key names like name, category, count, amount.
Export Options
Export your chart as a high-resolution PNG for presentations and documents, or as SVG for scalable web graphics. Charts render at your device's native resolution for crisp output on Retina/HiDPI displays.
Smart Data Statistics
Below the chart, see instant statistics including data point count, minimum, maximum, average, and sum values — helping you understand your data at a glance.
Privacy-First Design
All chart rendering uses the HTML Canvas API in your browser. Your data never leaves your device. There are no uploads, no accounts, and no tracking.
