Visualise JSON as a chart

Have an API response or an export as a JSON array? Open or paste it, and every key becomes a column you can chart.

What JSON is supported

The data must be an array of objects, such as [{"month": "2026-01", "sales": 10}]. Keys are collected in the order they first appear, so objects with missing or extra keys still line up in one table.

Numbers, strings, booleans and nulls
Nested values are kept as JSON text
Open a .json file or paste the text

From keys to axes

Keys holding dates and numbers suggest a line over time; keys holding categories suggest bars or a pie. Choose any key for the X axis and any numeric key for the Y axis.
