Why use this JSON to chart tool

Three chart types

Bars for comparison, lines for trends, pie for shares — switch with one click, no spreadsheet detour.

Free field mapping

Numeric fields are detected automatically; swap the X axis and series any time, plot multiple series together, nested fields are flattened to dot paths.

Theme-aware colors

Chart colors follow the site theme and stay readable in dark mode — screenshots are presentation-ready.

One-click PNG export

Export the finished chart with its background as a PNG that drops straight into docs, reports and slides.

Local & private

Business data is rendered entirely in your browser — never uploaded, never stored.
